Why Capacitors Are Essential in FPV Drone Builds
In the world of FPV drones, a $2 capacitor can mean the difference between a flawless flight and an expensive trip to the repair bench. Learn how voltage spikes, electrical noise, and current surges can destroy your electronics, and why a simple capacitor is your quad's best defense.
What You'll Learn:
- Voltage Spike Protection: How capacitors protect ESCs and flight controllers from motor-induced voltage spikes
- Video Feed Filtering: Eliminate electrical noise for cleaner FPV video transmission
- Low-ESR Importance: Why Equivalent Series Resistance matters for effective filtering
- Proper Placement: Where to mount capacitors for maximum protection
- Component Selection: Choosing the right capacitance and voltage ratings for your setup
Key Takeaway: A 1000µF 35V low-ESR capacitor costs less than a prop set but can prevent hundreds of dollars in component damage.
