Vishay Intertechnology Extends Useful Life of 500 V 159 PUL-SI Series Snap-in Power Aluminum Capacitors to 5,000 h at +105 °C
Tuesday, April 18, 2017

vishay newVishay Intertechnology, Inc. (NYSE: VSH) today announced that the company has extended the useful life of 500 V 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 +105 °C. Featuring a cylindrical aluminum case with a pressure relief valve, insulated with a blue sleeve, 159 PUL-SI capacitors are available in a variety of case sizes ranging from 22 x 25 mm to 35 x 60 mm. 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.

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 RoHS-compliant capacitors are also available in a keyed polarity snap-in version.

Samples and production quantities of the 159 PUL-SI series capacitors are available now, with lead times of 12 to 14 weeks. Pricing varies by capacitance, voltage, and volume, and ranges from $1 to $10 per piece.
