Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. The aluminum surface acts as the cathode, and is covered with an insulating oxide layer which acts as the dielectric of the capacitor. An electrolyte, which is also an insulating material, covers the oxide layer. Polarized capacitors are typically used in applications which require a wide range of voltages and high capacities.

35MH74R7M4X7 Application Field and Working Principle

The 35MH74R7M4X7 aluminum electrolytic capacitor is commonly used in applications that require high power outputs, such as in audio applications. It has a rated voltage of 350 VDC and capacitance of 7.4 uF. It is designed to provide a capacitance-to-voltage ratio of 1:20 at full rated voltage, ensuring a high level of stability over the life of the device.The aluminum electrolytic capacitor is a polarized capacitor. When voltage is applied to the capacitor, positive ions in the electrolyte solution migrate towards the cathode, which is the aluminum foil of the device. These positive ions build up on the aluminum surface, forming an insulating layer of oxide. This insulating layer serves as the dielectric between the anode and the cathode, and prevents current flow between the two electrodes. Charge is stored in the capacitor in the form of static electricity, and is released when the voltage is removed.

Aluminum electrolytic capacitors are a popular type of capacitor due to their low cost, high capacitance-to-voltage ratio and stability. They are used in a variety of applications, such as AC adapters, automotive electronics, consumer electronics, and industrial controls. They are also commonly used to reduce electrical noise in audio amplifiers.

The 35MH74R7M4X7 aluminum electrolytic capacitor is a reliable and cost-effective capacitor for high power applications. Its wide voltage range and high capacitance-to-voltage ratio make it a suitable solution for audio and other power-intensive applications.
