What is AEC-Q200 ？

2022-10-18

The AEC-Q200 qualification is the global standard for stress resistance that all passive electronic components must meet, if they are intended for use within the automotive industry. Parts are deemed to be "AEC-Q200 qualified" if they have passed the stringent suite of stress tests contained within the standard.

The following table is taken from the standard as an example:

Grade	Temperature Range	Component Type	Typical Application
0	-50 to +150°C	Flat chip ceramic resistors, X8R ceramic capacitors	All automotive
1	-40 to +125°C	Capacitor networks, resistors, inductors, transformers, thermistors, resonators, crystals, and varistors, all other ceramic and tantalum capacitors	Most underhood
2	-40 to +105°C	Aluminium electrolytic capacitors	Passenger compartment hotspots
3	-40 to +85°C	Film capacitors, ferrites, R/R-C networks and trimmer capacitors	Most passenger compartment
4	0 to +70°C		Non-automotive

In order to meet a specific qualification grade the part has to undergo stress testing up to the highest temperature included within that grade.
