Abstract
The utility model relates to a novel manganese-zinc ferrite chip magnetic core which comprises at least one chip magnetic core body, wherein an insulating layer covers an electrode part of the chip magnetic core body, a silver layer used for attaching a metal electrode to the chip magnetic core body is arranged on the insulating layer, a nickel layer used for protecting the silver layer is electroplated on the silver layer, and a tin layer used for being welded on a circuit board is electroplated on the nickel layer. The novel manganese-zinc ferrite chip magnetic core with the structure improves the electrical properties on a power inductor or a transformer, and has a good using effect.
Description
Technical field
The utility model relates to manganese-zinc ferrite material (Mn-Zn Ferrite) paster core structure, can be used for the making of the components and parts such as chip inductor or transformer, especially a kind of can the raising has chip inductor or transformer performance now, expands a kind of novel manganese-zinc ferrite material paster magnetic core of this magnetic core range of application design.
Background technology
Chip inductor or the transformer of directly making electrode at present on magnetic core generally adopt the nickel-zinc ferrite material, do not use the manganese-zinc ferrite material.Main cause is that nickel core iron oxysome material surface resistivity is very high, generally reach several megohms centimetre (Ω cm), and the surface resistivity of manganese-zinc ferrite is lower, generally at thousands of ohmcms (Ω cm), differ general 1000 times, so if directly make electrode on manganese-zinc ferrite material magnetic core, can make the resistance between two electrodes very little, as be made into inductance or transformer, can produce larger electric energy loss, so existing also do not have producer to design in this way production.But the electrical property of manganese-zinc ferrite material on power inductance or transformer will be far superior to nickel core iron oxysome material, if overcome defects, the manganese-zinc ferrite material is applied on power inductance or transformer, will greatly improve the performance of product.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of novel manganese-zinc ferrite material paster magnetic core, its project organization is reasonable, electrical property is strong and can enhance product performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel manganese-zinc ferrite material paster magnetic core; the paster magnetic core array that comprises at least one; be coated with insulating barrier on the electrode part of described paster magnetic core array; be used for the lower manganese-zinc ferrite material of conductance is carried out insulation processing; insulating barrier is provided with for the silver layer that metal electrode is sticked on the paster magnetic core array; be electroplate with the nickel dam for the protection of silver layer on silver layer, be electroplate with on nickel dam be used to the tin layer that is welded on circuit board.
Described paster magnetic core array material is manganese-zinc ferrite, and manganese-zinc ferrite is MnFe
