USB 2.0 Common Mode Choke –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 C384 contains samples of all
values shown here plus all values in our 1206USB and
0603USB series. To order, contact Coilcraft or purchase
online at http://order.coilcraft.com.
