Abstract

The invention discloses a wave-cut remaining edge type thin-film capacitor, which comprises a capacitor core 1 and a capacitor body 2. The capacitor core 1 is composed of four parts which are two layers of parallel thin-film dielectric 3, a metal coating electrode 4 located on the thin-film dielectric 3, a metal spraying layer on the surface of the metal coating electrode 4 and a lead 5 welded on the metal spraying layer. The right side of the metal coating electrode 4 and the right side of the thin-film dielectric 3 are both of a wave-shaped structure formed in a wave-cut manner. A remaining edge 6 is disposed between the right side of the metal coating electrode 4 and the right side of the thin-film dielectric 3. The invention has the beneficial effects of enhanced current resistance, low loss, safety and environmental protection, simple structure and high practicality.

Description

technical field [0001] The invention relates to the improvement of capacitors, in particular to a wave-cut and edge-cut film capacitor. Background technique [0002] The effective contact area between the gold-sprayed layer and the core metal film of ordinary capacitors is small, so that the adhesion between the gold-sprayed layer and the core is small, resulting in low mechanical strength and weak current resistance of the gold-sprayed layer of film capacitors. affect the life of the capacitor. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems and design a wave-cut and edge-cut film capacitor. [0004] The technical solution of the present invention to achieve the above object is a wave-cut edge-cut film capacitor, comprising a capacitor core 1 and a capacitor body 2, the capacitor core 1 is composed of two layers of film media 3 arranged in parallel, located The metal-plated electrode 4 on the metal-plated e...
