Hello,
Hopefully a quick question. When I read the datasheet for (at least one manufacturer) the indicated inductance is actually half the measured inductance across one winding. For example, PLA10AN7720R7D2 is marked as 7.7mH, When I physically measure the inductance of a single winding it's showing as just over 14mH.
The same with PLA10AN3630R3D2, marked as 36.0mH, measuring it shows around 68mH.
Is this the convention for common-mode chokes? I only have the above two types, so I cannot measure others that I read the datasheets for.
I just wanted to check if they all show half of the value of individual winding, it just doesn't make any sense to me.
PLA10AN3630R3D2B
Thanks,
