1206USB Series

Common Mode Choke

RoHS compliant halogen free
Our 1206USB Series was designed for common mode noise suppression in high-speed differential signal lines (USB2.0, IEEE1394, and LVDS) for up to 2.7 GHz differential mode 3 dB cutoff frequency. It provides up to 2.24 kOhms common mode peak impedance and 33 dB common mode noise attenuation.
  • For common mode noise suppression in high-speed differential signal lines: USB2.0, IEEE1394, LVDS, etc.
  • For USB 3.x applications, consider our 0603USB0805USBF or 0805USBN series
  • Up to 2.7 GHz differential mode 3 dB cutoff frequency
  • Up to 2.24 kOhms common mode peak impedance and 33 dB common mode noise attenuation
Refer to Designing Common Mode Filters for design guidance.

Notes
  1. When ordering, please specify packaging code: e.g. 1206USB-223MLC
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance measured at 100 MHz, with windings connected in parallel, using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture.
  4. Irms: Current per winding that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. 250 Vrms, 1 minute interwinding isolation (hipot).

Termination:

  • Gold over nickel over silver-palladium-glass frit.

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (2000 per full reel).
  • B = Less than full reel
    In tape, not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13" machine-ready reel
    EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
