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

MALVERN, Pa. — Vishay Intertechnology, Inc. 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.

Samples and production quantities of the 259 PHM-SI series capacitors are available now, with lead times of 15 weeks. Pricing depends on capacitance and voltage rating. For example, the price for 1500 µF / 250 V devices in the 35 mm by 45 mm case size is $4 per piece in 1000-piece quantities.
