0.1uF 50V 104 DIP Ceramic Disc Capacitor
pF = picoFarad, 10-12 farad (that’s one trillionth!) 1 uF = 1 000 000 pF
uF = microFarad (the letter u substitutes for the Greek letter micron) 1 F = 1 000 000 uF
mF = microFarad (not milliFarad as you’d expect) 1 F = 1 000 000 000 000 pF
The one- and two-capacitor filters can be used in combination making a three-capacitor filter. As shown in figure , one capacitor (again 0.1µF) is connected across the motor terminals, and one capacitor (0.047µF) is connected to each of motor terminals and the motor casing.
This configuration is the most effective, and will all but guarantee that motor noise will not be the source any odd circuit behavior you may run into.
Note there is absolutly no ‘guarantee’ that this configuration will eliminate electrical motor noise.
