SMT Power Inductors - DS5022 Series
The DS5022 Series is a family of magnetically shielded
power inductors designed for the higher current require-
ments of portable computers, video recorders and other
DC-DC conversion applications.
They feature saturation current ratings as high as 8 Amps
and rms current ratings up to 3.9 Amps. Low DC resis-
tance (as low as 0.040 Ohms) keeps power losses to a
minimum.
Designed specifically for surface mounting, the DS5022
has a flat top for reliable pick and place operations. The
terminals wrap around the end of the base to ensure a
sound solder fillet and simplify inspection.
