IFlight LC Filter Module 3A 50V – Reverse Polarity Protection FPV

The IFlight LC Filter Module 3A 50V is a compact, high-performance power filter designed for RC FPV freestyle drones, AV transmitters, and onboard cameras. Its built-in reverse polarity protection safeguards your electronics from accidental incorrect wiring, giving you peace of mind during every build and flight session.

Constructed on a quality PCB and measuring just 2 × 0.7 cm (0.78 × 0.27 in), this ultra-lightweight module slots neatly into tight drone frames without adding unnecessary bulk. The LC (inductor-capacitor) filter circuit effectively suppresses electrical noise on the power line, delivering cleaner, more stable voltage to your video transmitter and camera for noticeably cleaner FPV footage.

What Is an LC Filter and Why Does It Matter?

In FPV drone builds, motor noise and ESC switching can introduce voltage ripple that appears as static lines or interference in your FPV video feed. An LC power filter uses an inductor and capacitor in tandem to block high-frequency noise before it reaches your camera or video transmitter — resulting in a noticeably cleaner picture.

Who Is This For?

This module is ideal for FPV freestyle pilots, drone racers, and hobbyist builders who want to protect their electronics and improve video quality without adding weight or complexity to their builds. It also makes a great value addition to any FPV spare parts kit.

Frequently Asked Questions

Q: What does the IFlight LC Filter Module 3A 50V do for my FPV drone?

A: The IFlight LC Filter Module filters out electrical noise and voltage ripple on your drone's power line — most notably from motors and ESCs — before it reaches your FPV camera or AV video transmitter. This results in a cleaner, interference-free video feed. The built-in reverse polarity protection also prevents component damage if power is accidentally connected the wrong way.

Q: What voltage and current ratings does this LC filter module support?

A: This module is rated for up to 3A continuous current and up to 50V, making it compatible with most common FPV drone battery configurations including 2S through 6S LiPo setups used in freestyle and racing builds.

Q: How small is this filter module and will it fit in my drone frame?

A: The IFlight LC Filter Module measures just 2 × 0.7 cm (approximately 0.78 × 0.27 inches), making it one of the most compact power filter solutions available. It is designed to fit inside even the tightest micro and mini FPV drone frames with ease.

Q: Is the IFlight LC Filter Module compatible with my FPV camera and video transmitter?

A: Yes — this LC filter module is broadly compatible with most FPV cameras and AV video transmitters used in RC freestyle drones, racing drones, and general FPV builds. Simply wire it in-line between your power source and your camera or VTX power input.
