SMT Power Inductors - MSS Series
The MSS series is ideal for applications requiring high
power and high efficiency such as notebook computers,
PC cards, cellular phone handsets, and handheld prod-
ucts. These magnetically shielded, low-profile power
inductors are designed for high-density mounting and are
available on tape and reel for auto-insertion. Their indus-
try-standard shape and flat-top design ensures reliable
pick and place handling.
They are available in three families with inductance
ratings from 2.2 to 390 µH. These inductors can handle
current as high as 1.9 Amps and offer DC resistance as
low as 0.023 Ohms.
Samples of all values are available in Coilcraft
Designer’s
Kits.

Packaging code:
C
=
7″ machine-ready reel
EIA-481 embossed plastic tape (400 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. Factory
order only, not stocked (1500 per reel per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. SRF measured using Agilent/HP 4191A or equilvalent.
4. DC current at which the inductance drops 10% (typ) from its value without
current.
5. Average current for temperature rise above 25°C ambient.
6. Operating temperature range
−40°C
to +85°C.
7. Electrical specifications at 25°C.
