Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most ubiquitous passive components used in a wide range of electronic circuitry. They are widely used in many applications such as power supplies, motor drives, amplifiers, instrumentation, and audio/video equipment. The ALS81H122KE500 is a high value, long life and high temperature aluminum electrolytic capacitor used in many applications.The ALS81H122KE500 capacitor is a polarized capacitor, which means that it has positive and negative terminals that must be connected in the correct direction during installation. The terminals are usually marked with a ‘+’ (positive) and ‘-’ (negative) sign.The capacitor is composed of an aluminum shell, an anode and a cathode. The anode is an aluminum foil on which an oxide layer is grown. The cathode consists of a metal foil with a wet, conductive gel-like polymer, which is a liquid electrolyte. An electrical current is applied via the anode and cathode to form a capacitor structure within the aluminum shell.The ALS81H122KE500 has a maximum operating temperature of 125C and a capacitance of 120000uF. It has an endurance of 2000 hours at 125C and a leak current of less than 0.05uA. The aluminum shell provides the capacitor with a ruggedized construction which allows it to be used in vibration-prone environments.This capacitor is primarily used in high voltage applications such as in photovoltaic, energy storage, DC/DC converters, telecom, power control systems and resonant circuits. It can be used for energy storage, power switching, filtering, and as a storage device for power electronics. For example, the capacitor can be used for power factor correction in a power system to reduce flicker, power loss, and reduce harmonic distortion.The capacitor acts as an energy storage device by storing and releasing energy when the voltage applied to it increases or decreases. It also acts as an electronic filter by allowing only certain frequencies to pass through it. Finally, it acts as a noise filter to reduce the amount of noise present in a circuit.In addition to the applications mentioned above, the ALS81H122KE500 capacitor can also be used in motor control, power conditioning, RF power amplifier circuits, and LED lighting circuits. Due to its long life, high temperature and high capacitance, it is an ideal choice for use in these applications.The capacitor is a vital component in modern electronics and its use will only continue to grow as technology advances. Its ability to store and release energy makes it indispensable in many different applications. The ALS81H122KE500 aluminum electrolytic capacitor is an effective and durable choice for high voltage and power related applications.
