1. When ordering, please specify packaging code:
MSS7341-104MX
D
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 25C ambient.
6. Storage and ambient operating temperature range
-40C to +85C.
7. Electrical specifications at 25C.
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 H 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
online at http://order.coilcraft.com.
