Talk about the film material used by film capacitor manufacturers

Nowadays, technology is developing rapidly, and film capacitors are gradually used in many industries. The material of the film capacitor film naturally occupies an important position. Today's editor wants to take a look at the characteristics of film capacitors of different materials.

Film capacitors are commonly used in two materials: polypropylene film and polyester film, while others such as polystyrene film are less used. Next, we understand the characteristics of the two materials used by the film capacitor manufacturer.

Let me talk about the polyester film. The polyester film has high insulation resistance, good self-healing property, high volume ratio, stable electric capacity, positive temperature coefficient, wide operating temperature range and high dielectric constant. The polypropylene film has good high frequency performance (low loss), excellent self-healing property, high insulation resistance, high dielectric constant, low temperature coefficient and low medium absorption coefficient. The two films have their own lengths, so the capacitors produced by the two films have different coverage.
