Microfarad is a unit of capacitance used in most electronic applications which is equivalent to one millionth of a farad. Ampere on the other hand measures the rate of electron current or flow inside an electrical conductor.

It is the apostrophe symbol, a single character after the number as shown below. No space is required. Symbol: ' Example: 35' = 35 feet
alt 251 on the keypad
It's a long-obsolete symbol for microfarad. It also appears capitalised, MFD.
' μfd ' is a symbol that's widely used.That first character is the Greek letter 'mu', widely used in place of 'micro'. (Use your imagination, and you may be able to see how 'mu' evolved into the letter 'm'.)Alternative AnswerAlthough 'μfd' is sometimes seen printed on older capacitors, the SI symbol for microfarad is μF.
30 microfarads
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
On the list that you posted with the question, there are no items that designate a 7 microfarad capacitor.
The symbol for a capacitor is two parallel lines with one curved line connecting them. It is often used in circuit diagrams to represent a capacitor.

1K = 1uF
1000000 microfarad
To repair a 680 microfarad capacitor, buy a new one and install it in place of the old one. It is unrealistic to attempt repair of a capacitor.
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
uF is a measurment in electronics called Microfarad. You will typically see uF on Capacitors for example 400Volt 150uf would be a capacitor rated at 400 volts and 150 microfarad.
