Description

An electromagnetic environment is growing worse above 1GHz due to a portable telephone's spreading and speeding up the clock frequency. Although it is difficult that the electromagnetic noise of a high frequency conducts easily, the noise is able to conduct a short distance, and the noise causes malfunctions. A common mode chock coil that influences hardly a transmission signal, is suitable for suppressing such a conducted noise in a lead wire. Then, application of the design technique which had been applied to the conducted noise of a low frequency was verified for the common mode chock coil which suppressed the conducted noise above 1GHz. Here, the used limit and the material condition demanded of this chock coil are described.
