Chokes Rise To The Superspeed USB 3.0 Noise Challenge


Coilcraft’s new common mode chokes measure just 2.0 mm x 1.2 mm, with a maximum height of 0.93 mm, making them the lowest profile 0805 common mode chokes available. Applications include noise suppression in super high speed signal lines: USB 3.x, HDMI 2.0, HDBaseT, DisplayPort, DVI, etc., and in high speed differential signal lines: USB 2.0, IEEE1394, LVDS, etc.

The 0805USBN series offers 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,

The chokes also offer very low DCR (0.11 to 0.63 Ohms) and current ratings up to 0.5 Amps. They are available in 8 impedance values to meet specific design requirements.

Further, the devices are halogen free and feature RoHS compliant matte tin over nickel over silver-platinum-glass frit terminations. Ambient temperature rating is specified from -40°C to +125°C.

The 0805USBN series is available now. For further information, click here.
