Snap-in power aluminium capacitors save space in solar inverters

Miniature snap-in power aluminium electrolytic capacitors from Vishay BCcomponents are designed for power supplies, solar inverters, and industrial motor controls.

The Vishay BCcomponents 259 PHM-SI series combines 30 per cent higher ripple current than previous-generation components with a long useful life, claims Vishay.

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

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

The polarised aluminium electrolytic capacitors with a non-solid electrolyte, are particularly suitable 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, adds Vishay.

Samples and production quantities of the 259 PHM-SI series capacitors are available now, with lead times of 15 weeks.
