Thin film capacitor capable of improving heat dissipation effect and manufacturing method thereof

The invention discloses a thin film capacitor capable of improving a heat dissipation effect and a manufacturing method thereof. The thin film capacitor comprises a capacitor body, a heat dissipation sleeve nested and attached outside the capacitor body, a mounting sleeve in threaded connection with the outer side of the lower end of the heat dissipation sleeve, and a shielding sleeve in threaded connection with the inner side of the upper end of the heat dissipation sleeve. A shell is arranged at the outer end of the capacitor body, and a capacitor inner core is arranged on the inner side of the middle part of the shell; a second connecting plug in threaded connection with the heat dissipation sleeve is arranged on the upper left portion of the heat dissipation sleeve, and the upper surface of the heat dissipation sleeve and the upper surface of the second connecting plug are the same horizontal plane. According to the thin-film capacitor capable of improving the heat dissipation effect and the manufacturing
