Product Details
MPN: RFI-SMPS
Type: NEW
Country/Region of Manufacture: United States
Filter Power Rating (PEP watts): n/a
RFI Suppression Range (MHz): 150 KHz - 10 MHz
Typical Use:: SMPS common mode noise suppression

The RFI-SMPS is a common mode noise reduction filter set which filters both the AC input and DC output of common SMPS power supplies. These filters effectively isolate the AC power cord and DC output cable from acting as antennas for the internal switching power supply generated noise. The mix 75 filters suppress RFI fundamental frequencies (and the harmonics also) from 150 KHz to 10 MHz. Simple to install on cables without any device modification.

Used for amateur and commercial radio transceiver power supplies, cable TV boxes, laptop computers, or any electronic device powered by an external switching power supply.

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
