Vishay / BC Components AY1 Automotive Grade AC Capacitors are ceramic disc capacitors with Class X1 and Class Y1 versions. The Class X1 capacitors are designed for 760VAC rated voltage and Class Y1 capacitors are designed for 500VAC rated voltage. These capacitors withstand 85/85/1000h test and are able to pass 1000 temperature cycles. The AY1 safety capacitors are AEC-Q200 qualified and feature high reliability and single layer AC disk. Typical applications include capacitors for AC line filter and primary-secondary coupling on battery chargers and filter capacitors on DC/DC converters for PHEV/EV and HEV.
