Aluminum electrolytic capacitors are one of the most commonly used electric components for power supply in many electronic circuits. WBR30-250A is an aluminum electrolytic capacitor with a rated voltage of 30V and a capacitance of 250 μF. It is mainly used in couplings, noise filters, and power supply circuit decouplings. This article will explain the application field and working principle of WBR30-250A.

First of all, the application field of WBR30-250A is relatively wide. This product is mainly used in stepper motor start-up control circuits, LCD displays, air conditioners, refrigerators, projectors, electronic organs, computers, household appliances, electric doors, surveillance cameras, and other electric circuits that require coupling and filtering. As it has a high ripple current capacity, it is widely used as an electric filter circuit to filter out interference signals. It is also often used to provide a stable power supply, which can better ensure the normal operation of electronic equipment.

The working principle of the WBR30-250A capacitor is mainly based on an electrolyte container formed by a container and a cover along with its anode and cathode. The anode is generally made of aluminum foil, and the electrode combines the active material with the electrolyte. In the container, the electrolyte is divided into two with the diaphragm and the cathode, forming a negative and positive component. The aluminum foil acts as the cathode, and when a voltage is received, a positive electrostatic force is generated that drives the electrolyte into the gap gap between the two foils; the inner surface of the aluminum foil, filled with a thin layer of oxide film. When the voltage is removed, the electric field disappears, and the electrolyte returns. During the process, electric charges are stored.

In summary, WBR30-250A aluminum electrolytic capacitor is a relatively common electric component with a voltage rating of 30V and a capacitance of 250 μF. Its application field is relatively wide, and it is often used to filter out interference signals and provide a stable power supply. At the same time, its working principle is mainly based on the principle of electric field storage, which allows electric charges to be stored in the diaphragm under the action of positive electrostatic force.
