Structure of film capacitor

Film capacitors are also called plastic film capacitors. It uses plastic film as the dielectric. Some main characteristics of film capacitors in application: Non-polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), dielectric loss correction based on the above advantages, thin film capacitors are widely used in analog circuits. Especially in the part where the signal is connected, capacitors with good frequency characteristics and extremely low dielectric loss must be used to ensure that the signal is transmitted without too much distortion. Among all plastic film capacitors, the characteristics of polypropylene (PP) capacitors and polystyrene (PS) capacitors are the most significant.

Application of film capacitors

1 DC voltage application characteristics 1.1 Rated Voltage (VR) The rated voltage is defined as: within the rated operating temperature range (Tmin ~ TR), the maximum continuous DC voltage that the capacitor can withstand. It is related to the dielectric material and the thickness of the diaphragm. 1.2 Relationship between maximum DC voltage and temperature The temperature range category of the capacitor is given-the upper and lower ambient temperature values (Tmin ~ Tmax) of the capacitor can continue to work normally. Within this range, a rated temperature (rated temperature TR) under which the capacitor can work continuously under VR is defined. This voltage value depends on the dielectric material of the capacitor. Generally, for thin film capacitors:
