Why is the attenuation in the data shown in ohms and not in decibels, as the term ohm refers to resistance? Why is not the quoted figure in Henrys or millihenrys for a given number of turns?

Asked by: Awkward
Unfortunately we cannot advise why a manufacturer has made a data sheet in the way they have, other than advise this is how it was tested by them.
