Notes
(1) _{All test data is referenced to 25 °C ambient}
(2) _{Operating temperature range -55 °C to +155 °C}
(3) _{DC current (A) that will cause an approximate ΔT of 40 °C}
(4) _{DC current (A) that will cause L0 to drop approximately 20 %}
(5) _{The part temperature (ambient + temp. rise) should not exceed}
155 °C under worst case operating conditions. Circuit design,
component placement, PWB trace size and thickness, airflow
and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
(6) _{In this configuration, current flowing opposite directions through}
coils cancels and the 8.0 μH inductance is very stable with
varying current. Observe the heat rating current to avoid
excessive temperature rise in this configuration.
