HM66A - 0420 1R2 N LF 13

Model Series

Case Size :

Inductance Code:

First 2 digits are significant. Last digit

denotes the number of trailing zeros. For

values below 10μH, “R” denotes

the decimal point.

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.
