Common Mode Chokes Have Low Profile

20 May 2016

Coilcraft’s0805USBN Series common mode chokes measure just 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 as ideal for noise suppression in super-high-speed signal lines such as USB 3.x, HDMI 2.0, HDBaseT™, DisplayPort and DVI. The chokes are also suited for high-speed differential signal lines such as USB 2.0, IEEE1394, and LVDS, and are compatible with 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 0.5 amps. It is available in eight impedance values to meet specific design requirements. All 0805USBN common mode chokes are halogen free and feature RoHS-compliant matte tin over nickel over silver-platinum-glass frit terminations. They have an ambient temperature rating of -40° C to +125° C.
