Notes:
(1) The rated current is approximate current at which inductance will decreased by 20% from its
initial (Zero DC) value.
(2) DC Resistance is measured at 25°C.
(3) The Heating Current is the DC current, which cause the component temperature to increase by
Approximately 50°C. This current is determined by soldering the component on a typical PCB, and
Then apply the current to the component for 30 minutes.
(4) Isat is the saturation current at which inductance rolls off approximately 30% from its initial
Unbias inductance value.
(5) Box layout, proximity of other component, trace size and airflow will affect temperature rise and
must be considered when selecting an inductor.
