Aluminum Electrolytic Capacitors

100NA100MEFC12.5X25 belong to Aluminum Electrolytic Capacitors. Aluminum electrolytic capacitors are polarized electrolytic capacitors with a larger capacitance per unit volume than other types. They are most commonly used in power supplies where high energy storage is necessary.

Application Field

The greatest advantage of aluminum electrolytic capacitors is their high capacitance, which can achieve a ratio of over 200 times that of the same volume of ceramic capacitors. In general, aluminum electrolytic capacitors can be divided into two types: high voltage and low voltage.

The 100NA100MEFC12.5X25 application field includes personal computers, power supplies and industrial applications where medium voltage and energy storage are required. 100NA100MEFC12.5X25 have extremely low equivalent series resistance, enabling them to handle high current surges and work in extreme temperature environments.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the principle of electrolytic dissolution of aluminum foil. The aluminum foil is etched into a cobweb mesh structure with certain porosity. The etched aluminum foil is the anode, and the oxide film formed on its surface is the oxide film. The formed capacitor has two layers of dielectric, including the oxide film formed on the aluminum foil and the electrolyte.

The two electrodes of 100NA100MEFC12.5X25 are connected in series. The electrolyte is applied between the two electrodes to form two independent capacitors. The current flows through the anode electrode and forms two capacitance values, one of which is lower than the other.

Capacitance

The capacitance of 100NA100MEFC12.5X25 is very high, which can achieved more than 200 times the capacitance of the same volume ceramic capacitor. Increasing the hole density, increasing the mass of electrolyte in the hole, and increasing the number of windings in a given volume can also increase the capacitance. 100NA100MEFC12.5X25 are designed to have a working temperature up to 125◦C and an operating life of up to 10,000 hours.

Conclusion

100NA100MEFC12.5X25 belong to Aluminum Electrolytic Capacitors and have application fields in personal computers, power supplies and industrial applications where medium voltage and energy storage are required. The capacitance of 100NA100MEFC12.5X25 is very high, achieving more than 200 times the capacitance of the same volume ceramic capacitor. 100NA100MEFC12.5X25 have extremely low equivalent series resistance, enabling them to handle high current surges and work in extreme temperature environments.
