Specifications (Cont’d)
Notes:
(1) Inductance is measured at 100 kHz, 1.0 Vrms, 0 ADC.
(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.
