mfd Cap compared to a uf Cap

hi Tony,
welcome to the forum

well... its all a little confusing technically mF(d) stands for milliFarad
and uF is microFarad(an order of magnitude smaller).

The confusion comes where some older capacitor manufacturers used mF instead of uF on their devices. and in that reasoning they mean the same

In today's reality I would doubt that you could actually buy a 1200mF capacitor
rather it would be 1200uF written on it

A value that large, would assume it came out of one of the power supply sections of your TV ?
I suspect you wont have any probs installing the 1200uF cap

Wow! I thought mfd as a marking disappeared shortly after American explorers discovered France!

If the 1200mfd unit was found in the set, then I would also imagine that you may have to replace all your tubes with valves (or vice versa).

You will note that mfd is a combination of a multiplier (m) and a unit (fd). The SI unit for capacitance is the Farad, correctly abbreviated F. If you see it abbreviated as fd, then you can't assume that the multiplier "m" is a SI abbreviation.

 

I can't remember the last time I saw a capacitor marked in mfd.

I do recall them when they were called condensers, or from equipment of some vintage, but I'm staggered anyone manufactures something labelled that way.

Perhaps I've just not noticed? Or perhaps they are capacitors not used in "electronics" (e.g. motor start capacitors or for power factor correction)
