That would be close enough for your needs.Sorry, I read that backwards. I thought it was supposed to be 0.3 Ohms and you got 0.2 Ohms, not the other way around.
Not possible to add negative resistance in this case :doh:
Leonard is right, you may want to measure it to make sure. It might be closer to what you need anyway, despite what the label says.
The gauge that is specified is usually just to help get the resistance correct. If you are getting too much resistance, the only other alternative is to go up a gauge to lower the resistance. It would be more important to get the Ohm rating correct than to use the "indicated" gauge.
Found this at Parts Express:
0.3mH and 0.26Ohms. A little closer. It's 18 gauge.
They also sell 14 and 15 gauge inductors, but you may have to unwind a little to get the impedance right (and they'd be under the recommended resistance).
