Problems solved by technology
[0002] High-power flat common-mode inductors are generally used in high-current, high-power switching power supplies. Such applications generally require inductors with large inductance and low temperature rise to adapt to the working process of high-power heating. In the prior art, such The high-power and high-current inductors generally have a large volume and cannot meet the flat installation requirements.

Embodiment Construction
[0014] Such as figure 1 , figure 2 As shown, the present invention comprises base 1 and pin 2, and the bottom surface and top surface of described base 1 are circular, and described base 1 is made of epoxy resin; Described pin 2 has 10, is divided into two groups, Symmetrically installed on the side of the base 1. The pins 2 are bent to closely fit the base 1 according to the arc of the side of the base 1 .
[0015] Depend on image 3 It can be seen that there is a circular hole in the center of the base 1 .
[0016] The characteristics of the present invention are: high initial magnetic permeability, high saturation magnetic induction intensity, stable temperature compared with ferrite (which can be understood as small temperature rise), and relatively flexible frequency characteristics, because of high magnetic permeability, very small can make a large The sense of volume, the adaptation frequency is relatively wide.
[0017] What is described above is only a preferred...

The invention discloses a high-power flat common mode inductor. The high-power flat common mode inductor comprises a base and ten pins, wherein the bottom surface and the top surface of the base are circular, and the base is made of epoxy resin; the ten pins are divided into two groups, and are symmetrically mounted on the side surfaces of the base; the pins are bent, and are tightly attached to the base according to arcs of the side surfaces of the base; and a circular hole is formed in the center of the base. In the high-power flat common mode inductor, because of the existence of the circular hole in the base, the high-power flat common mode inductor can be directly mounted on a circuit board without using any additional clamp or other tools. The inductor disclosed by the invention is sufficiently low in height, and can guarantee the flat requirement of products. The high-power flat common mode inductor is flexible in structure, so that the adaptability is good, and the processing technology is changed, namely different requirements can be met.
Description
technical field [0001] The invention relates to electrical equipment, in particular to a high-power flat common-mode inductor. Background technique [0002] High-power flat common-mode inductors are generally used in high-current, high-power switching power supplies. Such applications generally require inductors with large inductance and low temperature rise to adapt to the working process of high-power heating. In the prior art, such High-power and high-current inductors generally have a large volume and cannot meet the requirements of flat installation. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a high-power flat common-mode inductor. [0004] Technical scheme of the present invention is as follows: [0005] A high-power flat common-mode inductor, including a base and pins. The bottom and top surfaces of the base are circular, and the base is made of epoxy resin; there are 10 pins, divided into two groups, s...
