Working Principle

The MAL203871101E3 aluminum electrolytic capacitor operates on the principle of electrolysis. In an electrolytic capacitor, the anode and the cathode are separated by an electrolyte, which will create a strong electric field in the space between them when a voltage is applied. This electric field creates electrical dipoles in the insulating electrolyte, and these dipoles are attracted towards the anode and the cathode. This creates a build-up of electric charge on the anode and the cathode. The capacitance of the device is determined by the area of the anode and the area of the cathode.

When a voltage is applied to the MAL203871101E3 aluminum electrolytic capacitor, a current will flow through the device, which will cause the charge on the anode and the cathode to increase. As the charge increases, the capacitance of the capacitor also increases. At a high enough voltage, the capacitance of the capacitor will reach its maximum value, which is known as the rated capacitance. The rated capacitance of the MAL203871101E3 aluminum electrolytic capacitor is 20µF.
