1.Perfect for sensitive FPV and RC components in a single battery setup. 2.Both the negative and positive leads are filtered (common mode);The classically designed LC filter is suitable for use with image transmission, effectively reducing noise, interference and ripple caused by DC power supply. 3.Reduces DC-DC switcher supply ripple and helps clean loud from a shared battery. 4.Reduce the effects of interference radiated by the air and noise carried over the power wires.Help dampen most of the high frequency power supply noise and interference. 5.Always suppress the noise in the power to your FPV setup (e.g. your VTX and FPV camera).
