Description
Coil bobbin former. 65 mm outer flange, 30 mm inner core diameter and 40 mm length. Suitable for air wound coils in hi-fi audio sytems. For vertical mounting, one end of the flanges cut, providing a straight edge to stand on the surface. With 1.45 mm ~ 15 AWG enamelled copper wire it could produce inductances ~800 mH. Check online air-wound multi-layer calculators for exact inductance estimate.
