Vishay Intertechnology Snap-in Power Aluminum Capacitors Save Space, Lower Costs for Power Supplies, Solar Inverters, and Motor Controls

Devices Offer Increased Ripple Current to 4.42 A and Useful Life of 3,000 Hours at 105 °C

MALVERN, Pa. — May 16, 2018 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of miniature snap-in power aluminum electrolytic capacitors. Ideal for power supplies, solar inverters, and industrial motor controls, the Vishay BCcomponents 259 PHM-SI series combines 30 % higher ripple current than previous-generation components with a long useful life.

With ripple currents up to 4.42 A, the devices released today allow designers to utilize fewer components to save board space and lower costs. Their long useful life of 3,000 hours at 105 °C permits use in demanding applications requiring more than 10 years of lifetime from capacitors in ambient temperatures to 60 °C.

Featuring a cylindrical aluminum case, insulated with a blue sleeve, 259 PHM-SI series devices feature rated voltages to 500 V in 25 compact case sizes ranging from 22 mm by 25 mm to 35 mm by 60 mm. The RoHS-compliant capacitors are also available with 3-pin keyed polarity snap-in terminals.

As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the devices are ideally suited for buffering, filtering, and energy storage in compact power applications, including power supplies for server farms or industrial tools such as plasma cutters; motor drives for compressors in industrial cooling systems; and industrial lamp drivers for UV water treatment systems.
