DC/DC conversion can be an extremely tough application for electronic components. They must be able to handle high voltages and high reflow temperatures, yet still provide extremely low ESR values. Fortunately, Panasonic’s new SP-Cap™ lineup of polymer aluminum capacitors is purpose-built to thrive in DC/DC conversion circuits. In this article, get a general overview of features and performance, plus get more in-depth information about the high-humidity JX series and high-endurance KX series.
SP-Cap™ polymer aluminum capacitors are built to perform as critical input/output capacitors in DC/DC conversion applications. They provide ultra-low ESR values, high voltage options and the ability to withstand high reflow temps during the assembly process. An innovative design utilizing conductive polymer in layered aluminum gives them the resilience to perform consistently over time. Find options in the lineup delivering capacitance values up to 560µF and voltage values ranging from 2V to 25V.
