The FDFILT-28 is a LC Circuit consisting of an inductor and a capacitor. The circuit functions as low-pass filter blocking any frequencies higher than DC from reaching the equipment that is connected at the filter’s output.
The FDFILT-28 can be connected right at the monitor’s power input insuring a clean DC power is entering, thus reducing visual noise that is typically generated on the screen due to “dirty” power source.
The FDFILT-28 also includes a 3 Amp ATC fuse and a protection diode to prevent the connected equipment from damage by short circuit or over-current.
