NOVELTY - The utility model model claims a common mode inductor for inhibiting EMI noise, relating to the technical field of common mode inductor, comprising a support frame the inner side of the support frame fixedly mounted with an iron core, the outer wall of the iron core is provided with an EMI suppression common-mode inductance coil, the top of the support frame fixedly mounted with a radiating top plate, the bottom of the radiating top plate is fixedly connected with a heat collecting plate, two sides of the supporting frame are provided with a replacing mechanism, the bottom of the supporting frame is provided with a fire extinguishing mechanism under the EMI suppression common mode inductance coil, the replacing mechanism a plastic box the right side of the plastic box cavity is fixedly installed with an insulating plate. The utility model model absorbs the heat generated when the common-mode inductance coil is operated by the heat collecting plate and the graphene heat-absorbing rod, the heat is transmitted to the top of the radiating top plate through the radiating hole, the heat is quickly radiated by the reinforcing rib, It reduces the possibility that the EMI suppresses the damage of the common-mode inductance coil caused by the long-time operation in the high temperature environment.
