New Vishay Intertechnology Series of Snap-in Power Aluminum Capacitors Offers Compact Case Sizes Down to 20 mm by 25 mm

Vishay 256 PMG-SI

Vishay Intertechnology introduced a new series of miniaturized snap-in power aluminum capacitors with high capacitance from 820 µF to 47,000 µF in compact cases down to 20 mm by 25 mm. Designed for audio, industrial, and general power supply applications, 256 PMG-SI capacitors offer a long useful life, high ripple current, and low ESR.
