Vishay Intertechnology has introduced aluminium electrolytic capacitors with improved ripple current capability at an ambient temperature of 105°C. It is designed for power supplies for industrial and home appliance inverters. Vishay’s BC components 299 PHL-4TSI series reduces component counts and lowers costs, while increasing mechanical stability and end-product lifetimes.

Featuring a cylindrical aluminium case with pressure relief, insulated with a blue sleeve, the snap-in, four-terminal devices offer ripple current from 2.45A to 6.77A, allowing designers to utilise fewer components to meet the requirements of applications connected to a three-phase mains. The four-terminal configuration of the 299 PHL-4TSI increases mechanical stability and keyed polarity. The 400V and 450V devices are RoHS-compliant.

As polarised aluminium electrolytic capacitors with a non-solid electrolyte, 299 PHL-4TSI series devices are suited for smoothing, filtering and energy storage in pulsed power applications. The 299 PHL-4TSI capacitors have a 105°C temperature capability and delivery of 5,000 hours while still being able to withstand high ripple currents.

The capacitors can replace banks of large screw terminal devices connected by a bus-bar with smaller parts connected by a PCB. This lowers construction costs and enables soldering processing instead of manual mounting. With case sizes of 35mm x 50mm and 45mm x 100mm, the devices limit the number of components required.
