Best Practices | Adafruit NeoPixel Überguide
Before connecting NeoPixels to any large power source (DC "wall wart" or even a large battery), add a capacitor (500–1000 µF at 6.3V or higher) across the + and – terminals as shown above. The capacitor buffers sudden changes in the current drawn by the strip.

Capacitor with LED Strip
A capacitor in that position is just a local mini power store that is there to compensate for any sudden drawing of power elsewhere in the circuit (for example, when all the LEDs in an LED Strip turn on at the same time) during the time it takes for the power source to make up for it as there is a small delay between a sudden spike in power being drawn and extra power eventually arrive …

Edge Corrections for Strip and Disc Capacitors
We present a precise numerical method for calculating the edge correction for a long rectangular plate capacitor, and compare the results with available approximate formulas. We give numerical results for the disc capacitor which are much more accurate than the approximate formulas at low capacitances (a/h <100, where a = radius and h = separation). These results match or …
