1206USB Series

Common Mode Choke

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 0603USB, 0805USBF 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

When ordering, please specify packaging code: e.g. 1206USB-223MLC
Frequency at which the differential mode attenuation equals 3 dB
Inductance measured at 100 MHz, with windings connected in parallel, using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture.
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.
DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
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 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (7500 parts per full reel).
