VISHAY 157 PUM-SI Series Electrolytic Capacitor - 450
High-performance VISHAY 100µF snap-in capacitor for power supplies, filtering & industrial use. 5000h @ 85°C life, 400V DC.
The VISHAY 157 PUM-SI Series is a premium power ultra-miniature snap-in aluminium electrolytic capacitor, designed to deliver exceptional performance in compact spaces. Engineered for high reliability and long service life, this capacitor series is an excellent choice for demanding electronic circuits where consistent performance is critical.
These polarised capacitors feature a non-solid electrolyte housed within a robust cylindrical aluminium case, which is insulated with a distinctive blue sleeve. This construction achieves a remarkable balance of large capacitance values within very small physical dimensions, making them ideal for modern, space-constrained designs. They are rated for a useful life of 5000 hours at a maximum operating temperature of 85°C, providing long-term stability and reliability.
The snap-in terminal design ensures a secure and stable connection to printed circuit boards, facilitating reliable mounting and excellent electrical contact. This series is well-suited for a wide range of industrial and consumer applications, including general-purpose circuits, audio and video systems, and various power management functions. They perform superbly in smoothing and filtering applications, as well as in both standard and switched-mode power supplies (SMPS). Additionally, their characteristics make them effective for energy storage in pulse power systems.
With a broad operating temperature range from -25°C to +85°C, the capacitors are suitable for use in diverse environmental conditions. Key electrical specifications ensure they meet the needs of modern electronics, offering low equivalent series resistance (ESR) and a high ripple current rating for efficient operation.
