Vishay Intertechnology has introduced the BCcomponents SMDY1 Automotive Series, the industry’s first Automotive Grade AC line-rated ceramic disc safety capacitors with a Y1 rating in a surface-mount package. Rated at 500 VAC and 1500 VDC with capacitance values up to 4.7 nF, the series is designed for next-generation electric and hybrid vehicle applications. These capacitors target EMI and RFI suppression in demanding, high-humidity environments such as on-board chargers, traction inverters, battery management systems, e-compressors and AC/DC converters. Qualified to AEC-Q200 with PPAP support, the devices meet Class IIB humidity standards under IEC60384-14 and pass the rigorous 85/85/1000h test for reliability. 

By enabling surface-mount assembly via reflow soldering, the SMDY1 series reduces production costs, simplifies design and addresses clearance challenges associated with traditional through-hole capacitors. Two case sizes are available: C case (10 mm creepage distance) and D case (14.5 mm creepage distance). Encapsulated in flame-resistant epoxy resin (UL 94 V-0) with a copper-plated ceramic disc, the capacitors are RoHS-compliant and halogen-free, supporting safer and more sustainable designs.
