Round Ferrite core


Ferrite Cores

For all kind of round cables (Datac ables, coax cable, rotor control etc.). Very good suited for fighting interference of computers (keyboard or USB cable)... some PCs just can't stand the HF power.
Depending on the situation to be installed at either end of the cable. A selecteion of ferrite cores is a must for every DXpedition!

Of course you can try to build a common mode filter with these cores, but you will need several cores on the cable (at least for shortwave). If you are looking for ready made common mode filters, check our article 11368, right here.
