<p><P>PROBLEM TO BE SOLVED: To sufficiently reduce high frequency noise in each of a plurality of frequency bands, such as a frequency band of medium wave broadcasting and a frequency band of FM broadcasting, while suppressing increases in the number of components used and in the number of connection points. <P>SOLUTION: A high frequency noise filter for an on-vehicle apparatus includes: a linear conductor 13 interconnecting an upstream terminal 11 and a downstream terminal 12; a first capacitor 14 comprising a self-resonant capacitor and having one end electrically connected to a first connection point P1 on an electrical conductor and the other end capable of being grounded; and a second capacitor 15 comprising a self-resonant capacitor different in electrostatic capacity from the first capacitor and having one end electrically connected to a second connection point P2 on the electrical conductor and the other end capable of being grounded. A ringed ferrite core surrounding the electrical conductor is disposed between the connection points. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
