FSB31-1, ID=1", RFI Range 1-300 MHz, Bulk Pack of 4
Also known as Big Clamp On. Very useful for AC/DC power, coax cable,
etc. Use multiple turns for best results or multiple chokes in series
(recommended for large amperage power cables). Always put +/- dc cables through the same ferrite filter so their fields cancel and the ferrite suppresses the common mode current on each cable.. Bulk pack of 4 - Best bulk rate.
