First AEC-Q200 Qualified Ceramic Disc Capacitors for Class X1 / Y1 Applications
Vishay Intertechnology, Inc. today 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 (760Vac) / Y1 (500Vac) 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.
With the ability to withstand 85 / 85 / 1000 h biased humidity testing, 1000 temperature cycles from -55°C to +125°C, and ten 10kV pulses per polarity, the devices deliver high reliability for these applications.
AY1 series capacitors feature a capacitance range from 470pF to 4700pF, with tolerances of ±20%. The devices consist of a copper-plated ceramic disc with tinned copper-clad steel connection leads offering 0.6mm or 0.8mm diameters, and they are available with straight leads with spacing of 10mm or 12.5mm.
RoHS-compliant, halogen-free, and Vishay Green, the components feature encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0.
Device Specifications:
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 6.8nF and 10nF, respectively. The industry's first such components to offer AEC-Q200 qualification for Class X1 (440Vac) / Y2 (300Vac) applications in accordance with IEC 60384-14.4.
