MKP 339 X2/MKP 338 2 X2/MKP 336 2 X2

From Vishay Intertechnology Inc. comes three X2 electromagnetic interference (EMI) suppression film capacitors with an increased maximum main voltage of 310Vac and a wide range of lead pitches and capacitance values.

While most standard EMI suppression film capacitors provide a voltage rating of 275Vac to 305Vac, the MKP 339 X2, MKP 338 2 X2, and MKP 336 2 X2 devices offer designers an increased voltage rating while continuing to meet safety approvals and maintaining the same compact dimensions, claims Vishay.

Utilizing the latest film technology to offer lead pitches from 7.5mm to 27.5mm, capacitance values from 1nF to 4.7?F, and a permissible DC voltage of 630V, the capacitors are optimized for standard across the line applications (50/60Hz) in power supplies, electronic ballasts, EMI filters, CRT and LCD TVs and monitors, and white goods.

Climatic tested according to EN 60068-1 (55/110/56/B), the encapsulation of the devices consists of a flame retardant UL-class 94 V-0 plastic case, which is epoxy resin sealed. Supplied loose in box or taped on ammopack or reel, the Pb-free capacitors are RoHS-compliant and feature tinned wire leads.

Samples and production quantities of the new X2 EMI suppression film capacitors are available now, with lead times of 8 to 10 weeks for larger orders. Pricing varies by capacitance value and lead pitch.
