The inductor’s soft saturation provides a predictable inductance decrease with increasing current, with stable inductance across the operating temperature range. With an operating voltage up to 350 V, the device is ideal for high current, high temperature power applications, including DC/DC converters, inverters, and filters for motor and switching noise suppression in hybrid, full-electric, and hydrogen fuel cell vehicles.

KEMET KONNEKT™ package allows two to four ceramic capacitors to be stacked vertically or horizontally while retaining the integrity of the part. It uses transient liquid phase sintering (TLPS) technology to bond component terminations together. The KONNEKT™ U2J capacitors can be used in both orientations, thus minimizing the component footprint, while maximizing the bulk capacitance of a stacked MLCC with design flexibility in mind.
