Radio frequency choke
TLDR
In this paper, a magnetic core is arranged in portions that may be secured around a cable so as to impede the flow of common-mode high frequency current, and the portions are aligned by clamps and secured by a strap.Abstract:
A magnetic core 1 is arranged in portions that may be secured around a cable 5 so as to impede the flow of common-mode high frequency current. The portions are aligned by clamps 2 and secured by a strap 3. A number of cores may be assembled together to provide increased impedance.read more
