What is aluminum electrolytic capacitors?The aluminum electrolytic capacitors are made of aluminum cylinder, which is provided with a liquid electrolyte, which is inserted into a curved aluminum strip to make a positive electrode and the capacitor is made of aluminum electrolytic capacitor. It is a kind of general electrolytic capacitor with good electrical properties, wide application range and high reliability.
The capacitor is a kind of energy storage element, which is used in the circuit for tuning, filtering, coupling, bypass, energy conversion and time delay. A capacitor is usually called a capacitor. According to its structure, it can be divided into three kinds of fixed capacitor, semi - variable capacitor and variable capacitor.
The aluminum electrolytic capacitors are kind of general electrolytic capacitor with good electrical properties, wide application range and high reliability.
The aluminum electrolytic capacitors made of aluminum cylinder, which is provided with a liquid electrolyte, which is inserted into a curved aluminum strip to make a positive electrode.
The core of aluminum electrolytic capacitors is made up of the anode aluminum foil, the backing paper of the electrolytic solution, the cathode aluminum foil, and the natural oxide film.After leaching electrolyte with aluminum shell and cover up closed form an electrolytic capacitor containing core. In general, aluminum electrolytic capacitors have a plastic casing outside the aluminum shell. The color of the casing is colorful, it is not only beautiful, but has the specific meaning.
The characteristics of the aluminum electrolytic capacitor is that its capacity is big
, but the leakage is large, the error is large, the stability is poor, it is commonly used for AC bypass and filter, it is also used for signal coupling. Electrolytic capacitors have positive and negative points, the use of, we can not put it back.
In short, aluminum electrolytic capacitors are usually the lowest cost option. However, you need to determine whether the disadvantages will adversely affect the application. You need to work through its temperature, consider the length of its life.In addition, you should also properly reduce the rated voltage, so that you can achieve the minimum operating temperature, thus obtaining the maximum service life.
