The L-C Power Filter 2A is a compact LC-type filter designed to clean noisy DC power from 2S to 4S LiPo batteries, specifically for FPV video transmitters and sensitive onboard electronics, eliminating video interference lines and ensuring stable voltage delivery.

Features

  • LC Filter Design: Utilizes a large-value inductor and capacitor to suppress high-frequency noise and voltage ripple from ESC/BEC sources.
  • 2A Continuous Current Rating: Supports power-hungry VTXs and accessories with a robust 2-amp capacity.
  • 2-4S LiPo Input Range: Compatible with standard 7.4V to 16.8V drone power systems.
  • Built-in Reverse Polarity Protection: Safeguards connected equipment from accidental incorrect wiring.
  • Ultra-Compact Form Factor: Measures just 14mm x 5mm and weighs ~1g for minimal impact on build weight and space.

Description

This micro LC power filter is engineered to solve a common issue in FPV builds: video interference caused by electrical noise on the power rail. When ESCs, motors, and other digital components operate, they introduce high-frequency ripple and voltage spikes into the system. This filter’s LC network (inductor-capacitor) acts as a low-pass filter, attenuating this noise before it reaches sensitive components like your video transmitter, resulting in a clean, line-free video feed.

With a maximum input voltage of 20V and a continuous current handling of 2A, it is perfectly suited for modern digital HD VTXs (like CaddxFPV Vista, Walksnail, DJI O3) and high-power analog VTXs. Its extremely low voltage drop ensures your equipment receives nearly the full pack voltage, and the integrated reverse polarity protection adds a critical layer of safety during installation.

Key Features

  • High-Efficiency LC Noise Filtering: Effectively removes ESC and motor-induced electrical noise for crystal-clear FPV video.
  • Robust 2A Current Handling: Capable of powering most FPV video transmitters and auxiliary equipment without overheating.
  • Wide 2-4S LiPo Battery Compatibility: Directly connects to standard drone power distribution systems.
  • Integrated Safety Circuitry: Reverse polarity protection prevents damage from wiring mistakes.
  • Minimal Voltage Drop: Designed for high-efficiency power delivery with negligible loss.
  • Ultra-Lightweight & Compact Design: At approximately 1 gram and 14x5mm, it integrates seamlessly into tight builds, including micro and whoop drones.
  • Pre-Soldered Connecting Wires: Includes wires for quick and easy installation into your power harness.

Applications

  • Cleaning power for digital HD FPV systems (DJI O3 Air Unit, CaddxFPV Vista, Walksnail Avatar) on 5-inch racing or freestyle drones.
  • Eliminating video noise in analog FPV builds, especially on quads with high-current ESCs and powerful motors.
  • Providing clean power to sensitive micro electronics like FPV cameras and receivers in TinyWhoop and micro drone builds.
  • Use in long-range or cinematic builds where a stable voltage supply to the VTX is critical for reliable video link integrity.

Frequently Asked Questions

What is the purpose of this LC power filter on an FPV drone?

This filter cleans 'dirty' power from your LiPo battery or BEC by suppressing high-frequency electrical noise generated by ESCs and motors. This noise often appears as rolling lines or static in your FPV video feed. Placing the filter between your power source and video transmitter (VTX) ensures a clean, stable voltage, resulting in a clear, interference-free video signal.

Can this 2A filter handle a DJI O3 Air Unit or Walksnail VTX?

Yes, the 2A continuous current rating is sufficient for most digital HD video transmitters, including the DJI O3 Air Unit and Walksnail Avatar systems, which typically draw under 2A during operation. It is compatible with their required 2-4S LiPo voltage range (7.4V to 16.8V). Always ensure your total connected load does not exceed the 2A rating.

How do I wire this LC filter into my drone's power system?

Connect the INPUT side of the filter (marked or indicated by the included wires) directly to your main LiPo power leads or a regulated BEC output (2-4S). Connect the OUTPUT side to the power input pins of your FPV video transmitter. The built-in reverse polarity protection helps prevent damage, but always double-check your solder connections against the VTX manual for correct voltage and polarity.
