Document 386-1 USB 2.0 Common Mode Choke – 1206 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 C384 contains samples of all values shown here plus all values in our 0603USB and 0805USB series.

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. 250 250 250 250 250 250 250 250 250 Irms4 (mA) 1000 850 700 600 600 600 500 500 500 2 1 3 4 0.072 ±0.004 1,83 ±0,10 0.028 0.070 0,71 1,78 1 0.006 0,15 0.038 0,97 0.064 1,63 2 1 3 4 0.015 0,38 2 0.063 ±0.004 1,60 ±0,10 4 3 0.024 0,61 Recommended Land Pattern 0.026 0,66 Terminations: Gold over nickel over silver-palladium-glass frit Weight: 36.2 – 37.6 mg Tape and reel: 2000/7″ reel; 7500/13″ reel 8 mm tape width For packaging data see Tape and Reel Specifications section.
