VISHAY 159 PUL-SI Series Snap-in Aluminium Electrolytic Capacitor - 400

The VISHAY 159 PUL-SI Series represents a class of ultra-power, long-life, snap-in aluminium electrolytic capacitors designed for demanding electronic applications. Engineered for exceptional performance and reliability, these capacitors are built to endure high-stress environments, featuring a low Equivalent Series Resistance (ESR) and a high ripple current capability. This makes them an outstanding choice for circuits that require stable power delivery and efficient filtering, minimising heat generation and enhancing overall system longevity.

Housed in a compact, cylindrical aluminium case insulated with a distinctive blue sleeve, these polarised capacitors offer a remarkably long operational life. They are rated for 5000 hours at a maximum operating temperature of 105°C, ensuring dependable performance in thermally challenging conditions. The snap-in terminals facilitate secure and straightforward mounting on printed circuit boards (PCBs), providing a robust mechanical connection that is resistant to vibration.

Key Applications

These high-performance capacitors are ideally suited for a broad spectrum of industrial and commercial uses. They excel in solar photovoltaic (PV) inverters, where consistent energy conversion is critical, and in standard and switched-mode power supplies (SMPS) for effective smoothing and filtering. Additional applications include general-purpose industrial systems, audio and video equipment, and energy storage within pulse discharge systems, where their high reliability and robust construction are paramount.
