SMT Power Inductors – Series MSS1038
The MSS1038 series provides very high efficiency and
excellent current handling capability in a rugged, low cost
part. The magnetic shielding, small footprint and low profile
allow high density mounting. The flat top ensures reliable
pick and place handling.
These inductors are ideal for use in DC-DC converters,
LCD panels, and portable devices where low cost and high
reliability are critical. They are available in 31 inductance
values from 1.0 µH to 1000 µH.
