Vishay 202 PML-ST series capacitors

Vishay Intertechnology, Inc. introduced a new series of screw-terminal aluminum electrolytic capacitors that allow designers to pack more energy storage into less space. Available in 11 case sizes ranging from 35mm by 60mm to 90mm by 220mm, the Vishay BCcomponents 202 PML-ST series offers high capacitance or voltage (CV) values in smaller case sizes than previous-generation solutions while providing increased ripple current to 49.6A, lower ESR down to 2mΩ, and a long useful life of 10000h 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 56000µF at 200V to 15000µF at 450V. For example, a CV rating of 2200µF/400V-previously available in the 65mm by 105mm case size-is now available in the smaller 50mm by 105mm 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 4700µF/400V 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 from 10 to 15years.
