Description

This micro LC filter is engineered to suppress electrical noise generated by brushless motor ESCs, which manifests as rolling lines or static in the FPV video feed. By employing a high-quality inductor and capacitor network, it smooths voltage fluctuations from a shared LiPo battery, delivering a clean power rail to sensitive FPV components.

Its vanishingly small size and lightweight construction (approximately 1g) make it an ideal solution for weight-critical micro and nano drone builds where space is at a premium. The filter is rated for a maximum continuous current of 3A, sufficient for most analog and digital HD VTX systems, and features built-in reverse polarity protection to prevent damage during wiring.

Key Features

  • High-efficiency LC filtering circuit eliminates motor and ESC noise from the power line.
  • Robust 3A current handling supports power-hungry digital HD VTX units and camera setups.
  • Ultra-lightweight design at approximately 1 gram minimizes impact on drone flight performance.
  • Integrated reverse polarity protection safeguards connected FPV equipment from wiring errors.
  • Very low voltage drop ensures the FPV system receives near-source voltage levels.
  • Wide input voltage range compatible with 1S (3.7V) up to 6S (25.2V) LiPo battery configurations.

Applications

  • Noise suppression for analog VTX and camera combos on 3-inch to 7-inch FPV drones.
  • Clean power delivery for digital HD systems (DJI, Walksnail, HDZero) on freestyle and racing builds.
  • Essential filtering for micro and whoop drones using a single-battery power setup.
  • Improving video feed clarity in long-range FPV platforms where electrical noise is pronounced.
  • Power conditioning for auxiliary payloads like LED lights or telemetry modules.

Frequently Asked Questions

What is the primary function of this LC power filter?

The filter's primary function is to remove high-frequency electrical noise generated by brushless motors and ESCs from the power line supplying your FPV video transmitter and camera. This noise manifests as rolling lines, static, or waves in the video feed, especially during throttle changes. The LC circuit (inductor and capacitor) smooths these voltage fluctuations, providing a clean and stable voltage rail.

Can this filter handle the power requirements of a digital HD FPV system like DJI or Walksnail?

Yes, with its 3A continuous current rating, this filter is capable of supplying sufficient clean power for most digital HD FPV air units and cameras, which typically draw between 1A to 3A under peak load. Its wide 1S to 6S input voltage range also covers the standard battery configurations used with these systems. Ensure your wiring can handle the current and that the filter is installed between the main battery lead and the air unit's power input.

How do I install this LC filter on my FPV drone?

Installation is straightforward. Solder the filter's input wires (typically marked or colored) to your drone's main power distribution board or battery lead, observing correct polarity. Then, solder the filter's output wires to the power input pads of your FPV video transmitter. The built-in reverse polarity protection adds a safety margin, but always double-check connections. Due to its small size, it can be mounted directly on the VTX or secured with double-sided tape.
