If it says mfd it should mean mili-farads - not micro-farads.
Nobody uses millifarads, except maybe the boom car crowd. "mfd" or more
commonly "mf", prior to (the 1960's) metrification/SI rationalization
meant Microfarads. And picofarads were "mmf" micro micro farads.

That's not what I see in most articles or catalogs.
1 F is 1 farad
1 mF is .001 or 1x10^ -3 or 1 milli-farad
1 uF is .000,001 or 1 x 10^ -6 or 1 micro-farad
1 nF is .000,000,001 or 1 x 10^ -9 or 1 nano-farad
1 pF is .000,000,000,001 or 1 x 10^ -12 or 1 pico-farad
Many capacitors are in mF in industrial power supplies. Got to get the
current step response down to 20 Hz in some cases.
