Not sure of your interference RFi frequency? Then try using each of the mixes on your RFI problem to determine which one works the best. This Ferrite Ring Mini-Combo Pack is a convenient solution for troubleshooting RFI/EMI from unknown frequencies or multiple frequencies that require multiple suppression mixes. Included in this combo pack are three 2.4″ OD/1.4″ ID ring toroids as follows:

Mix 31 effective from 1-300 MHz for general purpose – quantity: 1

Mix 61 effective from 200-2000 MHz for cell phone, WIFI, HDTV, Cable TV interference – quantity: 1

Individually wrapped and labeled with effective RFI frequency range for easy identification

The ring toroids are useful for AC/DC common mode choking with multiple turns as shown below

AC Cable on F-240 Toroid - 7 turns

AC Cable on F-240 Toroid – 7 turns

DC Cable on F240 - 4 turns

DC Cable on F240 – 4 turns

The ring toroids can also be used on coax or signal lines as shown below:

For RFI/EMI wrap as many turns as possible (usually 6-12) for higher choking (under 30 MHz). For over 25-100 MHz, 1-3 turns om Mix 61 is usually sufficient. Chokes can also be cascaded in series to offer a broader frequency range.
