Notes:
(1) Test conditions for case sizes 10, 20, 45 & 46 = 100kHz, 0.1 Vrms without DC current. Inductance for case sizes 30, 40, 50 & 60 is measured
at 1kHz 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 ΔT = 40°C, whichever is lower.
