Ceramic Capacitors FAQQWhat is the difference between Automotive Grade (GCM, GRT) and standard grade (GRM) capacitors?

A
Applications

The GCM Series, which has higher reliability than the standard GRM, is recommended for life-critical applications, such as automotive (driving, turning, stopping, safety equipment). For information system such as car navigation, entertainment (such as car audio or DVD players), and body control such as wipers and power windows, the AEC-Q200 compliant GRT Series commercialized.
