New Vishay Intertechnology Screw-Terminal Power Aluminum Capacitors Feature Long Life of 10,000 Hours at +85 °C
For Traction and Heavy-Duty Applications, Devices Offer High Ripple Current to 19.76 A in Two Large Case Sizes
MALVERN, Pa. — Oct. 16, 2014 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of screw-terminal power aluminum capacitors designed for traction and heavy-duty applications. Devices in the Vishay BCcomponents 110 PHT-ST series offer a long useful life of 10,000 hours at +85 °C and high ripple current to 19.76 A at +85 °C in large 76 mm by 146 mm and 76 mm by 220 mm case sizes.
Featuring a cylindrical aluminum case insulated with a blue sleeve and pressure relief in their sealing disc, the capacitors released today combine their long useful life with high capacitance of 6000 µF over a voltage range of 250 V to 450 V. Additional capacitance and voltage values are available on request. The devices offer tight tolerance of -10 % / +30 %, low maximum ESR down to 17.6 mΩ, and a wide operating temperature range from -40 °C to +85 °C.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, 110 PHT-ST series devices are optimized for rail traction in trains, subways, and light rails, in addition to power supplies in heavy-duty industrial applications. The capacitors are available with 13 mm high-current M5 and M6 discs, 18 mm high-current M6 discs, and 1/4-28 UNF discs. The devices are RoHS-compliant and available in standard or bolt-nut versions.
