RFI-WW-10

Wall Wart RFI Noise Filter Bulk Pack of 10 Filters RFI-WW-10

A simple ferrite ring filter installed on the DC power cable of a wall wart power supply can help suppress the noise interference to nearby electronic devices by suppressing the fundamental switching frequency (usually under 1 MHz) and thereby suppressing harmonics at higher frequencies. This kit includes 10 filters useful for all types of devices powered by wall wart power supplies including laptop computer, routers, cable modems, wireless phone charges, USB chargers, etc.

Mobile RFI kits work two ways: They suppress RFI from on board computers and other sensing/control devices in your vehicle that may cause your radio to be a VICTIM of RFI, and second they suppress RFI generated by your radio as a SOURCE which may affect your on board computers or other devices.  Mobile operations of HF radios (1-30 Mhz) tend to experience more RFI effects than VHF/UHF mobile stations.  If you have both HF and VHF installations in your vehicles, you may need both kits.

To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations.  Each kit uses the appropriate ferrite mix for the frequency range desired.
