Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a fixed, non-polar capacitance device. It is composed of an aluminum oxide film formed on the surface of an anode aluminum foil and wound with a cathode foil on an insulating film. In actual circuit applications, aluminum electrolytic capacitors are commonly used in filter circuits, power supply circuits, and the reverse of motor drives.

35YXA33M5X11 is a kind of aluminum electrolytic capacitor, and its application field and working principle are as follows:

Application Field:

35YXA33M5X11 aluminum electrolytic capacitors are widely used in the following scenarios:

• It is mainly used in the single-phase inverter, UPS, switching power supply, servo motor, frequency converter and other DC cooling circuit for power electronics.
• It is also suitable for wide temperature range application, such as data acquisition and process control system.
• Suitable for high frequency response, high pulse current power source filter circuit.
• Suitable for the main circuit or by-pass circuit for high-speed gear box and servo drive.
• Suitable for all kinds of power electronic circuit control circuit.

Working Principle:

The working principle of 35YXA33M5X11 aluminum electrolytic capacitors is based on the principle of electrochemical reactivity, which consists of the anode aluminum foil, the electrolytic medium, and the cathode aluminum foil. The production process of aluminum electrolytic capacitors is determined by the following characteristics of aluminum oxide film: porous structure, continuous and uniform distribution of particles, high conductivity, lead edge overflow. Through chemical reaction, the electrolyte penetrates into the porous structure of the oxide film on the surface of the anode aluminum foil, and the oxide film is formed by chemical deposition reaction of the anode aluminum, so that the capacitance is guaranteed and the insulation performance is enhanced. During the operation of aluminum electrolytic capacitor, the electrolyte ionizes and decomposes the reaction after positive potential is applied to the anode aluminum foil, then the oxide film is formed and the peripheral electrolyte is neutralized. When the reverse voltage is applied, the electrochemical reaction is reversed and the oxide film and the electrolyte are restored to their original states.

The working principle of aluminum electrolytic capacitors is simple, but their actual application needs to take into account the application environment, performance parameters and other factors, only the combination of the two can obtain more ideal application effects.
