Choose film capacitors to distinguish metallized film and metal foil

Nowadays film capacitors have been integrated into our lives, everyday household appliances, large industrial electronics, and film capacitors. It has a strong momentum in the capacitor industry and a large market demand. Therefore, you can play its role by purchasing film capacitors suitable for your own products.

Most of the film capacitors are polypropylene capacitors, and a metal film is applied on the outside. This film functions as an electrode, so it is necessary to distinguish between metallized film and metal foil when selecting. In practical applications, they differ greatly. Metallized film capacitors are more suitable for the needs of some small electronic products and equipment, and their volume is much smaller than that of metal foil.

When purchasing film capacitors, consider the actual voltage usage and some requirements for derating, so as not to cause some accidents. When the capacitor is in use, the current generates heat to the capacitor. If the heat is too high, the capacitor will heat up and damage the capacitor. Therefore, it is very important to choose the right film capacitors, and the application is free and long-lasting.
