ABSTRACT:
A multilayer noise filter includes a damping resistor which is arranged to control the distortion of the waveform of an output signal and eliminate a space required for installation of the damping resistor on a substrate upon which the filter is mounted. The axial direction of coils incorporated in inductor assemblies is substantially perpendicular to external input and output electrodes. One end of one coil is electrically connected to the external input electrode and one end of another coil is electrically connected to the external output electrode. The other ends of the coils are electrically connected to a resistor at different locations, respectively. The resistor connecting the external input and output electrodes is disposed on the top surface of a multilayer unit such that the resistor is substantially parallel to the stacking direction of the multilayer unit and the axial direction of the coils. In a capacitor assembly, a pair of capacitor conductors are arranged to face each other.
