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.
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 components offering capacitance to 6.8 nF and 10 nF, respectively.
Samples and production quantities are available now, with lead times of eight weeks. For more details, checkout the AY1 Series datasheet.
