The difference between smd inductor and wire wound inductor

The difference between the smd laminated inductor and the wire wound inductor is mainly reflected in 5 aspects: the difference in production process: the wire wound smd inductor is based on the traditional wire wound inductor production process, which transforms the traditional plug-in inductor into a smd package. The volume of the inductor is reduced, and the installation and use are more convenient; the smd laminated inductor is made by multi-layer printing technology and laminated production process.

The difference in inductor performance: The smd laminated inductor has good magnetic shielding, high sintering density, and good mechanical strength, but the inductor accuracy and inductor  range are not as good as the winding smd inductor. In addition, the winding inductor has the advantages of high Q, low loss, and large current.

The difference in the price of inductor: Because of the difference in structure and process between smd laminated inductor and wire wound smd inductor, the production of laminated inductor is more difficult and the technical requirements are higher. Therefore, there are more defects, higher production costs, and higher prices. Winding inductor are expensive.

Other differences: The heat dissipation of the smd laminated inductor is better than that of the wire wound smd inductor. The smd laminated inductor and the wire wound smd inductor have 4 aspects in common, but the inductor production process, structure, performance and price the difference. In a nutshell, SMD laminated inductor cannot see the wire, and are better than SMD wire wound inductor in terms of anti-inductor  interference ability, heat dissipation, and installation space saving. However, wire wound inductor are better in current resistance and inductor production costs. Slightly better, at the same time the winding inductor has a higher ESR value than the smd multilayer inductor.
