Is it better to increase the film capacitor capacity?

Due to the excellent performance and suitable unit price of thin film capacitors, it has been widely used in many industries such as electronics, home appliances, communications, electric power, electrified railways, hybrid vehicles, wind power generation, solar power generation, etc., and has become an indispensable factor in promoting the upgrading of these industries. Electronic component. When buying thin film capacitors, many users choose the wrong film capacitor capacity. Some users feel that the larger the capacitance, the better. When choosing, try to choose as large a capacity as possible, not a small one. Is this really correct?

Many people think that according to the principle of capacitors, when selecting film capacitors, the larger the capacitance, the better. Although this statement is reasonable, we must know that under the current technology, the larger the electric capacity, 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 the location because of wrong selection of capacitors with large capacity.

Moreover, the larger the capacity, the larger the volume, and the greater the heat dissipation. The poor heat dissipation is not good for film capacitors or electrical appliances. What's more, in general, the larger the capacity of the same type withstand voltage, the more expensive it is. We have to choose the right one, and the right one is the right one. Therefore, we have to choose film capacitors according to the needs of the overall circuit, and choose capacitors that can meet the needs of the circuit. There is no need to blindly pursue large capacity.
