VISHAY Safety Capacitor Metallized PP 0.033µF X1 440VAC 15mm
VISHAY MKP3381 X1 safety capacitor, 0.033µF, 440VAC. Metallized PP, through-hole, 15mm lead pitch for interference suppression.
The VISHAY MKP3381 X1 Series is a high-reliability interference suppression film capacitor designed for critical safety applications. This radial, through-hole component utilises a polypropylene film dielectric with metallised film electrodes, delivering stable performance and excellent self-healing properties.
Encased in a flame-retardant plastic housing and sealed with epoxy resin, it offers robust protection against environmental factors and enhances operational safety. The capacitor features tinned wire leads for superior solderability and reliable electrical connections.
It is specifically engineered for standard across-the-line applications where X1 class safety certification is required. With a wide operational temperature range from -55°C to +105°C, it is suitable for demanding electronic environments.
