Where can I see the inductance value for the frequency at which I would like to use the inductor?

Please explain the specifying condition for the inductance value of a multilayer inductor for high frequency circuits.

Please explain the specifying condition for the rated current of a multilayer inductor for high frequency circuits.

Do multilayer inductors for high frequency circuits experience a decrease in inductance due to DC current (DC bias characteristics)?

Please explain the specifying conditions for the rated current of inductors for power circuits (Power Inductors).

What is the DC bias characteristic of an inductor for power circuits?

In there aging?
