25SEF82M

Aluminum-polymer capacitors are electronic components composed of an anode electrode, cathode electrode and electrolytic film. They are electrically similar to electrolytic capacitors and share many common characteristics, including polarity, voltage ratings, and capacitance range. However, compared to electrolytic capacitors, aluminum-polymer capacitors are extremely compact, lightweight, and have excellent high-frequency characteristics and improved stability over temperature and voltage. The 25SEF82M is an aluminum-polymer capacitor specifically designed for use in a variety of high-end automotive, industrial and consumer applications. This capacitor features an 8.2V rating, a 20000hrs lifetime and current capabilities of up to 2.8 A. This makes the 25SEF82M a highly reliable and efficient capacitor, ideal for a variety of applications.The 25SEF82M is typically used in battery-backup systems to provide reliable power supply, in power supplies to filter high frequency noise, as well as in motor controls and gate drivers in order to reduce EMI noise. In addition, it can be used in the output filter stage of switching power supplies to reduce AC ripple and improve efficiency.The working principle of the 25SEF82M is based on its ability to store electrical energy in its capacitor plates by means of an electrolytic film. This electrolytic film is a porous dielectric material which is inserted between the two plates and acts as a dielectric barrier has very high dielectric strength, high thermal stability and excellent charge/discharge characteristics. When voltage is applied across the capacitor plates, electrical energy is stored in the pores of the film, creating an electrical field. This field is maintained until the polarity is reversed or the voltage is removed from the capacitor plates.Since the electrolytic film is porous, the 25SEF82M features excellent self-healing properties and superior current ratings, over a wide temperature range. This makes it highly reliable and durable, with a long lifetime of up to 20000hrs. Moreover, aluminum-polymer capacitors also have low equivalent series resistance (ESR) and low-inductance values, making them desirable for applications with high-frequency transients and ripple.Overall, the 25SEF82M aluminum-polymer capacitor is an efficient, high-performance component well-suited for automotive electronics, industrial controls, battery chargers, switched-mode powersupplies, and many other applications requiring a reliable power source and EMI filtering.
