Available now from TTI stock, Vishay’s new ceramic disk capacitors provide
high reliability for automotive applications. The AY2 Series
AEC-Q200-qualified, AC-line-rated ceramic disc safety capacitors are
designed to provide high reliability for Class X1 (440VAC) and Y2 (300VAC)
automotive applications in accordance with IEC 60384-14.3, 3rd edition.

Featuring U2J, Y5S, and Y5U ceramic dielectrics, the AY2 series is optimized
for on-board chargers and battery management in electric cars and plug-in
hybrid electric vehicles (PHEV), in addition to high-reliability industrial
applications. The capacitors offer a capacitance range from 10pF to 4700pF -
with tolerances down to ±10% - over a temperature range of -55C up to +125C.


AY2 series capacitors achieve an unmatched level of performance: they
withstand more than 2000 temperature cycles without a single failure, twice
the AEC standard. With their superior robustness, the capacitors provide the
highest levels of quality and reliability.

The devices consist of a silver-plated ceramic disc with tinned copper
connection leads offering 0.6mm diameters. AY2 capacitors are available with
straight leads with spacing of 5mm, 7.5mm, and 10mm. RoHS-compliant and
halogen-free, the devices' encapsulation is made of flame-resistant epoxy
resin in accordance with UL 94 V-0, says the company.
