Variable inductor coils 101μh - 225μh shielded - 5 lot
I'm listing here a lot of 5 unused Shielded Variable Coils, having a code #301.
The price is for a pack of 5 Coils (5 pcs).
It's easy to take off a coil winding for re-winding it up again according to your needs.
Dimensions (the picture has been taken from the coil #101):
Photo showing the coil with both shielding and winding removed (this #301 plastic mould is only one which has a different shape comparing the coils #101, #103, #116, #207 and #207A):
L43 ... 107 turns (an inductance can be adjusted by the screw ferrite core in the range of 101 H till 225 H)
(L45 ... 102 turns and L53 ... 5 turns)
Both the windings L43 and L21 have been wound by the copper wire with a diameter of 0.1 mm.
How to determine number of the winding turns if you know the wanted inductance:
