Specifications of the HT1 MOA3 S30
Rev. 1.1
1997-08-19
For a rough estimation ( ± 10 %) of the number of coil windings following formula can be used.
It is assumed that the winding is done in circular form.
N=
1,8 5
L
u
2 U ln ( )
d
N ... Number of windings
L ... Inductance [nH]
U ... average coil circumference [cm]
d ... copper diameter [mm]
u ... average coil circumference [mm]
For fine tuning a measurement of the inductance and an according adjustment of the number of
windings is necessary. This process always needs some iterations.
