VISHAY - Electrolytic Capacitor, Screw, 10000 µF, ± 20%, 10000 hours @ 85°C - 63

The VISHAY 101 PHR-ST series electrolytic capacitor is a high-performance, screw-terminal aluminium capacitor engineered for demanding industrial and commercial applications. It features a polarised, non-solid electrolyte construction within a robust cylindrical case, insulated with a distinctive blue sleeve for easy identification and safety.

Designed to provide a high capacitance value in a compact form factor, this capacitor excels in applications requiring efficient energy storage and filtering. Its advanced design offers a superior capacitance-to-cost ratio, making it an economical choice for high-power circuits. The component is relatively insensitive to voltage spikes, enhancing system reliability and longevity.

A key performance feature is its high ripple current rating, which allows it to handle significant AC current on top of the DC bias without excessive heating or degradation. This is complemented by a low Equivalent Series Resistance (ESR), minimising power losses and improving efficiency in switching power supplies and other high-frequency circuits. The integrated pressure relief mechanism in the sealing enhances safety by preventing case rupture under fault conditions.

Primary Functions and Applications

In power management systems, it serves as a critical input buffer, storing energy when mains voltage dips and preventing high-frequency switching noise from propagating back to the power source. As an output buffer, it acts as a current sink for inductors, smoothing voltage output and providing energy while DC/DC converters adjust to changing load demands.

Its robust construction and specified operational lifetime make it ideal for continuous use in challenging environments. Common applications include power supplies for computers and peripherals, industrial automation equipment, telecommunications infrastructure, and networking hardware, where stable and reliable power delivery is
