First automotive-grade ceramic capacitors with Y1 rating in SMD casing

Vishay Intertechnology, Inc. has introduced a new series of automotive-grade AC line-rated ceramic disc safety capacitors that are the industry's first with a Y1 rating to be supplied in a surface-mount casing. Combining their Y1 rating of 500VAC and 1500VDC with high capacitance to 4.7nF, the Vishay BCcomponents SMDY1 Automotive Series devices are designed to provide EMI/RFI suppression and filtering in harsh, high humidity environments.

AEC-Q200 qualified with PPAP available, the capacitors released today will be used in OBC, traction inverters, BMS, e-compressors, and AC/DC converters in EV, HEV, and PHEV vehicles. For these applications, the devices provide high humidity resistance with a Class IIB humidity grade (in accordance with IEC60384-14 annex I) and can withstand the 85/85/1000h test.

Allowing for surface-mount assembly with a reflow soldering process, SMDY1 Automotive Series capacitors decrease production costs. Unlike leaded components, the devices deliver a low, flat profile on the PCB to allow flat casings or backside PCB mounting without the clearance space needed by through-hole capacitors.

RoHS-compliant and halogen-free, the components consist of a copper-plated ceramic disc and feature encapsulation made of flame-resistant epoxy resin in accordance with UL 94 V-0. The devices are obtainable in two case sizes: the C case with a creepage distance of 10mm and the D case with a creepage distance of 14.5mm.
