Electrolytic Caps handle Ripple up to 4.42A with Useful Life of 3,000 Hours at 105°C

Vishay Intertechnology, Inc. today introduced a new series of miniature snap-in power aluminum electrolytic capacitors. Designed 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 4.42A, 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 500V in 25 compact case sizes ranging from 22mm by 25mm to 35mm by 60mm. 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 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.
