Vishay Aluminum Caps Rated 2,000 Hours at +85 °C

Vishay Intertechnology now offers a new series of aluminum electrolytic capacitors with a capacitance range from 68 µF to 820 µF for mains-side filter-buffer applications. The capacitors have ±20 % tolerance and a 2,000 hours useful lifetime rating at +85 °C.

The Vishay BCcomponents 093 PMG-SI family of capacitors is available in 400-V, 420-V, and 450-V voltage ratings, with an operating temperature range of -25 °C to +85 °C. The capacitors are targeted for use in many consumer, commercial, and industrial applications. A wide range of case sizes, from 22 mm to 35 mm in diameter and 25 mm to 50 mm in length, is available, allowing designers to minimize footprint and maximize longevity under a variety of space constraints.

Applications include use on the high-voltage side of switchmode power supplies for equipment such as set-top boxes for digital and satellite TV, motor controls for washing machines and refrigerator compressors, uninterruptible power supplies for banking, networking, and telecom, and a variety of other end products including consumer welding equipment.

The new capacitors are manufactured by Vishay in China. Support for the 093 PMG-SI series is also managed from Vishay offices in Europe, combining the benefits of offshore cost savings with local technical support for engineers in Europe.
