These Coilcraft filters are designed to eliminate virtually
all common mode noise in high-speed, differential mode
signal transmission applications such as USB 2.0,
IEEE1394 and LVDS. Most provide greater than 25 dB
common mode attenuation and greater than 100 ohms
impedance.
The low profile design and standard 0805 footprint make
it the ideal solution for designs where board space is at
a premium.
These dual-wound filters feature very low DC resistance
and are available in eight values to meet your specific
requirements.
Coilcraft Designer’s Kit C384 contains samples of all
values shown here plus all values in our 1206USB and
0603USB series. To order, contact Coilcraft or purchase

1. When ordering, please specify packaging code:
0805USB-902ML
C
Packaging: C =7
″ machine-ready reel. EIA-481 embossed plastic
tape (2000 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 C instead.
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape (7500 parts per full reel).
2. Inductance measured at 100 MHz using an Agilent/HP 4286A
impedance analyzer and a Coilcraft SMD-A fixture.
3. DCR is specified per winding.
4. Current per winding that causes a 20°C rise from 25°C ambient.
5. Operating temperature range
−40°C to 85°C.
6. Electrical specifications at 25°C.
