Stephen Law
Electronics Engineering choke common mode chokeCOILCRAFT 0805USBN Series common mode chokes measure 2.0 x 1.2mm, with a maximum height of 0.93mm. Devices provide up to 6.5GHz differential mode 3dB cutoff frequency and up to 35dB common mode noise attenuation across a wide frequency range up to GHz band, making them suitable for noise suppression in super high speed signal lines such as USB 3.x, HDMI 2.0, HDBaseT, DisplayPort, and DVI. Devices provide low DCR (0.11 to 0.63 Ohms) and current ratings up to 0.5 Amps. Product comes in 8 impedance values and are halogen free, featuring RoHS compliant matte tin over nickel over silver-platinum-glass frit terminations. http://www.coilcraft.com/0805usbn.cfm
