Vishay Intertechnology, Inc. 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 degrees C and high ripple current to 19.76 A at +85 degrees C in large 76 mm by 146 mm and 76 mm by 220 mm case sizes.

Recommended: 20A All-SiC 1.2kV Six-Pack for 5-15kW Three-Phase Designs

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 250V to 450V. 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 to +85 degrees 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 rail systems, 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.
