Abstract:
A multilayer noise filter, comprising:a multilayer unit including a plurality of coil conductors and a plurality of insulating layers stacked on each other in a stacking direction, a coil which is defined by connecting said coil conductors in series and which extends in an axial direction, and a capacitor having at least a pair of capacitor conductors and an insulating layer stacked on each other in said stacking direction;at least one external input electrode and at least one external output electrode which are connected to said coil and which are disposed on a pair of opposed surfaces of said multilayer unit such that the external input and output electrodes are substantially perpendicular to the stacking direction of said multilayer unit and the axial direction of said coil;a resistor arranged to connect said external input and output electrodes, said resistor having substantially an elongated strip shape and disposed on substantially an entire length of at least one surface of said multilayer unit other than the pair of surfaces on which said input and output electrodes are disposed, said resistor being arranged to be substantially parallel to the stacking direction of said multilayer unit and the axial direction of said coil, and said resistor being electrically connected in parallel to each of said coil conductors.
