SMT Power Inductors –MSS7341 Series
The MSS7341 series is ideal for applications requiring
high power and high efficiency such as notebook com-
puters, wireless phones, PDAs and other handheld
products. It provides excellent current handling capabil-
ity in a rugged, low cost part.
These magnetically shielded power inductors are de-
signed for high-density mounting and are available on
tape and reel for auto-insertion. They are offered in 18
inductance values from 3.3 to 100 µH including values
not available in our other power inductor series.

Packaging: D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape (1200 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 D instead.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4284A impedance analyzer.
3. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
4. DC current at which the inductance drops 25% (typ) from its value without
current.
5. Average current for temperature rise above 25°C ambient.
6. Storage and ambient operating temperature range
−40°C
to +85°C.
7. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
