Flat wire inductor is the inductor wound with flat enamelled copper wire. In this article ，I will introduce the definition and effect of flat coil inductor.
First of all, let me briefly introduce the current situation of this product in China. At present, factories producing such products in China have blossomed everywhere, accounting for half of the import volume of such products. Due to the competition among domestic flat coil manufacturers, the R & D or winding technology of flat coil in China has gradually become sophisticated and perfect, and the momentum of gradually replacing imported materials is becoming more and more obvious. Why did flat coil develop so rapidly in China in 7-8 years? From a few monopolies to a hundred. Let me explain in this article for you.
The Definition of Flat Wire Inductor
The flat coil inductor , which is composed of a coil part and a magnetic inductive base and a cover made of iron powder by die casting; Together, the coil part is a flat coil type wire, and the connecting leg parts at both ends are bent in the direction of conducting electricity with the external circuit, and an insulating cover is injected on the outer surfaces of the coil part and the leg part, and a part of the pin part is exposed as the connecting surface connecting with the external circuit, so that the pin part is preformed and formed together with the coil part, and the sleeve is placed in the magnetic inductive base.
Inductor Characteristics of Flat Coil
(1) Flat wire to bear big current
(2) Shielding inductor structure. Flat coil – the inductor of flat wire is mainly used at the output end because of its high current and low resistance.
(3) The same specification with low DC resistance
(4) to ensure the inductance reduced less when loaded with current
(5) Applicable to reflow SMT craft.
(6) This product is lead-free and conforms to the RoHS directive.
(7) It is suitable for DC to DC on power supply circuit of power supply, personal computers and other handheld electronic devices .
As a whole, the inductor of the flat coil has a flat structure, which increases the area volume ratio of the product. Therefore, from the aspect of heat dissipation of the magnetic core, the flat coil is the best treatment method, which is more convenient for heat dissipation than the round enameled wire.
