Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.
RFI/EMI Solutions from KHz to GHz
Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.
The simplest, most cost effective DC power cord noise filter is a ferrite ring installed as shown in the picture (at the radio/device DC input) to stop DC feedback radiation back into the DC power line or into the radio/appliance to suppress common mode power line noise current on the DC power cord or to suppress common mode noise present on the power lines from degrading the performance of the attached device.
These chokes are cheap, easy solution for RFI issues. Just replace your existing power cord with these prewound cables and enjoy interference free operation.
