Round Conductor Flat Cable
.025" 30 AWG Stranded, TPE
• .025 inch wire spacing increases signal density
• TPE insulation provides excellent transmission
properties
• 30 AWG stranded conductors on .025 inch wire
spacing is designed for mass termination and
flexibility
• Meets the SCSI-3 characteristic impedance
requirements
• See the Regulatory Information Appendix
(RIA) in the “RoHS compliance” section of
www.3Mconnectors.com for compliance
information (RIA E1 & C1 apply)
