Patent number: 10566947Abstract: A filter for both a differential mode and a common mode is provided. A filter for both a differential mode and a common mode according to an embodiment of the present invention comprises: a pair of series inductors having a plurality of coil patterns; two pairs of parallel capacitors connected to opposite ends of the pair of inductors, respectively; and a pair of series capacitors connected to the pair of inductors in parallel. Therefore, the filter can be used in both a common mode and a differential mode, and can remove noise without using an additional filter in an application having a comparatively high data processing speed.Type: GrantFiled: February 3, 2017Date of Patent: February 18, 2020Assignee: AMOTECH CO., LTD.Inventors: Jong Soo Kim, Jae Su Ryu, Yoon Ho Hwang
