Web Sample Tools & Support Document 215 -1 page & buy software & FAQ IEEE 1394 Common Mode Choke Designed for IEEE 1394 and other high-speed twisted pair AEC + Q200 85C interfaces. Shielded 1812 size filter Provides over 21 dB attenuation of common mode noise at 400 MHz with a cutoff frequency of 1.2 GHz Core material Ferrite Terminations RoHS compliant gold over nickel over moly-manganese Weight: 30 mg Ambient temperature 40C to +85C with Irms current. Maximum part temperature +100C (ambient + temp rise). Storage temperature Component: 40C to +100C. Tape and reel packaging: 40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) Packaging 600/7 reel 2200/13 reel Plastic tape: 12 mm wide, 0.25 mm thick, 8 mm pocket spacing, 3.9 mm pocket depth PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

When ordering, please specify packaging code: C B E D 4 1 CM1394LC Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic 1 4 tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). A F D = 13 machine-ready reel. EIA-481 embossed plastic 2 3 tape (2200 parts per full reel). B = Less than full reel. In an effort to simplify our part H numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply G change the last letter of your part number from B to C. 2 Frequency at which the differential mode attenuation equals 3 dB 0.015 0.057 3.
