Working Principle

The UMF1A220MDD1TE is an electrolytic capacitor. This means that it consists of two layers of metal electrodes immersed in a liquid electrolyte in a cylindrical aluminium case. When a voltage is applied, it acts like a small battery, converting chemical energy into electrical energy. The electrodes in the capacitor are alternately connected to the positive and negative terminals of the power supply. When these electrical charges combine, an electric field is formed between the two electrodes, causing the electrons to move to one of the electrodes and reducing its potential. The opposite electrode then accumulates electrons, causing the potential on that side to exceed the applied voltage. This creates an electric field that stores energy in the form of an electric charge.

The basic working principle of the UMF1A220MDD1TE is that a voltage (V) is applied across the two electrodes. This causes a current to flow through the electrolyte between the two electrodes, resulting in ions and electrons being generated. The ions are attracted to one of the electrodes, where they are electrically neutralized, while the electrons are attracted to the other. As a result, the positive electrode accumulates a negative charge, and the negative electrode accumulates a positive charge, creating a voltage between the two electrodes.

In short, the UMF1A220MDD1TE is an electrolytic capacitor used to filter, block and buffer in various electronic circuits. It has a wide range of applications in power electronics, automotive electronics, industrial automation and communication equipment. Its working principle is based on the formation of an electric field between two electrodes which stores energy in the form of an electric charge.
