Vishay 4700 µF Electrolytic Capacitor, 63 V DC, Snap-In, Long Life

The Vishay MAL205658472E3 is a miniature, long-life aluminium electrolytic capacitor from the 056 PSM series, engineered for demanding power management applications. This polarised, snap-in capacitor delivers high performance with its low equivalent series resistance (ESR), robust ripple current handling, and proven reliability of 5000 hours at 85°C.

Featuring a non-solid electrolyte, it is perfectly suited for applications requiring substantial energy storage and effective filtering across a wide frequency range. Its compact cylindrical design, encapsulated in a protective blue insulating sleeve, offers an excellent capacitance-to-cost ratio compared to other component technologies. A pressure relief vent on the aluminium case ensures operational safety.

Key Functions & Applications

This capacitor excels as both an input and output buffer in complex power circuits. As an input buffer, it provides critical backup energy during mains voltage dips, stores energy during power factor correction (PFC) adjustments, and prevents high-frequency switching noise from propagating back to the power source. As an output buffer, it acts as a current sink for inductors, smoothing and filtering output, while storing energy to help the DC/DC converter adapt to sudden changes in power demand.

Its combination of high capacitance (4700 µF), a 63 V DC rating, and robust construction makes it a core component in industrial power supplies, audio equipment, and various power management systems where stability and durability are non-negotiable.
