Panasonic FR 470µF 35V Low-Impedance FPV Capacitors – Pack of 5

Premium genuine Panasonic FR-A 470µF 35V low-impedance aluminium electrolytic capacitors, supplied as a pack of five. Selected by Pure Drone following FPV product testing and evaluation as our preferred compact power-filtering capacitor for reliable 4S and 6S builds.

Why FPV drones use a capacitor

Soldered across the ESC battery input, the capacitor absorbs short voltage spikes and smooths high-frequency electrical noise produced by the ESC and motors. This can help protect connected electronics, reduce interference in the video feed and provide cleaner power to the flight controller, VTX and camera.

Key benefits

• Low impedance and high ripple-current capability
• Helps suppress voltage spikes at the ESC battery input
• Can reduce electrical noise, video interference and power-related instability
• Compact 10 × 16mm radial package
• High-reliability Panasonic FR-A series
• Suitable for correctly installed 4S and 6S FPV builds

Installation

This is a polarised component. The stripe on the body marks the negative terminal. Solder positive to battery positive and negative to battery negative, as close as practical to the ESC battery pads, with the leads kept short and insulated. Reversing polarity can cause the capacitor to fail or vent.

A fully charged 6S LiPo is 25.2V, leaving nominal headroom below the capacitor's 35V rating. For unusually long battery leads or exceptionally severe transient conditions, a higher-voltage capacitor may be preferable.
