The larger the film capacitor capacity, the better

        Due to the excellent performance and appropriate unit price of film capacitors, they are widely used in electronics, home appliances, telecommunications, electric power, electrified railways, hybrid vehicles, wind power, solar power and other industries, becoming indispensable to promote the upgrading of these industries Electronic component. When buying film capacitors, some people who are not too experienced will have some problems: the choice of film capacitor capacity is not appropriate. Some users feel that the larger the capacitor capacity is, the better. When choosing, choose the largest capacity as much as possible instead of capacity. Little, is this really correct?

        Many people believe that according to the principle of capacitors, when choosing a film capacitor, the larger the capacitance, the better. Although this statement is reasonable, we must know that under the current technology, the larger the capacitance, the larger the volume of the capacitor, which will take up more space. In some electronic products such as mobile phones Space is very important. It is not worthwhile to waste space because of wrong selection of capacitors with too large capacity.

        Moreover, the larger the capacity and the larger the volume will also affect the heat dissipation. Poor heat dissipation is bad for film capacitors or appliances. Also, in general, the larger the capacity of the capacitor of the same model, the more expensive it is. We have to choose the right one instead of the expensive one. The right one is good. Therefore, we have to choose film capacitors according to the needs of the overall circuit, and just choose a capacitor that can meet the needs of the circuit. There is no need to blindly pursue a large capacity.
