Stable Capacitance at High Frequency and Temperature, with Low ESR/ESL Panasonic's Capacitor product line has been expanded with POSCAP Tantalum-Polymer Solid Capacitors. The POSCAP product line spans several Series of Solid Electrolyte Chip Capacitors which include the TPE, TQC, TPF, TPSF, TPB, TPC, TPG, and TPU Series. These solid capacitors utilize a sintered tantalum anode and a proprietary high conductivity polymer for a cathode. Panasonic's innovative construction and processing yields one of the lowest ESR level in Polymer Tantalum Capacitor technology, and exhibits excellent performance in high frequency applications. Offering a high volumetric efficiency for capacitance, POSCAP Capacitors are available in various, compact package sizes for a small PCB footprint. Additionally, POSCAP parts demonstrate a high reliability and high heat resistance, making them the ideal Chip Capacitor for digital, high-frequency devices and more.
