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.
Free evaluation samples are available by contacting Coil-
craft or on the web at

1. When ordering, please specifypackaging code:
MSS1038-105NXC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 parts per full reel).
B
= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape (1000 parts per full reel).
Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc.
SRF measured using an Agilent/HP 4192A or equivalent.
DC current at which the inductance drops 35% max from its value
without current.
Average current for temperature rise from 25°C ambient.
Operating temperature range –40°C to +85°C.
Electrical specifications at 25°C.
