ABSTRACT:
A transmission line type noise filter, which is connectable between a direct current power supply and an electrical load component to pass a coming DC current while attenuating a coming AC current, includes a first conductor, a dielectric layer, a second conductor as a cathode, a first anode (12), and a second anode. The first and the second conductors and the dielectric layer serve as a capacitance forming portion. The thickness of the first conductor is selected to substantially restrict temperature elevation of the first conductor, which is caused by DC direct current flowing in the first conductor.
