1. When ordering, please specify packaging code:
MSS7341-104MXD
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.
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.
Coilcraft Designer’s Kit C185 contains samples of all
values shown. To order, contact Coilcraft or purchase
