Copper Winding Wire (magnet wire) 100g Air Coil
These air coils contain a minimum of a 100g or enameled copper winding wire – used for winding various magnetic coils, chokes and transformers.
These Air-core coils are held in shape by cable ties which can be easily removed.
The coil has not been set with any resin compound and the wire will unwind with a minimal effort when required.
Should one wish to use the whole coil as it is – it comes with both ends tinned and ready to solder.
Coil Dimensions (approximate): Outside Diameter – 39mm ; Height – 17mm (19mm with cable ties)
Inside Diameter – 17.7mm (15mm including cable ties)
Available wire diameters in mm with
a corresponding AWG Gauge: Wire Length per 100g: Induction: DC Impedance:
0.5mm/AWG#24 ~ 56metres 7.5mH 4.8 Ohm
0.6mm/AWG#22-23 ~ 39metres 3.7mH 2.3 Ohm
0.7mm /AWG#21 ~ 28meters 2 mH 1.2 Ohm
0.8mm /AWG#20 ~ 24meters 1.2mH 0.8 Ohm
1mm /AWG#18 ~ 14meters 0.43mH 0.3 Ohm
1.2mm /AWG#16-17 ~ 10meters 0.18mH 0.2 Ohm
1.4mm/AWG#15 ~ 7metres 0.09mH 0.1 Ohm
Induction was measured as-is with an air-core.
Induction will off course be much greater with magnetic core inserted.
