T591 Polymer Automotive Capacitors

KEMET T591 Polymer Automotive Capacitors are designed to deliver higher stability under harsh conditions of humidity and temperature. The series features polymer cathode technology for ultra-low ESR and improved capacitance retention at high frequency. The solid capacitor construction results in long and stable life time performance as required by automotive applications. These devices comply with nearly all of the requirements of the AEC-Q200 standard and are specially designed for DC/DC converters in automotive applications, where harsh conditions (high humidity and temperature) are a concern.
