Backlight Inductors - DS1608BL Series
Thesetinyshieldedinductorsarespeciallyengineeredfor
demanding backlighting applications. They feature high
breakdownvoltageandexceptionalefficiency:DCresis-
tance is 10% to 60% lower than other inductors.
Thesemagneticallyshieldedinductorsaredesignedwith
a flat top and constructed of heat resistant materials to
ensuretrouble-freeassemblyandreflowoperations.
In addition to the standard values shown, custom induc-
tors are also available.
Coilcraft Designer’s Kit C134 contains samples of all
