USB 2.0 Common Mode Filter

Specifications subject to change without notice. Document 386-1 Revised 08/20/04
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 30 dB
common mode attenuation and greater than 100 ohms
impedance.
These dual-wound filters have an industry standard
footprint and feature lower DC resistance and greater
current handling capability than our 0805USB filter.
They are available in nine values to meet your specific
requirements.
Coilcraft Designer’s Kit C184 contains samples of all
values shown here plus all values in our 0603USB and
0805USB series. To order, contact Coilcraft or purchase
online at http://order.coilcraft.com.

1. When ordering, please specify packaging code:
1206USB-113MBC
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. Average current for a 20°C rise from 25°C ambient.
4. DCR and Irms are specified per winding.
5. Operating temperature range 40°C to 85°C.
6. Electrical specifications at 25°C.
