CM1394LC

Document 215 -1 IEEE 1394 Common Mode Choke The CM1394 provides a low cost, high performance way to virtually eliminate common mode noise from IEEE 1394 and other high-speed twisted pair interfaces. It provides over 17 dB attenuation of common mode noise at 400 MHz while differential mode signals extend out to 800 MHz before reaching the 3 dB point. This shielded, 1812 size filter is machine wound, making it less expensive than hand-wound toroid designs. It also assures tighter tolerances between windings for excellent impedance balance. Coilcraft’s CM1394 meets the IEEE 1.5 Amp Irms specification and has a maximum DCR of 0.105 Ohms. To request free evaluation samples, contact Coilcraft or visit www.coilcraft.com.
