Introduction to Aluminum Electrolytic Capacitors and Its Application Field and Working Principle

Aluminum electrolytic capacitors are one of the most commonly used capacitors in the world and have a wide range of applications in electronics and electrical engineering. It is used for filtering, buffering, decoupling, and controlling impedances. Aluminum electrolytic capacitors are also referred to as "electrolytic caps", "electrolytics", "aluminium electrolytic capacitors", and "electrochemical capacitors". The most common type of electrolytic capacitor used today is a cylindrical, solid-aluminum outer can, with an electrolyte solution and two aluminum electrodes. The inner electrode, or anode is the positive electrode, and the outer layer is the negative electrode, or the cathode. These are connected to an electrolyte, usually a solution of sulfuric acid, potassium hydroxide, or organic solvents.

What is 450BXA15MEFCG412.5X25?

450BXA15MEFCG412.5X25 is an aluminum electrolytic capacitor manufactured by TDK Corporation. It is a snap-in, leaded aluminum electrolytic capacitor with an operating temperature of -55°C to 125°C. This capacitor has a broad frequency range of 0.2 to 50 kHz, and offers excellent ripple current capabilities. It offers a high ripple current rating and a long life of up to 1904 hours (90,000 hrs). It has a radial-lead-type construction and is a very good choice when a long life is required in an application.

Application Field

Aluminum electrolytic capacitors are used in a variety of electronic applications, including voltage regulation, power conditioning, signal processing, timing, and power controlled switching. They are commonly found in power supply systems, motor control systems, telecommunications systems, medical equipment, consumer electronics, automotive electronics, and industrial automation systems. Aluminum electrolytic capacitors are used in AC-DC rectification circuits, power supplies, motor control circuits, audio equipment, switching power supplies, communication systems, consumer electronics, automotive electronics, industrial automation systems, and in servo and microprocessor systems.

Working Principle

An aluminium electrolytic capacitor consists of two electrodes, an anode and a cathode. The electrodes are separated by a non-conductive dielectric electrolyte. The operation of the capacitor is based on the electrochemical principle. When a DC voltage is applied to the electrodes, a variably sized oxide layer forms on the anode and allows for the storage of electrons. Through the resistance of this oxide layer, which is also known as the capacitance of the device, electric energy is stored. The electric charge stored in the capacitor is proportional to the applied voltage. When the voltage is removed, the charge on the capacitor is slowly discharged. This gradually reduces the capacitance of the device until it reaches its minimum, capacitance value. The current-carrying capacity of the capacitor is called its equivalent series resistance (ESR).

Conclusion

Aluminum electrolytic capacitors are widely used in a variety of applications. They are used to provide signal conditioning, voltage regulation, power conditioning, switch mode power supplies, power control and timing. Aluminum electrolytic capacitors are one of the most common types of capacitors and offer excellent stability and long life. 450BXA15MEFCG412.5X25 is an aluminum electrolytic capacitor manufactured by TDK Corporation. It offers a broad frequency range of 0.2 to 50 kHz, and a long life of up to 90,000 hours.
