Vishay Intertechnology, Inc. (NYSE: VSH) today presented a brand-new series of mini snap-in power light weight aluminum electrolytic capacitors that make it possible for higher power thickness designs. The Vishay BCcomponents 193 PUR-SI collection offers up to 30 % higher ripple current than typical services in similar case dimensions, while offering a much longer useful life.

With surge currents approximately 3.27 A, the devices launched today permit developers to make use of less components to conserve board room and also lower costs. Their long beneficial life of 5,000 hrs at +105 ° C allows usage sought after applications needing greater than 25 years lifetime from capacitors in ambient temperatures approximately +60 ° C.

Featuring a cylindrical light weight aluminum instance, insulated with a blue sleeve, 193 PUR-SI series gadgets feature ranked voltages to 500 V in 25 portable situation sizes varying from 22 mm by 25 mm to 35 mm by 60 mm. The RoHS-compliant capacitors are also offered with 3-pin keyed polarity snap-in terminals.

As polarized light weight aluminum electrolytic capacitors with a non-solid electrolyte, the gadgets are ideally suited for smoothing, buffering, and also DC-Link filtering in switch setting power products, motor drives, solar inverters, industrial ac unit, and welding equipment.
