Application Examples
Measuring Inductor Turns Count
To obtain an app roximate turns count of an
inductor, do the following:
1. Connect the inductor to a current limited
source, as shown.
2. Measure the input current on on e of the
inductor leads.
3. Clamp the current probe around the
inductor and note the current value.
The number of turns is equal to the ratio of coil
current to input current.
The accuracy of this method is limited b y the
current measurement accuracy.
