Inductor

laxmid said:

1.L1 is a custom inductor wound with about 80 turns of 0.5mm magnet wire around a toroidal core with a 40mm outside diameter.
1.L1 is made by winding 60 turns of 0.63MM magnet wire on a toroidial core measuring 15MM (OD) by 8MM (ID) by 6MM (H).

What is the meaning i mean what is the inductance .

please help.

Thanks.

There are two ways to tackle it. The best is, if you know the manufacturer say like Amidon, then they give you a formula to calculate the value using the AL value of the core material which is easily converted to microhenrys.

You can also make an oscillator and by measuring the resonant frequency of the oscillator and having a known value of capacitance you calculate the inductance by converting from the formula for resonant frequency.
