FlyFishRC UNICON UPL Capacitor

Capacitors act as a buffer for your drone's power system. They absorb voltage spikes caused by your motors and help filter out electrical noise, which prevents video interference and protects your sensitive flight controller and ESCs from damage.

A 35V rating is generally perfect for 4S and 6S LiPo battery setups. As long as your battery voltage does not exceed the capacitor's rating, it will function safely and effectively.

For the best results, solder the capacitor directly to the positive and negative pads where your battery lead connects to your ESC or power distribution board. Keeping the leads as short as possible maximizes their filtering efficiency.

Yes, these are electrolytic capacitors and are polarized. You must ensure the negative lead (usually marked with a stripe on the side of the capacitor) is soldered to the negative pad and the positive lead to the positive pad to avoid damaging the component.

With dimensions of 10mm x 12mm, they are relatively compact, but space can be tight on smaller frames. Check your build's clearance before mounting to ensure they won't interfere with propellers or other components.
