The AEC-Q200 Ultra-Low ESR X8G range offers a very stable X8R High Q material system that provides excellent low loss performance.  The range is tested and approved to automotive specification AEC-Q200.


Optimized for lowest possible ESR, the electrode system provides low metal losses resulting in flatter performance curves and reduced losses at higher frequencies.


An extended operating temperature range of -55°C to 150°C accommodates modern high density micro electronics requirements. This range of high frequency capacitors is suitable for many applications where economical, high performance is required.
