Pagal plastikinės plėvelės tipą jie skirstomi į: polietileno kondensatorius (dar vadinamus "Mylar" kondensatoriais), polipropileno kondensatorius (dar vadinamus PP kondensatoriais), polistireno kondensatorius (dar vadinamus PS kondensatoriais) ir polikarbonato kondensatorius.
The structure is the same as paper dielectric capacitors, and the dielectric is polyester or polystyrene, etc. Polyester film capacitor has high dielectric constant, small size, large capacity, better stability, and suitable for bypass capacitor. Polystyrene film capacitor, with low dielectric loss and high insulation resistance, but large temperature coefficient, can be used in high frequency circuits.
Wire-end classification
Film capacitor manufacturers can be divided into two categories: DC film capacitors are film capacitors working in circuits powered by DC power supply, which can be divided into four categories: general-purpose, suppression of electromagnetic interference from power supply, pulse and precision; AC film capacitors are film capacitors working in circuits powered by AC power supply, which are divided into motor starting operation, power Factor compensation, etc.
