Abstract

An electromagnetic component including a multi-layer coil structure embedded in a molded body is disclosed. Each layer of the coil structure has a loose middle segment, two slim end segments overlapping each other with a spacing therebetween, and tapered neck segments respectively connecting the loose middle segment with the two slim end segments.

Description

Technical field [0001] The invention relates to an electromagnetic device and its coil structure. Background technique [0002] As those skilled in the art know, in the past, electromagnetic devices such as inductors or choke coils were usually made by winding conductors or wires, such as copper wires coated with insulation, around a cylindrical core. This electromagnetic device is generally designed as a surface mount device (SMD) structure suitable for surface mount technology. [0003] In recent years, with the development of electronic components toward smaller volumes and higher performance, the demand for smaller-sized and high-performance coil devices has increased. In addition, the efficiency of the above-mentioned coil device can be determined from its saturation current (I sat ) And DC resistance (DC resistance, DCR). However, with the current coil device structure, it is very difficult to further reduce its size and volume. [0004] Therefore, there is still a need for ...
