The 100ZLH820MEFC18X40 aluminum electrolytic capacitor systematically applies in various commercial, industrial, and consumer electronics applications. Such as the power supply of electronic instrumentation equipment, amplifier, industrial automation, and electronic products. Capacitors with this type of construction are commonly seen in a wide range of applications, including signal processing circuits and power supplies.

Working Principle of 100ZLH820MEFC18X40 Aluminum Electrolytic Capacitors

The 100ZLH820MEFC18X40 aluminum electrolytic capacitor internal structure is composed of a shell, a screw, a terminal, an outer sleeve and roll paper insulation. Commonly, an aluminum electrolytic capacitor usually uses a single-layer non-polarized electrolyte with an anode aluminum and cathode aluminum foil. The aluminum foil that is the anode of the capacitor is anetalized, thus forming a porous oxide film with high dielectric constant and greater capacitance on the surface of the aluminum foil.

Meanwhile, the electrolyte is contained within the capacitor and is positioned between the anode aluminum foil and the cathode. When a voltage is applied to the capacitor, the amount of current passing through the anode of the aluminum foil electrolytic capacitor increases, forming an electrolyte film electrolysis. The anode aluminum will become thinner and thinner due to electrolysis, and the gap between the aluminum foil and the electrolyte will become larger and larger, so that when the rated voltage is reached, the capacitor can still work normally.

The 100ZLH820MEFC18X40 aluminum electrolytic capacitor has an epoxy resin package that helps to prevent leakage of the electrolytic fluid and loss of capacitance. Also, the lead terminal adds a safe breaking point so that the current is safely discharged when the voltage is high enough.

Conclusion

The 100ZLH820MEFC18X40 aluminum electrolytic capacitor functions mainly as a power supply filter, voltage stabilizer, power amplifier and anti-interference. As a popular choice for a range of electronics applications, this type of capacitor provides high performance, long life and reliability.
