# Best Capacitors for FPV Drone Builds (2026) Source: https://dronefpvlab.com/best/capacitors Updated: 2026-09-14 Publisher: Drone FPV Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://dronefpvlab.com/how-we-research#our-score A capacitor on the power input smooths voltage spikes and filters noise, protecting your electronics and cleaning up your video feed. The specs that matter are voltage rating with headroom above your pack, capacitance, and low ESR for effective filtering. Adding one across the main battery leads helps absorb the current spikes that aggressive flying and long motor wires generate, which can otherwise stress your ESC and introduce lines in the image. This guide fits builders chasing clean video and reliable power, especially on higher-voltage or longer-lead setups. Choose a voltage rating well above your battery's peak, and mount the cap where its leads stay short and protected. Good soldering and a bit of shielding keep it secure through crashes. Pick a low-ESR capacitor rated safely above your voltage, install it across the battery input, and you get steadier power and a cleaner picture. ## Picks ### 1.
