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

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.

Recommendation	GCM Series (AEC-Q200)	GRT Series (AEC-Q200)	GRM Series (AEC-Q200 non-compliant product)
Application (Typical examples of automotive equipment)	Engine control unit Cruise control unit Regulator Knocking control Airbag system Anti-locking break system Four-wheel steering system Automatic transmission Suspension control Power steering Igniter Critical control equipment ECU for autonomous driving Sensor for autonomous driving V2X system On Board Charger for EV BMS for EV Inverter for EV, etc.	Car Audio Car navigation Car air conditioner GPS Wiper Direction indicator Power window Electric door mirror Door lock, Keyless Entry Back sonar Car interior lighting Accessories related Infotainment Telematics module, etc.	Car Audio Car Navigation Car air-conditioning Global positioning system Wiper Direction indicator Power window Electric door mirror Door lock, keyless entry Backup sonar Car interior illumination Accessories Infotainment Telematics module, etc.

Specification (Test condition)

There are some differences between the GCM series, GRT series and GRM series, not only in their applications but also in terms of specification (test condition).

The following high reliability test conditions are applied to GCM series and GRT series as the high reliability is required for automotive application.

Other special specifications (test conditions) are available for certain products, so please contact us through the purchase route.
