A capacitor acts like a small energy buffer. It stores a little electricity and releases it when needed. When the controller or LED strip suddenly turns on or changes brightness, it can briefly pull a lot of current. The capacitor helps by smoothing out these quick changes, keeping the voltage steady. This protects the controller and LEDs from sudden voltage drops or spikes and helps everything run more reliably. In simple terms, the capacitor helps keep the power smooth and protects the electronics.
