Detailed description of the classification and characteristics of film capacitor(II)

Polyester film (terylene) capacitor

Polyester film has a large dielectric constant and good heat resistance. It can work between 120 and 130 C. The disadvantage is that the loss is large and the frequency varies greatly. This capacitor can replace the paper capacitor, and it works in DC and pulsating circuits. It is not suitable for working at high frequency.

Polystyrene film capacitor

The main features are high insulation resistance, low loss, high precision, small change of electrical parameters with frequency and temperature. The disadvantages are large volume and low working temperature (upper limit 70℃). The capacitor is mainly used in filtering, high frequency tuner and equalizer.

The classification of film capacitors is the same, and different types of capacitors have different effects. We want to classify a capacitor with film capacitor. These types of capacitors have different effects. We must have a thorough understanding of the capacitor so as to ensure that we are accurate in our selection, saving time and reducing unnecessary trouble. If you have any questions, you can consult us.
