Snap-in capacitors offer ripple currents up to 5.05A
A new series of miniature snap-in power aluminium electrolytic capacitors that enables higher power density designs has been introduced by Vishay Intertechnology.
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 5.05A, the devices allow designers to utilise fewer components to save board space and lower costs.
Featuring a cylindrical aluminium case, insulated with a blue sleeve, 257 PRM-SI series capacitors feature rated voltages to 500V in 25 compact case sizes ranging from 22 mm by 25mm to 35mm by 60mm.
The RoHS-compliant devices are also available with 3-pin keyed polarity snap-in terminals.
As polarised aluminium 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.
