Shielded Surface Mount Power Inductors
Make Possible
Model HM66A
Notes: (1) Inductance for case size 0420, 0520, 0530, 1030 & 1050 is measured at 100 kHz, 0.1 Vac without DC current.
(2) Inductance for case size 0628, 0728, 0730, 0732, 0745, 1045, 1255, 1265 & 1275 is measured at 1 kHz, 0.5 Vac without DC current.
(3) The rated current for case size 0312, 0315, 0318, 0420, 0520, 0530 & 0628 is the approximate DC current at which the inductance will be decreased by 30%
from its initial (zero DC) value.
(4) The rated current for case size 0630 is the approximate DC current at which the inductance will be decreased by 35% from its initial (zero DC) value.
(5) The rated current for case size 0728, 0730, 0732, 0745, 1045, 1255, 1265 & 1275 is the approximate DC current at which the inductance will be decreased
by 30% from its initial (zero DC) value.
(6) The rated current for case size 1030 & 1050 is the approximate DC current at which the inductance will be decreased by 25% from its
initial (zero DC) value.
