Notes : (1) Inductance is measured at 100kHz, 0.1Vrms, 0Adc.
(2) When leads connected in parallel, DCR is half the value. When lead connected in series, DCR is twice the value
(3) Isat current is the saturation current at which inductance rolls off approximately 30% from its initial (zero DC) value.
(4) Irms equals DC current, that causes component to increase by 40°C from 25°C ambient.
(5) Irated current is the rated current at which inductance rolls off approximately 10% from its initial (zero DC) value.

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) Isat is the saturation current at which inductance rolls off approximately 30% from its initial (zero DC) value.
(4) Irms is the approximate current at which ΔT = 40°C.
