Low-profile common mode choke for super speed signal lines
Coilcraft’s noise suppression 0805USBN Series common mode chokes measure 2.0 x 1.2 mm, with a maximum height of 0.93 mm, making them the lowest profile 0805 common mode chokes available.

They offer up to 6.5 GHz differential mode 3 dB cutoff frequency and up to 35 dB common mode noise attenuation across a wide frequency range up to GHz band, suiting them for noise suppression in super high speed signal lines such as USB 3.x, HDMI 2.0, HDBaseT, DisplayPort, and DVI. They are also suitable for high speed differential signal lines such as USB 2.0, IEEE1394, and LVDS and are compatible with the USB Type-C specification 1.0.

The 0805USBN Series also offers very low DCR (0.11 to 0.63 Ohms) and current ratings up to 0.5A. It is available in eight impedance values to meet specific design requirements. They have an ambient temperature rating of -40°C to +125°C.
