Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often referred to as electrolytic capacitors, are passive electronic components mainly consisting of an aluminum oxide film coated anodized aluminum electrolytic plate, a separator, and electrolyte. The choice of such capacitors depends on a variety of factors such as the physical size of the capacitors, operating temperature, rated voltage, capacitance value, and so on. One such example is the 35YXG1000MEFC12.5X20.

The 35YXG1000MEFC12.5X20 is an aluminum electrolytic capacitor with an operating temperature range of -55C to + 105C, a rated voltage of 10V, a capacitance of 1000µF, a tolerance of 20%, and a 12.5mmx20mm size. It is used in a number applications like medical device, automobile, electronic equipment, communication, household appliances, and so on.

The working principle of an aluminum electrolytic capacitor is similar to that of other capacitors. When connected with a DC power supply, the side of capacitor with higher potential will attract and store electrons in the anode, while the side with lower potential will push away electrons from the cathode. In doing so, an electric field is created in the round wax container of the capacitor and force to interact with electrons, forming an capacitance. As a result, current will flow through the capacitor, allowing electricity to store for a certain amount of time.

In order to increase the capacitance and its subsequent storage in the aluminum electrolytic capacitor, some characteristics are required such as its physical size, rated voltage, temperature, and so on. The higher the physical size, the greater the capacitance, thus allowing more current to flow and higher capacity for storing electricity. Similarly, the rated voltage must be carefully selected as too high voltage can damage the capacitor. The operating temperature is also important as a too-high temperature can cause heat dissipation and corrode the components whereas too-low temperature can cause the electrolyte to freeze, thus damaging the board.

In conclusion, the 35YXG1000MEFC12.5X20 aluminum electrolytic capacitors are mainly used in applications such as medical device, automobile, electronic equipment, communication, and household appliances due to their high capacity for storing electricity, small physical size, and tolerance to external voltage. Furthermore, the capacitors can work based on the interaction between an electric field in the round wax container and electrons.
