T599 +150°C Automotive Polymer Tantalum Capacitors

KEMET T599 Automotive Polymer Tantalum Capacitors feature fully qualified AEC-Q200 components with an operating temperature of up to +150°C in polymer technology. The solid-state polymer cathode system delivers low ESR, while the tantalum anode ensures reliability levels that exceed the lifetime use of a vehicle. This series delivers stable capacitance across voltage and temperature, no loss of capacitance due to aging or drying, and high humidity handling. KEMET T599 Automotive Polymer Tantalum Capacitors offer excellent shock and vibration performance, a low-profile design, and a benign failure mode in a small footprint.
