USB 2.0 Common Mode Filter –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.
To request free evaluation samples, contact Coilcraft or
