Abstract
It is master alloying ferrite material magnetic core that the utility model provides a kind of Novel iron silicon, iron sial; it comprises the magnetic core array of at least one, in the electrode part of described magnetic core array, is coated with insulating barrier, and insulating barrier outside is coated with silver layer; on silver layer, be coated with protection nickel dam, nickel dam is provided with tin layer.The beneficial effects of the utility model are: adopt the magnetic core of this kind of structure, improved the electrical property on power inductance or transformer, result of use is good.
Description
Technical field
The utility model relates to iron silicon, sendust ferrite material (Fe-Si alloy, Fe-Si-Al alloy) core structure, can be used for the making of the components and parts such as inductance or transformer, especially a kind ofly can improve the electric properties such as existing inductance or transformer saturation induction density, Curie temperature, be applied in circuit noise low, the high-temperature of resistance to high humidity, panel type is pressed into resistance to high-intensity mechanical shock, have increase face coat simultaneously, expand the design of this magnetic core range of application a kind of Novel iron silicon, iron sial be master alloying ferrite material magnetic core.
Background technology
Inductance or the transformer of directly on magnetic core, making at present electrode generally adopt nickel core iron oxysome material, do not use iron silicon, sendust ferrite material.Main cause is that nickel core iron oxysome material surface resistivity is very high, generally reach several megohms. rice (Ω .m), and iron silicon, the ferritic surface resistivity of sendust ferrite are lower, generally at thousands of ohm-meter (Ω .m), differ greatly, if so directly make electrode on iron silicon, sendust ferrite material magnetic core, can make the resistance between two electrodes very little, as be made into the words of inductance or transformer, can produce larger electric energy loss, so existing, also not have producer to design in this way production.But iron silicon, iron sial are main alloyed iron oxysome material, the electrical property on power inductance or transformer will be far superior to nickel core iron oxysome material, if overcome above-mentioned defect, iron silicon, sendust ferrite material are applied on power inductance or transformer, will greatly improve the performance of product.
Summary of the invention
The utility model, in order to overcome the problem of above-mentioned middle existence, provides a kind of Novel iron silicon, sendust ferrite material paster magnetic core, and its project organization is reasonable, electrical property is strong and can enhance product performance.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel iron silicon, iron sial are master alloying ferrite material magnetic core; it comprises the magnetic core array of at least one; in the electrode part of described magnetic core array, be coated with insulating barrier; insulating barrier outside is coated with silver layer; on silver layer, be coated with protection nickel dam, nickel dam is provided with tin layer.
Described magnetic core array material is that iron silicon, iron sial are master alloying ferrite.
Described silver layer sticks to metal electrode on magnetic core array.
Described magnetic core array is welded on circuit board by tin layer.
Described magnetic core array material is iron silicon, sendust ferrite, iron silicon, sendust ferrite are Fe-Si alloys, the solid solution of Fe-Si-Al alloy, there is the electric properties such as high saturated magnetic induction, high-curie temperature, be applied in circuit noise low, the high-temperature of resistance to high humidity, panel type is pressed into resistance to high-intensity mechanical shock, crystal grain is thinner, and close structure is often black.
The beneficial effects of the utility model are: adopt the magnetic core of this kind of structure, improved the electrical property on power inductance or transformer, result of use is good.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Reference numeral: 1-paster magnetic core array, 2-insulating barrier, 3-silver layer, 4-nickel dam, 5-tin layer.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of Novel iron silicon as shown in Figure 1, sendust ferrite material paster magnetic core; comprise that at least one material is the ferritic magnetic core array 1 of iron silicon, sendust; in the electrode part of paster magnetic core array 1, be coated with insulating barrier 2; on insulating barrier 2, be provided with for metal electrode being sticked to the silver layer 3 on paster magnetic core array 1; on silver layer 3, be coated with the nickel dam 4 for the protection of silver layer 3, nickel dam 4 is provided with for being welded on the tin layer 5 on circuit board.
The manufacture method of a kind of Novel iron silicon of the present utility model, sendust ferrite material paster magnetic core: be first coated with the resistant to elevated temperatures insulating barrier 2 of the special energy of one deck on the paster magnetic core array 1 of iron silicon, sendust ferrite material, its object is for the lower iron silicon of conductance, sendust ferrite material being carried out to insulation processing, and then coat successively silver layer 3, nickel dam 4, tin layer 5, thereby form the electrode of chip inductor or transformer.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
