Vishay Intertechnology, Inc. introduced a new series of miniature snap-in power aluminum electrolytic capacitors that enables higher power density designs. According to the company, 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 allow developers to utilize fewer components. 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 x 25 mm to 35 mm x 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 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.
Samples and production quantities of the 257 PRM-SI series capacitors are available now, with lead times of 14 weeks.
