Abstract
In a filter component with improved attenuation characteristics for common mode noise, an LC series resonance circuit disposed in each of a plurality of shunt circuits is connected at a first end to a first line and is grounded at a second end. The LC series resonance circuit disposed in each of the shunt circuits is grounded at a first end and is connected at a second end to a second line. With this configuration, the LC series resonance circuits resonate reliably so as to define attenuation poles. Accordingly, the resonant frequency of each of the LC series resonance circuits is set to be a frequency that effectively attenuates common mode noise.
