Abstract: A thin-film capacitor core that has a core body, a covering film and a sprayed metal coating provided at two ends of the core body to form electrodes. The covering film is wound around an outer circumferential surface of the core body; the covering film has a base film and a waterproof layer attached to the base film. A waterproof covering process for the thin-film capacitor core can be performed by means of winding using a winding machine for producing a core body, such that on the premise of ensuring production efficiency of the thin-film capacitor core, the moisture resistance of the thin-film capacitor core is improved. A thin-film capacitor loaded with the thin-film capacitor core, and a printed circuit board loaded with the thin-film capacitor are also provided.

Abstract: An electrode structure of a laminated metallization film capacitor includes at least two laminated metallization films. Each metallization film is further disposed with a plurality of metal-uncoated curved gap strips with a certain width on the plane of section of the laminated metallization film capacitor core to separate two adjacent metal coating units partially or totally. A center of the curved gas strip is concaved with a notch. Both sides of the notch form like misaligned shoulders. A projection forms opposite to the open of the notch; in two adjacent curve gap strips. An extreme point of the projection of one curve gap strip is disposed inside the notch of the other one in any event.
