A high-voltage film capacitor with an inductive series structure and a manufacturing method thereof relate to an electronic component and the manufacturing method. The capacitor is formed by leads, a capacitor core and a body. The capacitor core comprises: dielectric layers, a metalized film and electrodes. There are three layers of the dielectric layers and one electrode is arranged between each two layers of the dielectric layers respectively. The dielectric layers, the metalized film and the electrodes are wound so as to make the capacitor core, wherein the metalized film is the outside piece. Inner ends of the two leads are connected with the electrodes respectively and outer ends of the leads are led out of the body. The manufacturing method comprises the following steps: (1) winding: winding the dielectric layers, the metalized film and the electrodes so as to make the capacitor core; welding the leads on the electrodes and leading out during a winding process; (2) making a bench; (3) hot pressing; (4) encapsulating, printing and testing. By using a current energy-saving lamp with small power, an operation of starting a capacitor is complex; pollution is existed during a metal spraying process; a width of the electrode is small and there are many other problems. By using the capacitor and the method of the invention, the above problems can be solved.
Description
technical field [0001] The invention relates to an electronic component and a manufacturing method. In particular, it relates to a high-voltage film capacitor with an inductive series structure and a manufacturing method. Background technique [0002] From the analysis of film capacitors sold in the international and domestic markets, miniaturized capacitors that can be used in high-voltage applications and have high capacity and precision are the first choice for low-power energy-saving lamps in the future, but as starting capacitors, only CBB81 structure and CL11 inductive capacitors can meet the requirements. However, CL11 has a foil electrode structure, has no self-healing properties, and has low high-voltage reliability; and it is a single capacitor, which has great limitations in improving the withstand voltage. The CBB81 structure can meet the requirements, but the utilization rate of electrodes is low, the process is complicated, the cost is high, the lead-out of go...
