Inductor - Air core 40uH
2.5 inch by 4 inch 16 gauge tinned - 40uH. Back in stock! The black insulators have little holes on one end and a little spigot on the other which fits into the little holes - you with me? You can make an extended coil although why you might want 80uH I don't know....However the facility is there... No longer packed in old sellotape cardboard cores - classy new super heavy duty cardboard tubes. This is a reduced price for January 2018 - it will increase to $33 in February.
