Vishay extends voltage options for snap-in capacitors

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 aluminium case with pressure relief, insulated with a blue sleeve, the 299 PHL-4TSI capacitors offer high ripple current ratings from 1.9 to 7.6A, allowing designers to utilise fewer components to meet the requirements of applications. The 299 PHL-4TSI capacitors have a high 105°C temperature capability and long useful life of >5,000h while still being able to withstand high ripple currents.

The four-terminal snap-in capacitors can replace banks of large screw terminal capacitors 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 can sizes than standard two-terminal snap-in capacitors – ranging from 35 x 50mm to 45 x 100mm – the 299 PHL-4TSI series limits the number of components required.

As polarised aluminium electrolytic capacitors with a non-solid electrolyte, 299 PHL-4TSI devices are ideally suited for smoothing, filtering, and energy storage. The capacitors are Reach- and RoHS-compliant; their four-terminal configuration provides increased mechanical stability and keyed polarity.

Samples are available from catalogue houses in small quantities. Production quantities of all 299 PHL-4TSI values are available now, with lead times of 18 weeks.
