Space and Aero Solutions
Powering the Future of Space and Aero Performance using Critical Components and Materials
Next‑Generation Space, Aero, and MEA Systems Built on High‑Reliability Power, Sensing, and Switching
Space, Aero, and More Electric Aircraft platforms are converging around the same engineering reality: higher power density, tighter thermal margins, and mission profiles that demand unwavering reliability from launch to end‑of‑life. In LEO satellites, Ground Stations, and MEA architectures alike, designers increasingly rely on high‑performance commercial and automotive‑grade components to meet aggressive schedules, mass constraints, and harsh environmental conditions. Panasonic’s portfolio—spanning high‑precision resistors for stable sensing and control, Conductive Polymer Electrolytic Capacitors and Hybrid Capacitors for low‑impedance power integrity, rugged inductors for efficient conversion, and PhotoMOS® Semiconductor Relays for isolated, long‑life switching—provides the electrical stability, thermal robustness, and vibration tolerance these systems require. Together, these technologies strengthen spacecraft power buses, stabilize MEA actuation and avionics, enhance ground‑station availability, and ultimately help deliver the next generation of resilient, high‑performance Space and Aero systems.
LEO Satellites
LEO Satellites Redefine Space Hardware by Prioritizing Cost, Speed, and Smart Use of High‑Reliability Components
- Steady, Precise Operation Across Power and Core Subsystems: High‑Precision Thick‑Film Chip Resistors use proprietary materials and processes to achieve ±0.1% resistance tolerance and ±25 ppm/K temperature coefficients while maintaining the durability of thick‑film construction; sulfur‑resistant versions add precious‑metal inner electrodes for stability in corrosive environments, giving designers the combination of environmental resilience and long‑term electrical accuracy.
- Engineering Within Strict Mass and Volume Limits: Bulk capacitance is usually the first place mass and volume limits get tight, because dense power networks often rely on large banks of MLCCs that eat board area. SP‑CAP™ Polymer Aluminum Capacitors offer high capacitance, low ESR, and stable performance in a compact, low‑profile package, often replacing multiple ceramics and reducing part count and board space. They also avoid the piezoelectric vibration of ceramic dielectrics and feature a self‑recovery behavior that tends toward higher resistance rather than a hard short—two traits that matter significantly more in spacecraft than in terrestrial electronics.
- Managing Heat in a No‑Convection Environment: EYG-R Series (Compressible Type) Graphite TIM PGS plays a key role in helping LEO satellites shed heat in an environment where convection isn’t available, and every watt must be managed via conduction and radiation. Its highly anisotropic graphite structure moves heat laterally with exceptional efficiency, spreading thermal loads away from hot components and into radiators or structural elements that can dissipate it. Because Graphite TIM is thin, lightweight, and compliant, it fits the tight mass budgets and stacked‑electronics geometries common in LEO buses while maintaining consistent contact pressure across thermal interfaces. The material’s stability under vacuum, radiation, and extreme temperature swings makes it well‑suited for five‑year, no‑maintenance missions, giving designers a reliable way to control hotspots and protect sensitive electronics in orbit.
Steady Performance in Space Environments
Thick Film Chip Resistors
Panasonic’s Thick Film Chip Resistors come in a wide range of sizes and values, including the compact, lightweight ERJ‑1GJ Series in the 0201 package. Built with a metal‑glaze resistive element and a robust three‑electrode structure, these resistors support automated placement, work with both reflow and flow soldering, and meet key industry standards including IEC 60115‑8, JIS C 5201‑8, JEITA RC‑2134C, and AEC‑Q200 (with noted exceptions), while remaining fully RoHS compliant.
For Steady, Precise Operation
SP-CAP™ Polymer Aluminum Capacitors
SP-CAP™ Polymer Aluminum are compact SMT devices that use a conductive polymer electrolyte in a layered aluminum structure, offering ultra‑low ESR, stable capacitance across their full temperature and voltage range, and high reflow tolerance, with values up to 820 µF and ratings from 2 V to 6.3 V—making them well‑suited for dense DC/DC converter input and output filtering.
For Engineering with Strict Mass & Volume Limits
Graphite TIM
EYG‑R Series Graphite TIM introduces thicker, highly compressible graphite sheets—now available in 250 µm and 350 µm options—that lower thermal resistance by conforming to rough or uneven surfaces, making them an efficient TIM for applications where convection isn’t available. Designed for easy, low‑cost installation compared to thermal grease, Graphite TIM maintains excellent heat resistance and long‑term reliability while reducing process steps because it is a sheet‑based material rather than a printable compound.

Ground Stations
Power, Integrity, and Interconnects: The New Priorities in Ground‑Station Design
Today's ground stations face a convergence of challenges as proliferating LEO constellations and expanding aerospace connectivity networks drive higher data rates and stricter requirements for continuous availability. The ground segment is increasingly the constraint on what a mission can accomplish, with reliability hinging on power systems that must prove their backup paths will work, digital platforms that demand low‑impedance and low‑noise power delivery, and instrumentation networks that must survive vibration, temperature swings, and continuous operation. These pressures expose weak points such as battery‑bank unpredictability, mid‑frequency PDN impedance peaks, noise coupling into wideband receivers, and vibration‑induced harness failures—making component stability, environmental robustness, and long‑life performance essential to building ground stations that can be trusted to operate whenever orbital mechanics say they must.
- Monitoring Continuous Power: Ground‑station power systems follow a familiar structure—utility feed, UPS, battery bank, generator, and conditioned DC distribution—but the real challenge is continuously proving that the backup path will work when needed. Battery banks are the most unpredictable element, with capacity fade and rising internal resistance that remain invisible without cell‑level measurement across high common‑mode voltages. That measurement path requires switches with high isolation, stable and extremely low resistance, minimal leakage, and no switching noise, all while surviving years of continuous operation. Panasonic’s PhotoMOS® Semiconductor Relays meet those demands with optically coupled MOSFETs that eliminate mechanical wear, provide high isolation, maintain stable on‑resistance, and switch cleanly without bounce or RF interference.
- Power Integrity Beneath the Digital Signal Chain: Software‑defined radios and baseband processors give a ground station its core capability, converting incoming RF into data and generating clean, encoded uplink signals. That work is done by dense FPGAs, SoCs, wideband converters, and low‑noise clocks, all of which place heavy demands on the power network. They draw fast, high‑magnitude transient currents on sub‑volt rails, making low impedance across the mid‑frequency region essential, and they are highly sensitive to supply noise that can show up as phase noise or spurious content in the received spectrum. POSCAP™ Tantalum-Polymer capacitors address this mid‑band gap with low ESR, low inductance, and stable capacitance, while their solid polymer electrolyte avoids the dry‑out failures that limit the life of conventional electrolytics in continuously powered equipment.
- Instrumentation, Test, and the Interconnect That Supports Them: A ground station is only as reliable as its ability to continually prove it’s working, which requires constant RF performance checks, electrical integrity testing, and calibration—much of it running in equipment racks or antenna‑mounted enclosures exposed to motion, vibration, and harsh temperatures. Those conditions make interconnects a critical failure point, since traditional wire harnesses can loosen, add mass, and demand manual inspection. CF1 & CF2 board‑to‑FPC connectors avoid those issues by replacing harnesses with flexible circuits and clip‑style contacts that hold firmly under shock and vibration, maintain low contact resistance, and withstand high heat. Designed as permanent internal interconnects, they reduce mass, assembly time, and vibration‑induced failures in the parts of the station where reliability is hardest to maintain.
Reliable Power Management
PhotoMOS®
Panasonic PhotoMOS® Semiconductor Relays are MOSFET‑based solid‑state relays designed for exceptionally low off‑state leakage and stable on‑resistance throughout their operating life. They offer low C×R values, high optical isolation between input and output, and support both DC and AC/DC load types, with driver options available in SSOP, SOP 4‑pin, and DIP 6‑pin packages. These devices are commonly referred to as photo relays, photovoltaic relays, solid‑state relays, or MOSFET relays, reflecting their broad use across signal‑level switching applications.
For Monitoring Continuous Power
POSCAP™ Tantalum-Polymer Capacitors
Hybrid Panasonic’s POSCAP™ solid‑electrolyte chip capacitors provide stable capacitance at high frequencies and elevated temperatures due to their low‑ESR design. Using a sintered tantalum anode and proprietary high‑conductivity polymer cathode, they achieve some of the lowest ESR levels in tantalum‑polymer technology, ensuring strong performance in fast, noise‑sensitive power environments. Their compact package options maximize volumetric efficiency for dense PCB layouts, while their robust construction delivers high reliability and heat resistance—making POSCAP™ well suited for digital and high‑frequency applications requiring long‑term power stability.
For Power Integrity Beneath the Digital Signal Chain
Automotive Connectors
Space ground stations are increasingly adopting flexible printed‑circuit (FPC) cabling as systems become more compact, modular, and weight‑sensitive. FPC is now used across a wide range of station subsystems, including RF monitoring modules, control panels, antenna‑pedestal electronics, power‑distribution units, and environmental‑sensing assemblies. A newer and rapidly expanding application is battery‑management and backup‑power systems, where FPC helps reduce overall mass and eliminates wiring‑related failures that can occur with traditional harnesses and discrete electrical connections. To support these evolving architectures,

More Electric Aircraft (MEA)
Electrifying Aerospace: Panasonic Components for MEA Power, Control, and Reliability
MEA (More Electric Aircraft) systems rely on components and materials that deliver high power density, thermal stability, and aerospace‑grade reliability. They require advanced electrical power conversion hardware, high‑voltage distribution networks, lightweight composite materials, precision motor‑control electronics, and ruggedized sensors capable of operating under vibration, radiation, and extreme temperature swings. MEA architectures also depend on efficient thermal‑management materials, EMI/ESD‑resistant components, and long‑life capacitors, resistors, and connectors—areas where Panasonic’s high‑reliability component portfolio (polymer capacitors, power inductors, relays, sensors, and heat‑spreading materials) directly supports the shift from hydraulic and pneumatic systems to fully electric actuation, power, and avionics subsystems.
- Power Conversion AC/DC: Film Capacitors play a quiet but essential role in MEA power conversion because they handle high voltage, high ripple current, and fast switching conditions better than many other capacitor types. In both AC/DC and DC/DC conversion stages, they’re used for functions where stability, low loss, and long life are critical.
- Generator: Inductors are central to how More Electric Aircraft (MEA) generators produce, condition, and deliver electrical power. In MEA architectures—where mechanical engine output is converted into high‑quality electrical power for actuation, avionics, and distribution—inductors support every major stage of generator electronics.
- Power Distribution: Relays are a foundational part of power distribution in More Electric Aircraft (MEA) because they provide controlled, reliable switching of high‑voltage, high‑current electrical paths that replace many traditional hydraulic and pneumatic systems. In MEA architectures—where electrical power is the primary means of actuation, propulsion support, and system control—relays ensure that power is routed safely, intelligently, and with aerospace‑grade reliability.
- Electronic Actuators/Pumps: OS-CON™ Aluminum-Polymer Solid Capacitors fit electric actuators and pumps in More Electric Aircraft because they deliver stable, low‑impedance power under the high currents, fast switching, and harsh thermal conditions typical of MEA electromechanical systems. These loads—flight‑control actuators, braking actuators, fuel pumps, coolant pumps, and ECS compressors—depend on tightly regulated DC power, and OS‑CON™ parts support that with characteristics that outperform many electrolytic alternatives.
- BESS/BMS: Anti‑sulfurated, High‑power, Wide‑terminal Chip Resistors are used throughout Battery Management Systems (BMS) in More Electric Aircraft because they deliver stable, contamination‑resistant performance in a high‑vibration, high‑temperature, safety‑critical environment. In MEA platforms—where batteries support engine start, emergency power, and high‑voltage DC buses—these resistors help ensure accurate sensing, reliable protection, and long‑life operation.
