    While Bluetooth Low Energy (BLE) may not be part of your electronic designs just yet, odds are that will soon change.

    Capacitors may seem simple enough, but specifying them has actually grown more complex in recent years. The reason why comes down to freedom of choice. The universe of capacitors has expanded greatly over the past few years, in large part because of capacitor designs that take advantage of advances in conductive polymers.

    Many of the automation systems that increasingly appear in our daily lives have a fundamental need to sense the presence and movement of human beings. Whether that system simply shuts off the lights to save energy at home or triggers an emergency response in a health care facility, accurate motion sensing is a crucial requirement. Passive infrared (IR) sensors are a well-known, cost-effective motion sensing technology for these applications. Getting the most out of these sensors, however, requires some engineering expertise.

    If you’ve spent any time looking for the right connector to use in a smart phone or other mobile device, you might believe that all fine-pitch, low-profile connectors are created equal. But they’re not. In spite of similarities in package size and pitch, at least on their datasheets, these connectors differ in subtle ways that can affect their reliability during the assembly process and in use. Here are the key technical factors to consider when looking for a reliable connector for use in mobile devices:

    Not so long ago, all relays performed their switching duties through electromechanical means. Today, however, engineers can also opt for solid-state relays that use semiconductors to switch their output circuits.

    Engineers who specify electrical products for industrial equipment tend to have a good working knowledge of UL ratings. However, one rating that gives many engineers trouble is UL 1604, which certifies electrical components for use in hazardous environments. We routinely field questions about UL 1604 and which products comply with it. Here are some answers.

    Optically-isolated relays inherently have a long lifespan, thanks to their lack of moving parts and the robustness of their solid state electronics. You can, however, make them last even longer by accounting for LED power losses. Keep in mind that LED power does not remain constant over time. Instead, all LEDs experience a power loss in proportion to the time that current is applied to them. With optically-isolated relays, including PhotoMOS, this loss of LED power affects the device’s operating characteristics and lifecycle.

    As solar farms and energy storage systems grow in scale, they increasingly require power relays that can safely cut off high DC voltages.  That’s where our new HE-V relay comes in. Designed specifically for alternative energy applications, this new 2 Form A power relay provides:
