Vishay Intertechnology Inc. unveils the 193 PUR-SI Solar capacitors. The snap-in power aluminium capacitors claim a rated voltage of 500V at 50°C and a category voltage of 450V at 105°C, and ripple current up to 2.52A at +105°C and 100Hz.

The capacitors are packaged in cylindrical aluminium cases with a pressure relief valve. Case sizes range from 35mm x 30mm to 35mm x 60mm, with an insulated blue sleeve. The devices feature a maximum operating temperature to +50°C and useful life of 5,000 hours (no ripple current applied). At 450V the maximum temperature can be extended to +105°C, and the useful life is 6,000 hours.

As polarized aluminium electrolytic capacitors with a non-solid electrolyte, the 193 PUR-SI Solar devices are suited for smoothing, filtering, and energy storage in pulsed power applications. End products include solar PV inverters, industrial motor controls, and power supplies.

The 193 PUR-SI Solar series capacitors are available now, with lead times of eight to 14 weeks.
