Tantalum polymer capacitors are popular in many decoupling applications including high performance DC to DC converters. This created a perfect fit for polymer capacitors in telecom and industrial high performance applications. Now the automotive segment is showing an increased demand for these type of capacitors for use in infotainment and advanced driver assistance systems (ADAS). Most automotive applications require passive components to be qualified to the Automotive Electronics Council’s AEC-Q200 Stress Test Qualification for Passive Components. KEMET Electronics has addressed this need by developing new processes and materials to offer the market’s first polymer electrolytic capacitors qualified to AEC-Q200.
