Aluminum electrolytic capacitors are the most widely used types of capacitors. They are most commonly used in power supplies, DC-DC converters, PWM circuits, and timing circuits. The EEE-FK1V390SR is one of the aluminum electrolytic capacitors available. It is a high-voltage, non-polarized capacitor with a maximum voltage rating of 390V, and a capacitance range of 1μF to 220μF. It is mainly used in motor start-up circuits, audio frequency circuits, communication circuits, and machine power circuits.

The working principle of the EEE-FK1V390SR is based on the physical phenomenon known as “electrolysis”. This occurs when two electrodes, placed in an electrolyte, are supplied with electric current. The current causes ions in the electrolyte to move towards one of the electrodes, where they are deposited, forming a thin film. This thin film acts as a dielectric, and increases the capacitance of the capacitor.

The EEE-FK1V390SR is constructed of an anode, a cathode, and an electrolyte. The anode is made of aluminum, which serves as the collector of the capacitor. It is then coated with a thin oxide layer, which serves as the dielectric. The cathode is made of tin-plated copper, which acts as the collector of the capacitor. The electrolyte is a solution of potassium hydroxide. This solution completes the electric circuit and facilitates the flow of ions in the electrolyte.

The main application areas for the EEE-FK1V390SR are motor start-up circuits, audio frequency circuits, communication circuits,and machine power circuits. As a motor starting capacitor, it is used to reduce the inrush current at start-up, which helps to reduce the risk of damage to the motor. In audio frequency circuits, it is used as a bypass capacitor, which helps to reduce noise and hum. In communication circuits, it is used as a decoupling capacitor, which helps to prevent high-frequency interference from affecting other components in the circuit. Finally, in machine power circuits, it is used as a filtering capacitor, which helps to reduce the ripple voltage in the power supply.

The EEE-FK1V390SR is a versatile and reliable aluminum electrolytic capacitor, with a wide range of applications. It is ideal for use in motor start-up circuits, audio frequency circuits, communication circuits, and machine power circuits. As a high-voltage, non-polarized capacitor, it is perfect for environments where space is limited and a large capacitance value is needed.
