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.
Coilcraft Designer’s Kit C185 contains samples of all
values shown. To order, contact Coilcraft or purchase
online at http://order.coilcraft.com.
