A new series of Vishay BC Components miniature snap-in power aluminum electrolytic capacitors has been introduced by New Yorker Electronics.

The Vishay Snap-In Power Aluminum capacitors enable higher power density designs.

The Vishay 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 5.05A, the devices allow designers to utilize fewer components to save board space and lower costs.

Featuring a cylindrical aluminium case and insulated with a blue sleeve, 257 PRM-SI capacitors feature rated voltages to 500V in 25 compact case sizes ranging from 22mm x 25mm to 35mm x 60mm.

The RoHS-compliant devices are also available with 3-pin keyed polarity snap-in terminals.

Applications include: general purpose, industrial and audio / video systems; smoothing and filtering; and standard and switched mode power supplies.
