Abstract:
A winding-type capacitor package structure and a method of manufacturing the same are provided. The winding-type capacitor package structure includes a winding assembly, a package assembly, a conductive assembly, and a bottom carrier frame. The winding assembly includes a positive winding conductive foil and a negative winding conductive foil. The winding assembly is enclosed by the package assembly. The package assembly includes a casing structure and a filling body received inside the casing structure. The casing structure has an inner rough surface. The bottom carrier frame is disposed on a bottom portion of the casing structure. The filling body includes a plurality of layered structures, and each of the layered structure is connected between the winding assembly and the casing structure. Therefore, the filling body including the layered structures can be limited inside the casing structure through friction force provided by the inner rough surface.
