Document 363-1 Revised 09/16/03IntroductionWhen comparing published electrical values, engineersrequire a common basis for comparison. Ideally, a 100 nHinductor with a self Resonant Frequency (SRF) of 1 GHzfrom one manufacturer is equivalent to inductors with thesame published values from every other , however, the test instrument and fixture af-fect the SRF measurement. Since all manufacturers donot use the same instruments and fixtures, not all pub-lished SRF specifications are equivalent, which makesinductor comparisons difficult.
