Abstract
The invention discloses an organic thin-film capacitor. The organic thin-film capacitor comprises a capacitor core and a flame-retardant insulating material encapsulation layer outside the core, and also comprises two parallel leading wires on one side of the capacitor core, wherein the capacitor core is formed by rolling a metallized film serving as a medium and an electrode; the metallized film is a zinc-aluminum metalized film; the zinc-aluminum metalized film consists of a polypropylene base film, and a metal zinc layer and a metal aluminum layer formed through vapor deposition on one side; the zinc-aluminum metalized film is 4-5mu m in thickness and the width*margin is 30*2.5; the flame-retardant insulating material encapsulation layer is made of flame-retardant epoxy resin. Therefore, the capacitor has the advantages of high capacity, high stability, good electrical performance, high temperature resistance, small size and good self-healing property.
Description
Technical field
The present invention relates to electronic devices and components field, particularly relate to a kind of organic film condenser.
Background technology
Film capacitor does medium with organic plastics film, does electrode, made by winding method with metal forming or metallized film, wherein with polyester film medium and polypropylene screen media applications the widest.
Namely metallized film capacitor is replace metal forming as electrode in the surperficial evaporation layer of metal film of organic film, because the thickness of layer of metallized film is much smaller than the thickness of metal forming, therefore after winding, volume is also much little than type metal foil type electric capacity volume.But the stability of metallic film capacitor is not as good as type metal foil type electric capacity, bearing great current ability is also more weak, generally can not use as large value capacitor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of organic film condenser, has the self-healing performance that capacity is large, good stability, electrical property are excellent, high temperature resistant, volume is little and good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of organic film condenser, comprise electric capacity core body and the outer flame-retardant insulating material encapsulated layer of core body, also comprise two, the electric capacity core body side lead-in wire be parallel to each other, described electric capacity core body does medium by metallized film and electrode is curling, described metallized film is zinc-aluminium metallized film, described zinc-aluminium metallized film is by the metal zinc layers of polypropylene basement membrane with one side evaporation, metallic aluminum forms, the thickness of described zinc-aluminium metallized film is 4-5 μm, width x stays limit to measure as 30x2.5, described flame-retardant insulating material encapsulated layer adopts fire retarding epoxide resin.
In a preferred embodiment of the present invention, the thickness of described polypropylene basement membrane is 2.5-3 μm.
In a preferred embodiment of the present invention, on described polypropylene basement membrane, the metal zinc layers of evaporation and the gross thickness of metallic aluminum are 1.5-2 μm.
In a preferred embodiment of the present invention, described lead-in wire adopts CP wire.
The invention has the beneficial effects as follows: electric capacity core body by zinc-aluminium metallized film do dielectric medium and electrode roll around, the thickness of this zinc-aluminium metallized film is 4-5 μm, width x stays limit to measure as 30x2.5, this condenser capacity is stablized and has tolerance big current ability; Lead-in wire adopts CP wire, has good solderability; Employing fire retarding epoxide resin is encapsulated, and improves capacitance and the electrical strength of capacitor, and can improve partial discharge performance and heat resistance.
