These devices are ideal for use in computer and data communication networks, audio and video systems, instrumentation, information systems, automobiles, and military and aerospace applications.

The MALIEYN07DB522F42K is available in a variety of voltage ratings, ranging from 6.3V to 450V. Its capacitance is also customizable, ranging from 0.47μF up to 47μF. Other features include a working temperature range of -40 to 105 ℃, a long life of more than 5000 hours at 105℃, and a self-healing feature to enhance aging characteristics.

Working Principle of MALIEYN07DB522F42K

MALIEYN07DB522F42K utilizes a multi-layered structure composed of two electrodes, a dielectric layer, and a separator. One of the two electrodes is made of aluminum which acts as an anode, and the other one is made of a conducting material which acts as a cathode. When power is applied to the device, electrons move through the dielectric layer and onto the anode. This creates an electric field, which generates an electrochemical reaction that forms an oxide layer on the surface of the anode. The oxide layer functions as a dielectric layer, thus allowing the capacitor to store charge.

The MALIEYN07DB522F42K also has a self-healing mechanism. When the capacitor is in use and the dielectric oxide layer breaks down due to overvoltage, a current flows through the oxide layer. This current helps to recreate the oxide layer, thus restoring the capacitor’s original capacitance.

Conclusion

The MALIEYN07DB522F42K aluminum electrolytic capacitor is a reliable and versatile component for power circuit applications. It is available in a variety of voltage and capacitance ratings, has a long life span, and a self-healing feature. The device operates through the formation of an oxide layer that serves as a dielectric and stores charge. This article discussed its applications and working principles.
