Notes: (1) Inductance measured at 100 kHz, 0.1 Vrms, without DC current.
(2) Rated DC current at which inductance will be decreased by 10% from its initial value or the DC current
at which ∆T = 40°C, whichever is smaller.
(3) Resistance measured with both windings conducted in parallel (case size 40 only).
(4) Rated current will be decreased by 50% when parts are connected as coupled inductors.
(5) Part numbers which appear in bold print are standard items and generally available from factory stock.
