LC power filter - LPF-01

LPF-01 LC Power Filter This is a compact and effective LC filter designed to clean a "dirty" DC power supply for sensitive FPV- and RC-components. The filter has excellent properties to reduce the effect of interference radiated through the air and noise conducted via the power wires. Suitable for setups up to 16V and maximum 1.5A load. The 3-pin input allows for a single bypass-signal (If rewired from included cables).

It is now possible to select between common mode and single mode filtering. A solder jumper pad on the input side disables filtering on the negative/ground-lead. If you experience issue with OSD systems, try changing the filter to single mode. Jumper located behind red wire in picture below.
 

This is a compact and effective LC filter designed to clean a noisy DC power supply. Perfect for sensitive FPV- and RC-components in a single battery setup. The filter has properties to reduce the effects of interference radiated through the air and noise conducted via the power wires. One advantage of this filter is that both the negative and positive leads are filtered (common mode).

Problems often occur on sensitive FPV video systems when long power leads (15cm+) are used, limited space for wiring, improperly filtered transmitters, noise from speed controller or switch mode DC-DC voltage converter, or most commonly a shared battery is used to minimize weight. The interference can result in video lines, banding, random drop-outs, and reduced transmission range. A low-pass LC-filter will help attenuation most of the high frequency power supply noise and interference.

A common-mode choke coil is used to provide large impedance (resistance) against common-mode current noise picked up by both power leads. It is more effective for noise suppression than conventional ferrite ring and differential-mode inductor setups. This means that noise coming in on both wires will canceled each other out leaving only the regular differential-mode current flowing through the choke.

The large series inductor will give good current noise suppression between the input and output. Low resistance of the coils cause only minimum voltage drop over the filter (<200mV) and the low-ESR capacitor used will ensure efficient ripple voltage (noise) reduction (<120mVpk-pk).

 

Combine it with the RMRC Battery Tap (pictured below, sold separately) and you can easily power your video system directly off of your main flight battery!
Only known brand and quality parts are used to offer the great filtering properties.  Every filter is tested before being shipped from the European manufacturer.
