Vishay Intertechnology extends useful life of its power aluminium capacitors

Vishay Intertechnology, Inc., the American manufacturer of discrete semiconductors and passive electronic components, announced recently that the company has successfully extended the useful life of 500 V devices in its key offering 159 PUL-SI series of snap-in power aluminium capacitors. Vishay BCcomponents devices now offer a useful life of 5,000 hours at +105 °C for industrial motor control, solar PV inverters, and power supplies.

Vishay's 159 PUL-SI capacitors feature a cylindrical aluminium case fitted with a pressure relief valve and a blue sleeve insulation. The aluminium case size varies from 2 x 25 mm to 35 x 60 mm. As per the company's official specification the offering rated voltages from 200 V to 500 V. The devices feature high ripple current to 2.80 A, maximum ESR down to 150 mΩ at 100 Hz, and a maximum operating temperature to +105 °C.

The 59 PUL-SI series device with aluminium casing is ideally suited for smoothing, filtering, and energy storage in pulsed power applications and is surely the best in class polarized aluminium electrolytic capacitor with a non-solid electrolyte. The RoHS-compliant capacitors are also available in a keyed polarity snap-in version, Vishay's media release mentions
