NOISE FILTER AND ELECTRONIC DEVICE INCLUDING THE SAME

摘要

The present invention relates to a noise filter for integrating a common mode noise filter and a normal mode noise filter, and to an electronic device including the same. The noise filter for preventing a noise on a power line or a ground line of a power circuit unit in the electronic device includes at least one coil connected to the power line and the ground line, a common core unit for preventing a common mode noise on the ground line which the coil coils around, and a normal core unit for preventing a normal mode noise on the power line and the common core unit. The present invention increases productivity and reduces manufacturing costs by integrating the common mode noise filter and the normal mode noise filter.
