400 V and 450 V Devices Offer High Ripple Current to 6.77 A at 105 °C in 15 Large Case Sizes From 35 mm by 50 mm to 45 mm by 100 mm
Vishay Intertechnology introduces a new series of 400 V and 450 V snap-in, four-terminal aluminum electrolytic capacitors. The new series comes with 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 Intertechnology BCcomponents 299 PHL-4TSI series touts to reduce 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 released offer:
- High ripple current from 2.45 A to 6.77 A, allowing designers to utilize fewer components to meet the requirements of applications connected to a three-phase mains.
- 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 capacitors can replace banks of large screw terminal devices connected by a bus-bar with smaller parts connected by a PCB lowering 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 polarized 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.
