This cannot be an electrolytic capacitor, since they will just explode from the high switching rates. I found film capacitors to be the best option for this circuit, but ceramic type capacitors may also work well. Most schematics suggest using a 1uF capacitor in this circuit, but I found that I got far better performance from smaller capacitors.
