Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a film capacitor and its automatic production equipment and method. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. According to the type of plastic film, it is called polyethylene capacitor (also called Mylar capacitor), polypropylene capacitor (also called PP capacitor), polystyrene capacitor (also called PS capacitor) and polycarbonate capacitor. Film capacitors are excellent capacitors due to their many excellent characteristics. Its main characteristics are as follows: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Based on the above advantages, film capacitors are widely used in analo...
