Title: Noise filter
IPC: H03H7/06
Filed: 2002-09-11
Abstract: A noise filter 10 of the present invention includes an inductor 71 and a resistor 11 connected in parallel with each other. A power supply frequency current bypasses the resistor 11 but passes through the inductor 71. A high frequency noise current including a resonance frequency current, on the other hand, bypasses the inductor 71 but is dissipated at the resistor 11. Therefore, the noise filter 10 does not accumulate noise power and so does not suffer from a problem due to power releasing. The resonance frequency current caused by combination of inductance of the inductance and earth capacitance in the noise filter 10 is also dissipated at the resistor 11, thus giving rise to no problem of its own. <IMAGE> <IMAGE>
