Description

This LC power filter utilizes a low-pass circuit with large-value inductor and capacitor components to suppress high-frequency noise commonly generated by ESCs, switch-mode BECs, and long power leads in single-battery FPV setups. By filtering both supply rails, it effectively mitigates video banding, lines, and dropouts that degrade FPV feed quality.

Its robust construction is engineered for the demanding electrical environment of multirotors and RC aircraft, providing a clean power source for video transmitters, cameras, and sensitive flight controllers. The filter’s compact footprint allows for installation in space-constrained builds without adding significant weight.

Key Features

  • LC low-pass filter topology for effective high-frequency noise attenuation.
  • Common-mode filtering on both power rails reduces conducted interference.
  • Integrated reverse polarity protection diode prevents damage from incorrect wiring.
  • High-current inductor and low-ESR capacitor selected for optimal performance in FPV applications.
  • Durable PCB with through-hole components for reliable operation in high-vibration environments.
  • Designed to mitigate noise from shared battery setups powering both motors and video systems.

Applications

  • Cleaning power for analog or digital HD FPV video transmitters (VTX) and cameras in noisy 5-inch racing or freestyle quadcopters.
  • Providing stable voltage to sensitive flight controllers and GPS modules in long-range or autonomous UAVs using a shared battery.
  • Reducing motor-induced noise in Cinewhoop and micro FPV builds where space for separate power filtering is limited.
  • Improving video feed quality in RC planes or helicopters where the motor ESC shares a battery with the FPV system.
  • Ensuring clean power for ImmersionRC or similar brand receivers in complex FPV rigs.

Frequently Asked Questions

What is the maximum voltage and current this LC filter can handle?

The RTF LC Power Filter is rated for a maximum input voltage of 16V, making it suitable for 2S to 4S LiPo batteries (up to 16.8V fully charged). It has a continuous current rating of 2A. Exceeding these ratings may damage the filter and connected components.

How do I wire this filter into my FPV drone or RC model?

Connect the filter's INPUT side to your main battery or power distribution board (PDB). Connect the OUTPUT side to your sensitive devices like the video transmitter, camera, or flight controller. Ensure correct polarity, as the built-in reverse protection will safeguard against accidental reverse connection, but it is not a substitute for proper wiring.

Will this filter help with video lines caused by my drone's motors?

Yes. Motor Electronic Speed Controllers (ESCs) generate significant electrical noise on the power lines. This LC filter is specifically designed to attenuate that high-frequency noise, which often manifests as horizontal lines, banding, or static in the FPV video feed when the throttle is applied.

Can I use this filter on a 6S drone or with devices drawing more than 2A?

No. The filter is rated only for up to 16V (4S). A 6S pack (25.2V) would exceed its voltage rating and likely cause failure. Similarly, connecting a load that draws more than its 2A continuous current rating, such as a high-power VTX, could overheat and damage the inductor.
