1.一般corebead的“appliedfrequencyrange”這個規格遠比25Mhz~100Mhz小,如佳真(core-tech)的"K5A"材質:appliedfrequencyrange:0.1~1Mhz而阻抗--頻率特性卻是以25Mhz和100Mhz為參考的這是怎麼回事?2.corebead有感性和阻性之說,該怎樣區分和使用?
To suppress high frequency common mode radiation, we suggest ferrites with appropriate impedance characteristics. Since the impedance of the ferrites varies with frequency, at high frequency ferrites behave more like a resistor than an inductor. At high frequencies ferrites resistive losses can be used to fight radiation.
