Now Pack More Energy Storage with a New Capacitor

Vishay Intertechnology has unveiled a new series of screw-terminal aluminum electrolytic capacitors that allow designers to pack more energy storage into less space.

vishay-capacitor Available in 11 case sizes ranging from 35 mm by 60 mm to 90 mm by 220 mm, the Vishay BCcomponents 202 PML-ST series offers high capacitance/voltage (CV) values in smaller case sizes than previous-generation solutions while providing increased ripple current to 49.6 A, lower ESR down to 2 mΩ, and a long useful life of 10 000 h at +85 °C.

Featuring a cylindrical aluminum case insulated with a blue sleeve and pressure relief in their sealing disc, the electrolytic capacitors released today provide high CV combinations from 56 000 µF at 200 V to 15 000 µF at 450 V. For example, a CV rating of 2200 µF / 400 V — previously available in the 65 mm by 105 mm case size — is now available in the smaller 50 mm by 105 mm case size.

For CV ratings with a similar case size to previous-generation solutions, the capacitors offer improved ripple current and ESR. For example, a CV rating of 4700 µF / 400 V offers 12 % higher ripple current and 16 % lower ESR.

As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the RoHS-compliant devices are ideally suited for filtering, buffering, and energy storage in pulsed power applications with a required lifetime of 10 to 15 years. Typical end products include industrial motor drives; rail traction for trains and subways; welding equipment, HVAC, and UPS; wind turbines and solar power inverters; and medical X-ray equipment.
