Snap-in Power Aluminum Capacitors Offers Compact Case Sizes Down to 20 mm by 25 mm

Vishay Intertechnology, Inc. 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.

Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue PET sleeve, the new Vishay BC components snap-in capacitors released today are available in 17 case sizes ranging from 20 mm by 25 mm to 35 mm by 45 mm, with voltages from 16 V to 100 V. The devices offer a wide temperature range from -40 °C to +105 °C, useful life of 2,000 hours at +105 °C, ripple current to 4.85 A, and ESR down to 14 mW.

As polarized aluminum electrolytic capacitors with a non-solid electrolyte, 256 PMG-SI series devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications for audio amplifiers, LED drivers, UPS systems, and solar power micro-inverters. The capacitors are lead (Pb)-free and RoHS-compliant.

Samples of the 256 PMG-SI series capacitors are available now. Production quantities are available with lead times of 10 to 14 weeks. Pricing for U.S. delivery varies by case size, capacitance, and voltage, and it ranges from $0.50 to $3.00 per piece.
