Document 378-1 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 30 inductance values from 1.5 µH to 1000 µH. Coilcraft Designer’s Kit C391 contains samples of all values shown.
