Electrolytic capacitors enable reduced component count

A new series of 400 V and 450 V snap-in, four-terminal aluminum electrolytic capacitors has been announced by Vishay Intertechnology. They offer improved ripple current capability at an ambient temperature of 105°C in 15 large case sizes. Designed for power supplies and industrial and home appliance inverters, the Vishay BCcomponents 299 PHL-4TSI series reduces component counts and lowers costs while increasing mechanical stability and end-product lifetimes.

Featuring a cylindrical aluminum case with pressure relief, insulated with a blue sleeve, the devices offer high ripple current from 2.45 A to 6.77 A, allowing designers to utilise fewer components to meet the requirements of applications connected to a three-phase mains.

The capacitors have a high 105 °C temperature capability and long useful life of 5000 h 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 significantly lowers construction costs and enables soldering processing instead of manual mounting.

With larger case sizes than standard two-terminal snap-in capacitors — ranging from 35 mm by 50 mm to 45 mm by 100 mm — the devices limit the number of components required.

As polarised aluminum electrolytic capacitors with a non-solid electrolyte, 299 PHL-4TSI series devices are ideally suited for smoothing, filtering, and energy storage in pulsed power applications.

The devices are RoHS-compliant; their four-terminal configuration provides increased mechanical stability and keyed polarity.
