What are AEC-Q200 Qualified Components?

June 14, 2016

The AEC, which is an abbreviation of the Automotive Electronics Council, is an industry organization promoting the standardization of reliability, or qualification standards, for automotive manufacturers originally, and automotive electronic component manufacturers subsequently. The AEC-Q series serves as the industry standard adopted for automotive electronic components, and the Q200 series focuses on passive components specifically.

AEC-Q200 standards are set to confirm the high reliability of products, including high-temperature/high-humidity resistance, thermal shock resistance, and durability for passives such as capacitors, resistors, inductors, etc., in an automotive environment. It is essential these components meet the high resistance to temperature and vibration necessary to protect against short circuiting.

The Automotive Electronics Council qualified passives to fit within grades, which are distinguished by operating temperature and listed as follows:

  Temperature Range Temperature Range Passive Component Type  
Grade Minimum Maximum (Unless otherwise specified and qualified) Typical / Example Application
0 -50ºC +150ºC Flat chip ceramic resistors, X8R ceramic capacitors All automotive
1 -40ºC +125ºC Capacitor Networks, Resistors, Inductors, Transformers, Thermistors, Resenators, Crystals and Varistors, all other ceramic and tantalum capacitors Most Underhood
2 -40ºC +105ºC Aluminum Electrolytic capacitors Passenger compartment hot spots
3 -40ºC +85ºC Film capacitors, Ferrites, R/R-C Networks and trimmer capacitors Most passenger compartment
4 0ºC +70ºC   Non-automotive

A number of passive manufacturers have responded with AEC-Q200 qualified components, having undergone the rigorous testing and met industry standards, ensuring these products are able to withstand the harshest automotive environment.

Diverse Electronics carries numerous series of AEC-Q200 qualified components from some of its key lines, including Yageo, Hitano, Chilisin, Coilmaster, Walsin, and ECS.
