Specifications

What Is an LC Filter Module?

An LC filter (inductor-capacitor filter) is a passive electronic circuit that smooths out voltage fluctuations and suppresses electromagnetic interference (EMI) on your power rail. In FPV drone builds, this is especially important for eliminating "video noise" or static caused by motor and ESC interference, resulting in a much cleaner on-screen display (OSD) and AV transmitter feed.

Perfect For

• RC FPV freestyle drone builds
• AV transmitter power filtering
• Drone camera power lines
• Any RC electronics system requiring clean, stable power

Frequently Asked Questions

Q: What does the IFlight LC Filter Module 3A 50V do in an FPV drone build?

A: The IFlight LC Filter Module filters electrical noise and voltage spikes from your drone's power rail using an inductor-capacitor (LC) circuit. This results in a cleaner power supply to your video transmitter and camera, reducing static or interference in your FPV feed. The 3A/50V rating makes it compatible with most FPV freestyle drone setups.

Q: What is reverse polarity protection and why does it matter?

A: Reverse polarity protection prevents damage to your electronics if the power connections are accidentally wired backwards (positive to negative or vice versa). The built-in protection circuit in this LC filter module cuts off current flow in a reverse-polarity scenario, safeguarding your AV transmitter, flight controller, or camera from potentially costly damage.

Q: Is this LC filter module compatible with my AV transmitter and FPV camera?

A: Yes — this module is designed for use with RC FPV freestyle drones, AV transmitters, and drone cameras. With a 50V maximum voltage and 3A current rating, it is compatible with the vast majority of FPV builds. Its compact 2 × 0.7 cm PCB form factor makes it easy to integrate into tight spaces in your drone frame.
