Vishay introduces ceramic disc capacitors for Class X1 / Y1 applications

     Vishay introduces a new line of automotive grade AC line ceramic disk safety capacitors, the AY1 series. The new capacitor is the first of its kind in the industry to be AEC-Q200 certified for Class X1 (760 VAC)/Y1 (500 VAC) applications. Comply with IEC 60384-14.4 standard.

     Vishay BCcomponents AY1 series devices are suitable for electric (EV), hybrid (HEV) and plug-in hybrid electric vehicles (PHEV), especially for on-board chargers and DC/DC converters AC line filtering, as well as primary/secondary coupling. The device can withstand 85/85/1000 hours of temperature and humidity bias testing, 1000 -55 C to +125 C temperature cycles, and ten 10 kV unipolar pulses to meet the high reliability requirements of these applications.

     The AY1 series capacitors range in capacity from 470 pF to 4700 pF with a 20% tolerance. The device consists of a copper-coated ceramic disk with a diameter of 0.6 mm or 0.8 mm tinned copper-covered steel wire with a direct lead spacing of 10 mm or 12.5 mm. The device complies with RoHS and Vishay green standards, is halogen-free, and the housing is sealed with flame retardant epoxy resin, achieving UL 94 V-0 fire resistance rating.

     In addition to AY1, Vishay's existing AY2 series of automotive grade AC line ceramic disk safety capacitors have been expanded to two new devices with capacities of 6.8nF and 10nF respectively, which are the first such devices in the industry to pass AEC-Q200 certification. Suitable for Class X1 (440 VAC)/Y2 (300 VAC) applications according to IEC 60384-14.4.
