3M™ Round Conductor Flat Cable
.025" 30 AWG Solid, TPE 3749 Series
• Close spacing permits higher signal density
• TPE insulation provides excellent transmission
     properties
• 30 AWG solid conductors on .025 inch spacing
     allows for mass termination
• Zippable for branching or discrete termination
• Meets SCSI-3 Fast-20 characteristic impedance
    requirements
• See the Regulatory Information Appendix (RIA) in
     the “RoHS compliance” section of
     www.3Mconnector.com for compliance information
    (RIA E1 & C1 apply)
