Document 306-1
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

Ambient temperature  –40°C to +85°C with Irms current
Storage temperature  Component: –40°C to +85°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat  Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL)  1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
PCB washing  Tested with pure water or alcohol only. For other solvents,

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.
