B43890A5686M000

Aluminum electrolytic capacitors are a variety of capacitors that are widely used in electronic circuits. The B43890A5686M000 is a type of aluminum electrolytic capacitor.

Construction

The B43890A5686M000 is a non-sealed aluminum electrolytic capacitor. It has a cylindrical construction with two aluminum electrodes, a can, and a sleeve. The metal can provides mechanical strength and the sleeve maintains the environmental tightness of the component. The two electrodes are placed inside the can and are separated by an electrolyte-saturated paper. The paper absorbs humidity and therefore should be kept away from moisture sources.

Application field

Aluminum electrolytic capacitors are mainly used in various types of electronic equipment such as radios, TVs, and computers. The B43890A5686M000 is mainly used in applications that require a high capacitance-to-volume ratio. Examples include power supplies, motor control, and switching power supplies.

Working principle

The working principle of the B43890A5686M000 is based on Faraday’s law of electrolysis. The capacitor consists of two electrodes, a positive one and a negative one, which are separated by an electrolyte-saturated paper. When voltage is applied to the electrodes, a current begins to flow between them, causing the electrolyte to form an oxide film on the surface of the electrodes. This oxide film acts as a barrier to charge, thereby forming a capacitor. As a result, the capacitor can store and release energy when needed.

Conclusion

The B43890A5686M000 is an aluminum electrolytic capacitor that is widely used in many electronic devices. It has a cylindrical construction with two aluminum electrodes, a can, and a sleeve. It is mainly used in applications that require a high capacitance-to-volume ratio such as power supplies, motor control, and switching power supplies. The working principle of the capacitor is based on Faraday’s law of electrolysis.
