Vishay Intertechnology Introduces Snap-in Power Aluminum Capacitors for Solar Applications With 500 V Rated Voltage and Ripple Current to 2.52 A
MALVERN, Pa. — Nov. 5, 2012 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new series of snap-in power aluminum capacitors with a rated voltage of 500 V at 50 °C and a category voltage of 450 V at 105 °C. Targeted at solar applications, where the highest voltage is present under no load conditions, the 193 PUR-SI Solar devices also feature a long useful life and rated ripple current up to 2.52 A at + 105 °C and 100 Hz.
Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, the new 193 PUR-SI Solar capacitors are available in five case sizes ranging from 35 mm by 30 mm to 35 mm by 60 mm. At 500 V, the devices feature a maximum operating temperature to + 50 °C and useful life of 5,000 hours (no ripple current applied). At 450 V, the maximum temperature can be extended to + 105 °C and the useful life is 6,000 hours.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 193 PUR-SI Solar devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications. End products include solar PV inverters, industrial motor controls, and power supplies.
