Hi everybody,
I'm trying to modelize the behaviour of a ferrite with LTspice (see attachment).
The problem is that, basing on the datasheet, its impedance is frequency-dependent (see the maximum curve in the image attached).
So far, I think a good idea is to consider that it has just an inductive behaviour. In particular, I'd like to take into account the variation in its gradient at around 700 kHz (as if the inductance switches from 7 uH to 1.3 uH).
How can I do that in LTspice?
Actually, after testing the ferrite performance with LTspice, I'll have to import its model in Simetrix, so I fear a frequency-varying inductor is not a good solution.
Thank you,
Andrea
