Backlight Inductors – DO1607B Series
The low profile DO1607B Series has the high breakdown
voltage ratings required for backlight applications. Only
2,49 mm high, they have a footprint of 6,6 × 4,5 mm.
These inductors are constructed of high temperature materials that provide excellent heat deflection to prevent
damage during solder reflow. Standard inductance values
range from 1 to 6.8 mH and custom values are available
to meet specific requirements.
Coilcraft Designer’s Kit C335 contains samples of each
of the standard parts shown. To order, contact Coilcraft

1. When ordering, please specify termination and packaging codes:
Termination:L = RoHS compliant electroplated gold (<50 µin) over nickel
over moly-manganese.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging:C=7″ machine-ready reel. EIA-481 embossed plastic tape
(750 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D
=13″ machine-ready reel. EIA-481 embossed plastic tape
(2500 parts per full reel).
