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.
