Snap-in Aluminum Capacitors Spec’d for 5,000 Hours at +105 C

Vishay Intertechnology, Inc. today announced that the company has 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 +105 degrees C. They are offered with capacitances from 56 µF to 1800 µF.

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 200V to 500V, the devices feature high ripple current to 2.80A, maximum ESR down to 150mΩ at 100Hz, and a maximum operating temperature to +105 degrees 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.
