Ceramic Disc Capacitors Are AEC-Q200 Qualified

Vishay Intertechnology’s latest series Automotive Grade AC line rated ceramic disc safety capacitors are said to be 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 (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 on-board chargers and DC/DC converters. The components can withstand 85h/85h/1,000h biased humidity testing, 1,000 temperature cycles from -55°C to +125°C, and ten 10-kV pulses per polarity.


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 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.
