Document 306-1 USB 2.0 Common Mode Filter – 0805 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 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. Coilcraft Designer’s Kit C184 contains samples of all values shown here plus all values in our 1206USB and 0603USB series.
