AY1 Automotive-Grade AC Safety Capacitors

Vishay / BC Components AY1 Automotive-Grade AC Capacitors are ceramic disc modules with Class X1 and Class Y1 versions. The Class X1 capacitors are designed for 760V_AC rated voltage, while the Class Y1 devices are designed for 500V_AC rated voltage. Vishay / BC Components AY1 Automotive Grade AC Capacitors withstand the 85/85/1000h test and feature 1000 temperature cycles. These single-layer AC disc safety capacitors comply with the IEC 60384-14 international safety standard. Typical applications include AC line filters and primary-secondary coupling on battery chargers as well as filter capacitors on DC/DC converters for electric vehicles (EVs), hybrid EVs (HEVs), and plug-in hybrid EVs (PHEVs).
