Vishay Intertechnology Extends 159-PUL-SI Snap-in Power Aluminum Capacitors With Rated Voltage to 500 V at +105 °C
Devices Offer High Ripple Current to 2.80 A Over Full Lifetime for Solar Inverter and Industrial Motor Control Applications
MALVERN, Pa. — Dec. 19, 2013 —Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended its 159 PUL-SI series of snap-in power aluminum capacitors to a high rated voltage of 500 V at +105 °C. Designed for solar PV inverters, industrial motor controls, and power supplies, the enhanced devices feature a long useful life, high ripple current to 2.80 A and +105 °C, and max. ESR down to 150 m Ω at 100 Hz.
Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, the new Vishay BCcomponents snap-in capacitors released today are available in a variety of case sizes ranging from 22 x 25 mm to 35 x 60 mm. At 500 V, the devices feature a maximum operating temperature to +105 °C and useful life of >3000 hours.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 159 PUL-SI series devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications. The capacitors are also available in a keyed polarity snap-in version.
