What is the general capacitance of a capacitor? What are the factors that affect it?

by:GREEN TECH     2021-04-17

Capacitors are relatively common electronic components. There are many capacitor products on the market, and there are also many manufacturers specializing in the production of capacitors. Different manufacturers have different strengths. If you want to buy capacitors, you must understand the basic situation of capacitors, such as The size of the capacitance, then how large is the capacitance of the capacitor in general? What factors are affected by it?

1. Types of capacitors

The capacitance of a capacitor is generally large. Different types of capacitors are determined during production and design. This cannot be changed. For example, the capacitance of supercapacitors is very large, while the capacitance of general capacitors is limited. The type of capacitor depends not only on the design, but also on the material used.

2. The environment when the capacitor is used

How large is the capacitance of a capacitor? There are requirements for the environment when using capacitor products. The requirements for the environment include humidity, temperature, etc. If the humidity is too high, it will affect the service life of the capacitor and may affect the capacitance. If the temperature of the capacitor is too high, it will affect the service life of the capacitor.

3, the frequency of use of capacitors

Although the capacitance of capacitor products is fixed during production and design, in fact, if the capacitor is used for a long time, the service life of the capacitor will be shortened. Therefore, when using capacitors, they must be used correctly and not overused to avoid premature aging.

Generally speaking, the general capacitance of a capacitor is actually uncertain. Different types of capacitors have different capacitances, and the environment and frequency of the use of the capacitors will also affect the capacitance of the capacitors. When using the capacitor, be sure to use it in accordance with the instructions and precautions.
