Backlight Inductors - DS1608BL Series
These tiny shielded inductors are specially engineered for
demanding backlighting applications. They feature high
breakdown voltage and exceptional efficiency: DC resis-
tance 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.
Coilcraft Designer’s Kit C134 contains samples of all
values. Visit http://order.coilcraft.com to order on-line.
