Aluminum Electrolytic Capacitors

477RZM016M1013

Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in the electrical and electronics industry. The 477RZM016M1013 is an aluminum electrolytic capacitor with a maximum capacitance of 13µF and a maximum operating voltage of 16V. It is manufactured by Nippon Chemi-Con and is the world’s third-largest manufacturer of aluminum electrolytic capacitors.

Aluminum electrolytic capacitors are unique in that they consist of a thin sheet of aluminum foil rolled up and placed in an electrolyte solution. The plate of aluminum acts as the cathodic electrode, while the electrolyte solution acts as the anode. The two electrodes are separated by an insulating plastic film, allowing for a very small distance between them.

The aluminum electrolytic capacitor’s application field include: power supply energy storage, buffering, signal coupling, storing pulsating signals, timing and regulation circuit, decoupling, high-frequency bypass, etc. When placed in an electrical circuit, the capacitor blocks direct current from passing through the circuit while allowing alternating current to pass through. This is known as capacitive reactance.

To measure the capacitance of a capacitor, an AC voltage is applied to the component. The current that is passed through the capacitor depends on the capacitance of the component. If the capacitance of the component is known, the current that passes through the component can be used to calculate the capacitance. The capacitance of a 477RZM016M1013 aluminum electrolytic capacitor is 13µF.

The working principle of the 477RZM016M1013 aluminum electrolytic capacitor is based on the electric double layer formed in the electrolyte between the aluminum foil electrodes. When a voltage is applied between the electrodes, an electric field is created which attracts ions from the electrolyte solution. These ions create an electric double layer that stores electrical charge in the capacitor. The double layer permits the capacitor to store energy and supply it to the circuit when required.

The 477RZM016M1013 aluminum electrolytic capacitor is a dry type capacitor meaning it does not require any additional lubricant or coolant, as it does not require active cooling. It has a maximum operating temperature of 105°C and is well-suited for use in a wide range of applications, such as power supplies, audio systems, and motor drives.
