Multi-Ring/Multi-Snap On Combo Pack, Mix 61, RFI Range 200 - 2000 MHz - 14 filtersProduct DetailsBrand: Palomar EngineersUPC: Does not applyMPN: MRSCP-61-14Type: NEWCountry/Region of Manufacture: United StatesThis ferrrite Multi-Ring/Multi-Snap-On Combo Pack is a convenient solution for troubleshooting RFI/EMI (200 - 2000 MHz) with various diameter cables ranging from 1/4" to 1.4"/35.6mm for use as either single turn or multiple turn RFI filters using ferrite rings and snap-ons.
The filters are useful for RF coax, AC/DC power cables, and device interconnection cables. This frequency range is used in switching power supplies, variable speed motors, LED light dimmers and many other DC control circuits. Use on inputs and outputs of these devices to reduce or eliminate RFI.
Always use a snap on or ring 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 turn). Included in these combo packs are our most popular snap on sizes as follows:
Combo Pack includes the following:
F240-61 ring – 1.4″/35.6mm ID – 4 pieces
FSB61-1/4 – 1.4"/6.3mm ID – 6 pieces
FSB61-1/2 – 1/2″/12.7mm ID – 4 pieces
Normal Retail price is $106 for these parts - buy more than 1 set and save even more!
Use multiple turns thru the center for best results.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
