Of course, it mentions the frequency they tested it at, its 100Khz, so It can "handle" at least 100Khz before it starts losing inductance. (Screenshot from first datasheet):
Is it possible to tell its maximum self-resonant frequency (even with an approximation) just by the datasheet's rest data, before ordering it? (I know I can test it myself in the lab after I order it, but I would like to know beforehand).
Screenshots from first datasheet:
I want to use the inductor on a buck converter which runs at 1Mhz, driving a 1.5A load. Might be helpful information.
For some inductors that the datasheet actually tells you the Self resonant frequency, I noticed the more the inductance increases, the more the SRF drops. maybe this can help somehow?:
