VISHAY PSM-SI Electrolytic Capacitor, 4700 µF, 25V, Snap-In, Long Life - 40

The VISHAY PSM-SI Series is a standard power miniature snap-in aluminium electrolytic capacitor, engineered for reliability and high performance in demanding electronic applications. Featuring a long operational life of 12000 hours at 85°C, this capacitor offers exceptional durability, making it a dependable choice for long-term installations where component failure is not an option.

Constructed with a non-solid electrolyte and a polarised aluminium design, the capacitor delivers a low equivalent series resistance (ESR) and a high ripple current capability of 2.8A. This makes it exceptionally effective for smoothing and filtering circuits, ensuring stable voltage output and minimising electrical noise in sensitive systems.

Encased in a robust, cylindrical aluminium housing insulated with a distinctive blue sleeve, the component is built to withstand rigorous use. It is engineered to be charge and discharge proof, enhancing its resilience in applications involving frequent power cycling or pulse operations. Its compact, space-saving design allows for efficient use of board real estate without compromising on capacitance or performance.

Ideal for a wide array of uses, this capacitor is a staple in general-purpose circuitry, industrial controls, and audio/video systems. It is particularly well-suited for standard and switched-mode power supplies, as well as for energy storage in pulse discharge systems. Its specified climatic category of IEC 60068 40/085/056 confirms its reliability across a broad operating temperature range from -40°C to 85°C.

With a substantial shelf life of 500 hours at 0V and 85°C, the capacitor maintains its performance characteristics even after extended storage. The VISHAY PSM-SI Series represents a fusion of longevity, robust construction, and electrical efficiency, providing a critical and reliable passive component for modern electronic design.
