Moving Capacitors From Your Hand to Your Dashboard
The need for automotive polymer electrolytic capacitors has grown as the automotive segment has shown an increased demand for high-performance capacitors for use in infotainment and advanced driver assistance systems (ADAS). In telecom and high-performance industrial applications, tantalum polymer capacitors have been used for many demanding decoupling applications, such as low voltage DC to DC converters.
Introducing Automotive Polymer Electrolytic Capacitors
Most automotive applications require passive components to be qualified to the Automotive Electronics Council’s AEC-Q200 Stress Test Qualification for Passive Components. Passing this qualification has been a challenge for polymer-based capacitors in the past. 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.
This application note introduces polymer electrolytic technology, the electrical performance of these parts, advantages about other capacitors, and how the commercial grade product was improved to pass the stringent AEC-Q200 guidelines.
