Document 406-1 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.

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.
