Developed to deliver higher stability under harsh conditions, KEMET’s T591 series utilizes enhanced materials and design to offer high reliability in automotive applications or where high humidity and temperature are a concern. The polymer cathode technology ensures low ESR and a benign failure mode while the use of a tantalum anode offers high reliability, long life, and stable capacitance for the life of the hardware. The T591 series is RoHS compliant and halogen-free.

Typical applications include decoupling and filtering in a variety of market segments, with special emphasis in automotive applications such as infotainment and output in DC/DC converters where harsh conditions such as high humidity and temperature are a concern.
