New 193 PUR-SI Series from Vishay

Vishay BCcomponents new 193 PUR-SI Series of miniature snap-in power aluminium capacitors enable higher power density with ripple current to 3.27 A and increased longevity with useful life of 5,000 hours at +105 °C. The 193 PUR-SI series offers up to 30 % higher ripple current than standard solutions in similar case sizes, while providing a longer useful life.

  • Available with 3-pin keyed polarity snap-in terminals

  • RoHS-compliant Market Applications:

  • Smoothing, buffering, and DC-Link filtering in switch mode power supplies, motor drives, solar inverters, industrial air conditioners, and welding equipment.

  • High ripple current allows designers to utilize fewer components to save board space and lower costs

  • Long useful life permits use in demanding applications requiring more than 25 years lifetime from capacitors in ambient temperatures up to +60 °C
