Notes: (1) Inductance measured at 100 kHz, 100 mVrms, OADC.
(2) RMS current is the approximate current at which inductance will decrease by 10%.
from its initial value (zero DC) or the DC current at which
∆T
= 40°C, whichever is lower.
(3) Saturation current for approximately 30% roll-off.
(4) DC resistance measured at 20°C.
