Notes: (1) Rated current is the approximate current at which inductance will be decreased by 15% from its initial (zero DC) value or the current at
which
∆T
= 50°C, whichever is lower.
(2) DC Resistance measured at 20°C.
(3) ISAT is the saturation current at which inductance rolls off approximately 30% from its initial value.
(4) Board layout, proximity of other components, trace size and airflow will affect temperature rise and must be considered
when selecting an inductor.
