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
