Vishay Intertechnology launches snap-in power aluminium capacitors

Vishay Intertechnology, Inc, one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors), has announced the launch of a new series of miniature snap-in power aluminium electrolytic capacitors. It comes with a higher power density designs.

The Vishay BCcomponents 193 PUR-SI series offers up to 30 % higher ripple current than standard solutions in similar case sizes. The aluminium capacitors provide a longer useful life.

It comes with ripple currents up to 3.27 A. The devices allow designers to utilize fewer components to save board space and lower costs. Their long useful life of 5,000 hours at +105 °C permits use in demanding applications requiring more than 25 years lifetime from capacitors in ambient temperatures up to +60 °C.

“Featuring a cylindrical aluminium case, insulated with a blue sleeve, 193 PUR-SI series devices feature rated voltages to 500 V in 25 compact case sizes ranging from 22 mm by 25 mm to 35 mm by 60 mm. The RoHS-compliant capacitors are available with 3-pin keyed polarity snap-in terminals.

“As polarized aluminium electrolytic capacitors with a non-solid electrolyte, the devices are ideally suited for smoothing, buffering, and DC-Link filtering in switch mode power supplies, motor drives, solar inverters, industrial air conditioners, and welding equipment, the company said.
