Capacitors and Servomotors

Hello, I have read that it is necessary to use capacitors together with my servo motors to stabilize the current, but I don’t know what their capacity should be, is there any way to calculate it? My sevomotors have a nominal voltage of 4.8V and use 50mA.

    4.7uf works well. Get a 16 Volt cap, You always want to double the working voltage.

    Rafav: I build many servo devices without any caps. More important IMO is to use adequately large wiring and a capable battery (LiPos rule). I always use two decoupling caps (.01 uF and 10uF) right at the microcontroller pins though, for clean power.
