FH Series Cores (Transfluxors)
FH series multi-aperture cores (transfluxors) are intended to protect data transmission links against electromagnetic noises propagated via plug-in connectors. On using, FH series transfluxor is put on terminals of connector.
High specific resistance of NiZn noise suppressing ferrite prevents a close of current-carrying legs of connector to ferrite transfluxor.

Impedance vs Frequency Dependency
Impedance vs frequency dependency for FH series ferrite cores:
Table data and impedance-frequency dependency graphs shown above for FH series ferrite transfluxors are for information only and are measured in wire section having a diameter of 0. 4 mm and a length of 10 cm and passing through upper left aperture of corresponding FH series core. In practical applications of really used plug-in connectors, frequency dependencies may differ from specified above.
