The role of capacitors

In a DC circuit, a capacitor is equivalent to an open circuit. Capacitors are components that store electrical charge and are one of the most commonly used electronic components. This has to start with the structure of the capacitor.

What is a variable capacitor?

Variable capacitors are capacitors whose capacitance can be adjusted within a certain range. Variable capacitors can be divided into fine-tuning variable capacitors, single-connected variable capacitors, double-connected variable capacitors, and quad-connected variable capacitors according to different structures.

What is an electrolytic capacitor?

Electrolytic capacitors are polar capacitors, and their pins are clearly divided into positive and negative poles. When using, the polarity of the pins cannot be reversed.

Capacitor coupling function

The impedance of the capacitor to the AC signal is small, which can be regarded as a channel, and the impedance to the DC signal is large, which can be regarded as an open circuit.

What are the types of capacitors

A sintered tantalum block is used as the positive electrode, and solid manganese dioxide is used as the electrolyte. The temperature characteristics, frequency characteristics and reliability are better than general electrolytic capacitors, especially the leakage current is extremely small, the storage performance is good, the life is long, the capacity error is small, and the volume is small, and a great capacitance-voltage product can be obtained per unit volume.

What are the working principles of module capacitors?

Capacitors are made of plates at both ends and an insulating dielectric (including air) in the center. After energization, the plates are charged to form a voltage (potential difference), but because of the insulating material in the center, the entire capacitor is non-conductive.
