It really depends on, what current, power, what size, what accuracy?
yes it is quite possible. if you have a LC meter just buy a ferrite or iron toroid or rod and wrap the wire that can conduct your current around it and at each turn measure inductance until you get 200u. you can also wrap it around a temporary rod and make a air coil but it will be much bigger. if you don't have LC meter search google there are sites that give an approximate equivalent inductance for air coils with a known wire.
regards,
looks like you will need to wind the inductor yourself. google "magnetics" or look up magnetics datasheet. They usually have ratings such as AL [nH/Turn] which can easily help design and get your inductor working.
Of course, it isn't that easy. There are special issues like core loss / copper loss to contend with depending on application of the inductor, but then again you can't master this stuff in a day...
I heard a "Rule of Thumb" estimate for Inductors. A quarter of an inch of wire
is ~5nH. So ~10000 inches of wire should do it. Not too practical.
Also you need to make sure the type of inductor you make is good for
the frequency you intend to use it at.
