Vishay has introduced the industry’s first surface-mount ceramic disc safety capacitors with a Y1 rating (500 Vac / 1500 Vdc).
The SMDY1 Automotive Series is designed for EMI/RFI suppression and filtering in safety-critical, high-voltage circuits used in electric, hybrid, and plug-in hybrid vehicles (see data sheet here).
Target applications include:
- Onboard chargers (OBCs)
- Traction inverters
- Battery management systems (BMS)
- E-compressors
- Ac/dc converters
By offering a surface-mount format, these capacitors enable reflow soldering, reduce production costs, and provide a low-profile alternative to through-hole parts, an advantage for compact EV power electronics and flat casings.
The series is AEC-Q200 qualified with PPAP available, features a Class IIB humidity grade, and passes the 85/85/1000h test for durability in harsh environments. Two case sizes are available, with creepage distances of 10 and 14.5 mm.
