Snap-in aluminium capacitor range extended to 500V

Vishay Intertechnology has extended its 157 PUM-SI series of ultra-miniature snap-in power aluminium electrolytic capacitors with a higher rated voltage of 500V. Designed for power supplies, industrial motor controls, and solar PV inverters, the enhanced devices save board space and lower costs by allowing designers to utilise one component instead of two 250 V capacitors.



Featuring a cylindrical aluminium case, insulated with a blue sleeve, the Vishay BCcomponents snap-in capacitors are available in 23 case sizes ranging from 22x25mm to 35x60mm. At 500V, the devices feature a maximum operating temperature of +85°C and a long useful life of over 5,000 hours.
As polarised aluminium electrolytic capacitors with a non-solid electrolyte, 157 PUM-SI series devices are suited for smoothing, filtering, and energy storage in pulsed power applications. The RoHS-compliant capacitors are also available in a keyed polarity snap-in version.
