The inductor element is provided with a base on the side close to the circuit board. The coil terminals of the coil are inserted into the positioning holes on the base, and each coil terminal is extended out of the base. Since the positioning holes are directly opposite to the pads on the circuit board for mounting the inductor element, when the coil terminals extending out of the base are aligned one by one with the pads placed on the circuit board, after one of the coil terminals is welded on the pad, the remaining coil terminals are aligned one by one with the pads on the circuit board.

Whether during transportation or use, the vibration cannot be eliminated quickly, which will cause damage to the internal components of the common-mode inductor. Therefore, the purpose of the utility model is to increase the service life of the common-mode inductor by providing a shock-absorbing component. Utility Model Content
