Vishay / BC Components SMDY1 AC Line Rated Ceramic Disc Capacitors

Vishay / BCcomponents SMDY1 AC Line Rated Ceramic Disc Safety Capacitors consist of a ceramic disc that is copper plated on both sides and encapsulated in a flame-retardant epoxy resin (UL94V-0). The Class X1 (760VAC), Class Y1 (500VAC) capacitors offer a capacitance range of 470pF to 4700pF while operating in a temperature range of -55°C to +125°C. Other features include a Y5U ceramic dielectric, a ±20% capacitance tolerance, and a high humidity class of IIB.
