Vishay Introduces AEC-Q200 Qualified, New Series of Ceramic Disc Safety Capacitors

Vishay Intertechnology

Vishay Intertechnology introduced a new series of Automotive Grade AC line rated ceramic disc safety capacitors that are the industry’s first such devices to offer AEC-Q200 qualification for Class X1 (760 VAC) / Y1 (500 VAC) applications in accordance with IEC 60384-14.4.

For electric vehicle (EV), hybrid electric (HEV), and plug-in electric vehicles (PHEV), Vishay BCcomponents AY1 series devices are optimized for AC line filtering and primary / secondary coupling in onboard chargers and DC/DC converters. With the ability to withstand 85 / 85 / 1000 h biased humidity testing, 1000 temperature cycles from -55 °C to +125 °C, and ten 10 kV pulses per polarity, the devices deliver high reliability for these applications.

AY1 series capacitors feature a capacitance range from 470 pF to 4700 pF, with tolerances of ± 20 %. The devices consist of a copper-plated ceramic disc with tinned copper-clad steel connection leads offering 0.6 mm or 0.8 mm diameters, and they are available with straight leads with a spacing of 10 mm or 12.5 mm. RoHS-compliant, halogen-free, and Vishay Green, the components feature encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0.

In parallel to the AY1, Vishay’s existing AY2 series of Automotive Grade AC line rated ceramic disc safety capacitors has been extended with two new components offering capacitance to 6.8 nF and 10 nF, respectively. The industry’s first such components to offer AEC-Q200 qualification for Class X1 (440 VAC) / Y2 (300 VAC) applications in accordance with IEC 60384-14.4.
