193 PUR-SI Miniature Snap-in Power Aluminum Electrolytic Capacitors

Vishay Intertechnology, Inc. has introduced the BC components 193 PUR-SI, a series of miniature snap-in power aluminum electrolytic capacitors with a capacitance range of 47 µF to 820 µF, it offers higher power density and 30% higher ripple current than other standard solution.

The new device provides a ripple current of up to 3.27A and a long useful life of 5000 hours at +105 °C, hence the device can be used in the application that requires a lifetime of 25 years from capacitors in ambient temperatures up to +60 °C.

The 193 PUR-SI series is available in a cylindrical aluminum case, insulated with a blue sleeve. The new device operates at a rated voltage of 500 V in 25 compact case sizes ranging from 22 mm by 25 mm to 35 mm by 60 mm and they are available with 3-pin keyed polarity snap-in terminals.

The polarized aluminum electrolytic capacitor with a non-solid electrolyte makes it ideal for smoothing, buffering, and DC-Link filtering in switch-mode power supplies, motor drives, solar inverters, industrial air conditioners, and welding equipment.
