Document 306-1 USB 2.0 Common Mode Choke 0805 Eliminates virtually all common mode noise in high-speed, differential 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 Core material Ferrite Environmental RoHS compliant, halogen free Terminations Gold over nickel over silver-palladium-glass frit. 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 to MIL-STD-202 Method 215 plus an additional aqueous wash.

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 plastic 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.
