Notes: (1) Inductance is measured at 1kHz without DC current.

(2) The rated DC current is based on an approximate 20°C temperature rise.

(3) The incremental current (INCR I) is the approximate current at which the inductance will be decreased by 5% from its initial (zero DC) value

due to saturation.
