USB 2.0 Common Mode Choke – 0603
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 15 dB
common mode attenuation and greater than 100 ohms
impedance.
These low profile parts are designed for applications
where space is at a premium, requiring less than half the
board space of our 0805USB filters.
These dual-wound filters feature very low DC resistance
and are available in five impedance 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
0805USB series. To order, contact Coilcraft or purchase

1. When ordering, please specify
packaging
code:
0603USB-222MLC
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.
