Useful life of snap-in power aluminum capacitors extended

MVishay Intertechnology has announced that they have extended the useful life of 500V devices in its 159 PUL-SI series of snap-in power aluminum capacitors. For solar PV inverters, industrial motor control, and power supplies, the Vishay BCcomponents devices now offer a useful life of 5,000 hours at +105C.   Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, the capacitors are available in a variety of case sizes ranging from 22mm x 25mm to 35mm x 60mm. Offering rated voltages from 200V to 500V, the devices feature high ripple current to 2.80A, maximum ESR down to 150mohm at 100Hz, and a maximum operating temperature to +105C.   As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the 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.
