Vishay Intertechnology Snap-in Power Aluminum Capacitors Enable Higher Power Density to Save PCB Space, Lower Costs

April 15, 2020 | About:

Miniature Devices Offer Increased Ripple Current to 5.05 A and Useful Life of 5,000 Hours at 85 °C

MALVERN, Pa., April 15, 2020 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (: VSH) today introduced a new series of miniature snap-in power aluminum electrolytic capacitors that enables higher power density designs. The Vishay BCcomponents 257 PRM-SI series offers up to 20 % higher ripple current than previous-generation solutions in case sizes that are up to 20 % smaller while providing longer useful life to 5,000 hours at 85 °C.

With ripple currents up to 5.05 A, the devices released today allow designers to utilize fewer components to save board space and lower costs. Featuring a cylindrical aluminum case, insulated with a blue sleeve, 257 PRM-SI series capacitors 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 devices 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 smoothing, buffering, and DC-Link filtering in switch mode power supplies used in medical, consumer welding, and test and measurement equipment, in addition to general industrial control and audio / video system applications.
