    DC Motors Disc Capacitor How To Select Size ?(+Connection)
    - For circuit protection...
    + Is there any other protection you can use ?

    I have:
    Speed+Direction Changing Unit:
    2x18650
    Batteries=7,4V
    PWM+Potentiometer (LINK TO SITE)
    2x On-Off-On switches
    Mini Digital Voltmeter

    Motors DC: 2 Pieces: 6V; 0.04A

    Do I Need Something Else To Protect the Components ???
    (Suggestions So I Won't Brake Anything When Building) :D
    Thanks

    Ehen using small hobby motors anything from about .01 to .1uF(10-100nF) directly across the pos. and neg. motor wires is standard. Rate them at 16 v0lts or more. The most commonly used are .1uF @ 50V disk capacitors. You can use 2 caps, one from each terminal to the case for even better filtering of RF.
