USB 2.0 Common Mode Choke
0805
Eliminates virtually all common mode noise in high-speed, dif-
ferential mode signal transmission applications such as USB 2.0,
IEEE1394, HDMI and LVDS. Most provide >25 dB common
mode attenuation and >100 ohms impedance.
Designer’s Kit C384
contains 10 each of all 0603USB, 0805USB
and 1206USB parts

1. When ordering, please specify
packaging
code:
0805USB-902MLC
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel).
B
= Less than full reel. In tape, but 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 plas-
tic tape (7500 parts per full reel).
2. Inductance measured at 100 MHz using an Agilent/HP 4286A
impedance analyzer and a Coilcraft SMD-A fixture.
3. DCR is specified per winding.
4. Current per winding that causes a 20°C rise from 25°C ambient.
5. Operating temperature range
−40°C
to 85°C.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
