(2) DC resistance is measured at 20°C. (3) Rated current is the approximate current at which inductance will be decreased by 35% from its initial (zero DC) value or the current at which ∆T = 40°C, whichever is lower. (4) Short pin 1 to pin 4, & pin 2 to pin 3 when HM68-50XXX ( Inductance below 22µH) model is in use.
