Notes: 1. Inductance measured at 1.0kHz without DC current.
2. Rated DC current is the approximate current at which inductance will be decreased by 10% from its initial (zero DC) value
or the DC current at which ∆T = 40°C, whichever is lower.
3. Part numbers which appear in bold print are standard items and generally available from factory stock.
