Vishay Intertechnology Extends Voltage Rating Options for Four-Terminal Snap-in Aluminum Electrolytic Capacitors

New 350 V and 500 V to 600 V Capacitors Expand Available Capacitance-Voltage Combinations

MALVERN, Pa. — Oct. 16, 2024 — Vishay Intertechnology, Inc. (NYSE: VSH) is extending its 299 PHL-4TSI snap-in, four-terminal aluminum electrolytic capacitor family with new 350 V, 500 V, 550 V, and 600 V rated capacitors that greatly expand the range of capacitance-voltage combinations available to designers. 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 299 PHL-4TSI capacitors offer high ripple current ratings from 1.9 A to 7.6 A, allowing designers to utilize 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 > 5000 h 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 mm by 50 mm to 45 mm by 100 mm — the 299 PHL-4TSI series limits the number of components required.

As polarized aluminum 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 catalog houses in small quantities. Production quantities of all 299 PHL-4TSI values are available now, with lead times of 18 weeks.
