FAQ — Automotive Grade MLCC

What does AEC-Q200 qualification mean for MLCC?

AEC-Q200 is the Automotive Electronics Council stress test qualification for passive components. It ensures the MLCC can withstand temperature cycling, humidity, mechanical shock, and other reliability tests required for automotive use.

When should I specify soft termination MLCC?

Soft termination MLCC are recommended for applications with high thermal cycling, mechanical vibration, or board flex stress — such as EV powertrain, engine compartment electronics, and high-reliability industrial controls.

Can AIMLCC help with automotive MLCC PPAP documentation?

Yes. When you submit an RFQ for automotive MLCC, specify your PPAP requirements. AIMLCC will work with suppliers to provide available quality documentation including lot traceability and date code information.
