About the use of aluminum electrolytic capacitors Next, Shandong Hongbao Electronics will introduce you to the use of aluminum electrolytic capacitors.

The use of aluminum electrolytic capacitors and their production process, precautions Aluminum electrolytic capacitors are made of aluminum cylinders as negative electrodes, which are filled with liquid electrolytes, and are called aluminum electrolytic capacitors.

A capacitor is an energy storage element that is used in circuits for tuning, filtering, coupling, bypassing, energy conversion, and time delay. Capacitors are often referred to as capacitors.

Types and uses of aluminum electrolytic capacitors.

1. According to the structure, it is divided into three categories: fixed capacitors, variable capacitors and trimmer capacitors.

2. Classification according to electrolyte: organic dielectric capacitors, inorganic dielectric slag containers, electrolytic capacitors and air dielectric capacitors, etc.

3. According to the application, it is divided into: high-frequency bypass, low-frequency bypass, filtering, tuning, high-frequency coupling, low-frequency coupling, and small capacitors.

What material are aluminum electrolytic capacitors made of? Aluminum electrolytic capacitors are composed of aluminum foil (positive and negative), lead wire (positive and negative), rubber stopper, electrolyte, aluminum shell, and bushing. Aluminum foil is a formed foil covered with alumina; The old Xinming lead is composed of an aluminum tongue with an aluminum sliding and an iron-tinned CP wire; The electrolyte is generally a glycol solution of ammonium of weak acid; There are many types of casing, including PET and PVC (banned, but it is not excluded that there are crimes committed against the wind) and so on.

Aluminum electrolytic capacitor is a common capacitor, and its application principles include the following:1Choose the right capacitance and voltage level.

The capacitance value and operating voltage of aluminum electrolytic capacitors need to be selected according to the actual needs to ensure that the required circuit requirements are met. 2.Avoid reverse polarity connections.

Due to the polarity of aluminum electrolytic capacitors, it is necessary to pay attention to the connection direction of the positive and negative electrodes during use to avoid damage to the components or the circuit does not work due to the reverse polarity connection. 3.Controls the temperature of the capacitor.

The lifetime of aluminum electrolytic capacitors is closely related to temperature, and when the ambient temperature is higher than the specified temperature, its service life will be greatly shortened. Therefore, it is necessary to control the temperature of the capacitor so that it can operate normally within the specified temperature range. 4.

Pay attention to the frequency response of the capacitor. The frequency response of aluminum electrolytic capacitors is poor, which has certain limitations on the transmission of high-frequency signals. Therefore, when using aluminum electrolytic capacitors, it is necessary to select the appropriate capacitor type or take other corresponding measures to compensate according to the specific application situation to achieve better results.

To sum up, the application principles of aluminum electrolytic capacitors mainly include selecting the appropriate electric volt balance capacity and lack of hand voltage level, avoiding reverse polarity connection, controlling the temperature of the capacitor, and paying attention to the frequency response of the capacitor.

1. Generally speaking, if the voltage is determined, the larger the aluminum foil area, the larger the capacitor capacity;

2. The capacitance of the parallel plate capacitor is proportional to the dielectric constant, inversely proportional to the opposite area, and inversely proportional to the distance between the plates;

3. The dielectric constant is determined by the medium between the two plates;

4. If it is an aluminum electrolytic capacitor, because the medium is aluminum oxide, the cracked medium is thin, if the voltage is constant, the larger the aluminum foil area, the larger the capacity, so the capacity is basically determined by the aluminum foil area;

5. If it is a gold film capacitor, the medium is a thin film, the higher the voltage, the thicker the medium, so the capacity is not only related to the area of the aluminum foil, but also related to the thickness of the medium.

1. In general, if the voltage is determined, the larger the aluminum foil area, the larger the capacitor capacity;

2. The capacitance of the parallel plate capacitor is proportional to the dielectric constant, inversely proportional to the opposite area, and inversely proportional to the distance between the plates;

3. The dielectric constant is determined by the intermediary and closed matter between the two plates;

4. If it is an aluminum electrolytic capacitor, because the medium is aluminum oxide, the dielectric is thin, such as the greater the aluminum foil area and the larger the capacity under the condition of a certain voltage, so the capacity is basically determined by the aluminum foil area;

5. If it is a cracked gold film capacitor, the medium is a thin film, and the voltage is high, the thicker the medium, so the capacity is not only related to the area of the aluminum foil, but also related to the thickness of the medium.
