Description
Technical field
The utility model relates to inductance art, refers in particular to a kind of paster high-frequency inductor.
Background technology
Inductor can be the element that magnetic energy stores electric energy conversion.The similar of inductor in transformer, but only has a winding.Inductor has certain inductance, and it only stops the change of electric current.If do not have electric current to pass through in inductor, then it stops electric current to flow through it; If there is electric current to flow through it, then circuit disconnect time it will attempt maintenance electric current constant.The various coils of inductor insulated conductor coiling are called inductance.Be coiled into a circle or multiturn to produce the electronic component of certain self-inductance with wire, often claim inductance coil or be called for short coil.Inductor is widely used in electronic circuit, for realizing one of the main element of vibration, tuning, coupling, filtering, delay, deflection.In order to increase inductance value, put forward high q-factor and reduced volume, in coil of being everlasting, insert magnetic core.Along with the develop rapidly of electronics and information industry, patch type electronic component is adopted in a large number, and SMT Inductor is exactly one of them.
But current SMT Inductor ubiquity radiating effect is bad, the problem that high frequency performance is not good, be necessary to improve current SMT Inductor.
Summary of the invention
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of paster high-frequency inductor, and it effectively can solve existing SMT Inductor and there is the problem that radiating effect is bad, high frequency performance is not good.
For achieving the above object, the utility model adopts following technical scheme: a kind of paster high-frequency inductor, includes a body, an iron core, a coil, two magnetic conduction sheets, two end electrodes, a thermal sensitive piece and a fin, this coil is sheathed on the lateral surface of iron core, this iron core, coil, two magnetic conduction sheets, two end electrodes and thermal sensitive piece are all together with body produced by insert molding, coil is positioned at body, two magnetic conduction sheets expose respectively body upper and lower surface and to lay respectively at directly over coil and immediately below, this two end electrodes wraps the two ends of body respectively, the two pins of coil is electrically connected with two end electrodes respectively, this thermal sensitive piece is in one end of iron core with wherein between a magnetic conduction sheet, this fin is covered in the outer surface of body, fin and two end electrodes completely cut off, the apparent height of fin is lower than the apparent height of termination electrode.
Preferably, described body is made up of epoxy resin layer and the metal bisque be coated on outside epoxy resin layer.
Preferably, described coil is made up of a copper cash and the insulating barrier be coated on outside this copper cash.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution: by being provided with fin, the heat that this product is produced can dispel the heat in time, radiating effect effectively strengthens, by being equipped with cored and two magnetic conduction sheets, the high frequency characteristics of product is strengthened, ensure the serviceability of product, this product has can the good characteristic such as resistance to big current, high-power, high energy storage, high impedance, noiseless, high saturation magnetic flux density, and volume is little, lightweight, reliability is high, shock resistance is strong.
