CM1394 Series

IEEE1394 Common Mode Choke

RoHS compliant
Our CM1394 Series common mode choke was designed for IEEE1394 and other twisted-pair interfaces. It provides common mode and differential mode filtering in a single device with more than 21 dB attenuation at 400 MHz and is less expensive than hand-wound toroid designs.
  • Designed for IEEE1394 and other twisted-pair interfaces
  • Common mode and differential mode filtering in a single device
  • More than 21 dB attenuation at 400 MHz
  • Less expensive than hand-wound toroid designs
  • Defense Supply Center CID A-A-59744

Notes
  1. When ordering, please specify packaging code: e.g. CM1394LC
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance measured at 100 MHz.
  4. Irms: Current per winding that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Winding to winding isolation (hipot) tested for one minute.
