Power Aluminum Capacitors Feature Long Life of 10,000 Hours at +85 ̊ͦC

Vishay Intertechnology, Inc. introduced a  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 mW, 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 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.

Samples and production quantities of the 110 PHT-ST capacitors are available now, with lead times of 10 to 14 weeks. Pricing per piece depends on case size, voltage, and capacitance, and starts at $20.00 per piece.
