0805USBF Series

Low Profile Common Mode Chokes

Our 0805USBF Series common mode chokes are great for noise suppression in ultra-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, and LVDS). They are also suitable for USB-type C specification 1.0 and provide up to 6.0 GHz differential mode 3 dB cutoff frequency and up to 30 dB common mode noise attenuation in the GHz range.

For noise suppression in ultra 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.
Up to 6.0 GHz differential mode 3 dB cutoff frequency
Up to 30 dB common mode noise attenuation in GHz range
Suitable for USB-type C specification 1.0
AEC-Q200 Grade 1 (−40°C to +125°C)

Notes

When ordering, please specify packaging code: e.g. 0805USBF-902MRC
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 15°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:

Matte tin 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).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (7500 parts per full reel).
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.
