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

Keep your FPV build running clean and stable with the IFlight LC Filter Module 3A 50V. This compact PCB-based LC filter is engineered to suppress electrical noise and voltage ripple on your drone's power line, delivering cleaner power to your video transmitter, camera, and other sensitive electronics. Built-in reverse polarity protection adds an extra layer of security, guarding your components against accidental incorrect wiring connections.

Whether you're racing on a tight track or flying freestyle lines, this low-profile filter module fits neatly into even the most space-constrained FPV builds — measuring just 2 × 0.7 cm (0.78 × 0.27 in). Rated at 3A continuous current and up to 50V, it handles the demands of modern RC power systems with ease.

Frequently Asked Questions

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

A: The LC filter module smooths out voltage ripple and reduces electrical interference on your power line. When installed between your battery/PDB and sensitive components like an FPV camera or video transmitter, it delivers cleaner, more stable power — which translates to a clearer video feed and more reliable electronics performance in your FPV drone.

Q: What does the built-in reverse polarity protection do?

A: Reverse polarity protection prevents damage to your drone's components if the power leads are accidentally connected in reverse (positive and negative swapped). This built-in safeguard can save costly electronics from being burned out during installation or maintenance of your RC build.

Q: Is this LC filter module compatible with my FPV drone setup?

A: With a 50V maximum voltage rating and 3A continuous current rating, this module is compatible with most 2S–6S LiPo-powered FPV freestyle and racing drone builds. Its ultra-compact 2 × 0.7 cm size makes it easy to fit into almost any frame. Recommended for builders aged 14 and older.

Q: What is included in the package?

A: Each order includes 1 × IFlight LC Filter Module (green PCB). No batteries or additional hardware are included.
