SPECIFICATIONS

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.
