I'm looking for a 390uH inductor for a Boost PFC choke 250W output
power.
After spending some time browsing data sheets,I'm confused why only
the DC current rating is shown. There is never any graph for current
vs inductance or inductance vs frequency or max peak current to avoid
saturation or graphs for core loss.
From looking at a data sheet on a Bourns vertical mount Toroid 560uH
@1kHz They specify at rated DC current an inductance drop from the
original 560uH to 314.18uH.
My PFC choke specifications at 65kHz are 4.9Apk and 3Arms would the
2321 560uH 3.6A one here be a possible candidate?

I could use a coilcraft part I have but its bigger then I would like
to use part C1062-BL

Note the detailed specs compared to 99% of the other inductor
datasheets.
