Notes:
(1) Inductance is measured at 100 kHz, 0.1Vrms without DC current.
(2) DCR Typ. is only for 755 series while 128 series is of DCR Max.
(3) I sat is the saturation current at which inductance rolls off approximately 30% from its initial (zero DC) value.
(4) I rms is the approximate current at which Δ T = 40°C.
