Snap-in Power Aluminum Electrolytic Capacitors have 500 V rating.

Press Release Summary:




Supplied in blue sleeve-insulated, cylindrical aluminum case in 23 sizes from 22 x 25 mm to 35 x 60 mm, 157 PUM-SI series conserves board space in power supplies, industrial motor controls, and solar PV inverters by allowing designers to utilize one component instead of two 250 V capacitors. These polarized aluminum electrolytic capacitors with non-solid electrolyte are RoHS compliant and feature max operating temperature of +85°C at 500 V. Keyed polarity snap-in version is also available.



Original Press Release:



Vishay Intertechnology Extends Rated Voltage of 157 PUM-SI Snap-in Power Aluminum Electrolytic Capacitors to 500 V for Solar Inverters and Industrial Motor Control



Space- and Cost-Saving Devices Offer Long Useful Life of 5,000 Hours or More



MALVERN, Pa. – Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its 157 PUM-SI series of ultra-miniature snap-in power aluminum electrolytic capacitors with a higher rated voltage of 500 V. Designed for power supplies, industrial motor controls, and solar PV inverters, the enhanced devices save board space and lower costs by allowing designers to utilize one component instead of two 250 V capacitors.



Featuring a cylindrical aluminum case, insulated with a blue sleeve, the Vishay BCcomponents snap-in capacitors are available in 23 case sizes ranging from 22 x 25 mm to 35 x 60 mm. At 500 V, the devices feature a maximum operating temperature to +85 °C and a long useful life of ≥ 5,000 hours.



As polarized aluminum electrolytic capacitors with a non-solid electrolyte, 157 PUM-SI series devices are ideally 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.
