CF series ferrite cores are intended to be set up on round cable to suppress high-frequency noises. CF series core consists of two halves of ferrite mounted within plastic casing whose two parts are fixed by latch. Core’s construction provides simplicity of assembly and disassembly on cable to be protected.
CF series cores may be successfully used in different power and signaling applications in input and output circuits of household and industrial electronics – for example, of pulse power supplies, monitors, fax machines, TV sets. In applications requiring large values of impedance, necessary values may be obtained by passing several turns of cable through CF core.

Impedance vs Frequency Dependency
Impedance vs frequency dependency for CF series ferrite cores:
Table data and impedance-frequency dependency graphs shown above are measured in wire section having a diameter of 1 mm and a length of 10 cm and passing through corresponding core of CF series. In practical applications of using other cables, real frequency dependencies may differ from specified above.
