usb 2.0 common mode filter C 0805 document 306-1 specifications subject to change without notice. document 306-1 revised 12/15/03 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. m ost provide greater t han 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. to request free evaluation samples, contact coilcraft or visit www.coilcraft.com . common mode common mode impedance typ (ohms) attenuation typ (db) inductance 2 dcr max i rms 3 part number 1 10 mhz 100 mhz 500 mhz 10 mhz 100 mhz 500 mhz 20% (nh) (ohms) (ma) 0805usb-421xmb_ 14 42 70 1.1 2.3 8.4 33 0.12 500 0805usb-901xmb_ 28 90 154 1.4 4.2 16.9 68 0.17 500 0805usb-172xmb_ 57 170 303 2.3 6.7 22.0 120 0.25 500 0805usb-262xmb_ 85 260 435 3.0 8.6 27.8 210 0.26 500 0805usb-372xmb_ 118 370 641 4.5 11.9 34.3 270 0.32 500 0805usb-502xmb_ 148 500 945 4.9 14.5 31.3 390 0.37 500 0805usb-672xmb_ 246 670 1231 8.4 16.6 30.0 460 0.45 500 0805usb-902xmb_ 294 900 1715 8.7 18.7 30.5 560 0.65 400 1. specify packaging code: 0805usb -902xmb 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. average current for a 20c rise from 25c ambient. 4. dcr and i rms are specified per winding. 5. operating temperature range ? 40c to 85c. 6. electrical specifications at 25c. 1 3 2 4 tape and reel: 2000/7 reel; 7500/13 reel 8 mm tape width for packaging data see tape and reel specifications section.
