Aluminium Electrolytic Capacitors –ALS81H125QS025 application field and working principle

Aluminium electrolytic capacitors are a type of capacitor commonly used in many electronics applications. They have a high capacitance value and a relatively small form factor, making them ideal for use in applications where space is at a premium. Aluminium electrolytic capacitors are especially popular in power supplies, where they help to store energy and regulate the voltage output.

The ALS81H125QS025 is a type of aluminium electrolytic capacitor. It has a capacitance of 1500 μF, rated voltage of 125V, and a rated ripple current of 800mA. This makes it suitable for use in power supplies and other DC voltage applications.

The working principle of an aluminium electrolytic capacitor is relatively simple. It consists of an anode, cathode and two aluminum plates which are separated by a layer of electrolyte. When a voltage is applied across the two metal plates, an electric field is created. This causes electrons to be pulled from the anode towards the cathode, thus creating an electric current which is stored in the form of electric charge. The stored electric charge is known as the capacitor’s capacitance.

Aluminium electrolytic capacitors are widely used in a variety of applications, such as in power supplies, high frequency circuits, and voltage regulators. In power supplies, they provide energy storage and regulate the output voltage level. In high frequency circuits, they are used as filters to reduce the presence of unwanted signals, while in voltage regulators they provide extra capacitance to help maintain the output voltage of the device. Overall, aluminium electrolytic capacitors are an important component in many modern electronic devices.

In summary, the ALS81H125QS025 is an aluminium electrolytic capacitor designed for use in power supplies and other DC voltage applications. It has a capacitance of 1500 μF, rated voltage of 125V, and a rated ripple current of 800mA.
