Abstract
The utility model discloses a chip inductor, including a body, a coil, two magnetic conductive plate, both ends electrode and a fin, this coil, two magnetic conductive plate all inlay the shaping with the body with the both ends electrode and are in the same place, and the coil lies in that this is internal, and two magnetic conductive plate expose the upper and lower surface of body respectively and lie in the coil respectively directly over under with, and this both ends electrode wraps up the both ends of body respectively, two pins of coil respectively with both ends electric connection, this fin covers in the surface of body, the fin is isolated with the both ends electrode, the apparent height of fin is less than the apparent height of termination electrode. Through being provided with the fin for the heat that this product produced can in time dispel the heat, guarantees the performance of product, and this product has excellent features such as can being able to bear or endure heavy current, high -power, high energy storage, high impedance, noiseless, high saturation magnetic flux density, moreover small, light in weight, the reliability is high, the shock resistance is strong.
Description
Technical field
The utility model relates to inductance art, refers in particular to a kind of chip 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 there is easily heating in current SMT Inductor, the problem that heat can not leave in time, causes product serviceability to decline, and therefore, is 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 chip inductor, and it effectively can solve the problem of existing chip inductor radiating effect difference.
For achieving the above object, the utility model adopts following technical scheme: a kind of chip inductor, includes a body, a coil, two magnetic conduction sheets, two end electrodes and a fin; This coil, two magnetic conduction sheets and two end electrodes 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 fin is covered in the outer surface of body, and fin and two end electrodes completely cut off, and the apparent height of fin is lower than the apparent height of termination electrode.
Preferably, described body is metallic magnetic powder die-casting body.
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, 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.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
