Backlight Inductors - DS1608BL Series
These tiny shielded inductors are specially engineered
for demanding backlighting applications. They feature
high breakdown voltage and exceptional efficiency: DC
resistance is 10% to 60% lower than other inductors.
These magnetically shielded inductors are designed
with a flat top and constructed of heat resistant materials
to ensure trouble-free assembly and reflow operations.
In addition to the standard values shown, custom induc-
tors are also available.
