Aluminum Electrolytic Capacitors are an important type of capacitors that are found in a variety of electronic devices, from consumer electronics to industrial applications. The ALS81H202KF450 is a specific type of aluminum electrolytic capacitor, and it is designed for a variety of uses. This article will discuss the application field and working principle of the ALS81H202KF450.

Application Field

The ALS81H202KF450 is most commonly used in power supply designs due to its high capacitance and low leakage current. It is also ideal for applications with high ripple currents or where stability and high reliability are important. These applications include automotive electronics, power supplies, converters, inverters, UPS systems, motor drives, and other heavy industrial equipment.

The ALS81H202KF450 is also widely used in professional audio equipment, instrumentation, security systems, and telecommunications equipment. It is also an essential component in touchsceen devices and computer keyboards, where it helps reduce noise and ensure a longer life of the device.

Working Principle

The ALS81H202KF450 is an aluminum electrolytic capacitor, so it relies on the principles of electrochemistry to function. It is made up of two electrodes called the anode and the cathode, separated by an electrolyte. When voltage is applied to the capacitor, the anode attracts the positive ions from the electrolyte while the cathode attracts the negative ions and forms a layer of oxide. This layer of oxide acts as a dielectric allowing a charge to be stored and released as needed.

The ALS81H202KF450 also features a coated aluminum anode to help ensure a long life and a low leakage current. This is achieved by controlling the thickness of the oxide layer, which is formed when the anode and cathode are charged. This oxide layer is also important for achieving a high capacitance, as it serves to increase the capacitance of the capacitor. The ALS81H202KF450 also features a high temperature-resistant coating, allowing it to perform well in more extreme operating environments.

The ALS81H202KF450 is a great choice for a number of applications, due to its high capacitance, low leakage current, high temperature resistance, and long life. Its ability to store a charge and release it as needed makes it an essential component in power supplies, professional audio equipment, security systems, and other industrial applications.
