Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most widely used type of capacitors in all kinds of electronic equipment, due to its relatively low cost, simple design, ease of manufacturing, and easy repair. This type of capacitor is composed of a foil or metalized capacitor element, which is surrounded by an electrolyte solution. The capacitor element and electrolyte are held together by an aluminum can or case, and a plastic end cap.

The number 860080380027 is a specific type of aluminum electrolytic capacitor, which has a polypropylene film dielectric element and gives a low equivalent series resistance (ESR). The capacitor has a rated voltage of up to 85°C. Its application fields are mainly for smoothing, buffering, and power supplies in many types of electrical and electronic circuits.

Working Principle

The working principle of aluminum electrolytic capacitors is the same as any other capacitor: electrons are stored on the capacitive plate and discharged when a current flows through it. This type of capacitor is most frequently used for the purpose of Temporary Voltage Suppression, or TVS. This is used to quickly reduce an electrical voltage spike and protect against any type of power surge. The capacitor consists of an insulating film element and an electrode. When an electric field is applied, the electrostatic charged ions stored on the film element cause the ions stored on the electrode to move, resulting in a capacitance change. This change in capacitance affects the electric field, thus reducing the voltage.

Selection Guide:

When selecting the right aluminum electrolytic capacitor for an application, there are several factors to consider:

1. The working voltage of the electrolytic capacitor should match the voltage in the application.
2. The size and shape of the capacitor should fit the required space.
3. The type of dielectric should match the requirements of the application.
4. The ripple current rating of the capacitor should be higher than the expected ripple current.
5. The ESR value of the capacitor should be lower than the required value.
6. The temperature range of the capacitor should be wide enough for the application.

When selecting the right aluminum electrolytic capacitor, its important to pay attention to the above selection guide. If the requirements aren\'t met, it\'s likely that the capacitor won\'t perform as needed and might even fail.

Conclusion

Aluminum electrolytic capacitors are widely used in countless electronic devices for voltage buffering, smoothing, and power supplies. The number 860080380027 is a specific type of aluminum electrolytic capacitor, which has a high voltage and low equivalent series resistance rating. It is crucial to consider the selection guide when choosing the right capacitor for the application.
