COIL INDUCTANCE AIR CORED 20mH
This coil is the same design and format as the coils used on the IEC small Demonstration Transformer and also inside the "Hodson" Induction Kit.
2 x 4mm banana sockets are formed as part of the coil body.
The number of turns has been adjusted to provide an inductance of 20 millihenry.
Others in the series are 5, 10 and 15 millihenry.
