T591 +125°C 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 lifetime performance as required by automotive applications. KEMET T591 Polymer Automotive Capacitors 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, such as high humidity and temperature, are a concern.
