Mix 31 Ferrite Snap On Combo pack (RFI Suppression range is 1-300 MHz)
The Ferrite Snap On Combo Pack is a convenient solution for troubleshooting RFI/EMI with various diameter cables ranging from 1/4″ to 3/4″ for use as either single turn or multiple turn ferrite chokes.
The snap on chokes are useful for RF coax, AC/DC power cables, and device interconnection cables.
Always use a snap on ferrite with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turns in series).
Included in the combo pack are our most popular snap on sizes as follows:
FSB31-1/4 – 1/4″ ID – 6 pieces
FSB31-3/8 – 3/8″ ID – 6 pieces
FSB31-1/2 – 1/2″ ID – 6 pieces
FSB31-3/4 – 3/4″ ID – 4 pieces
50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
