COMMON MODE FILTER

摘要

PROBLEM TO BE SOLVED: To provide a common mode filter including first and second coil electrode patterns to further improve insertion loss characteristics.SOLUTION: The common mode filter includes: first and second coil electrode patterns formed at an upper layer and having patterns alternately disposed; and first and second coil electrode patterns formed at a lower layer and having patterns alternately disposed. The outermost pattern of the upper layer and the outermost pattern of the lower layer are coil electrode patterns having the same order.
