1.27mm (.050”) Pitch EBBI™ 50D Receptacles FEATURES AND SPECIFICATIONS 71743 SCA-2, SMT, Vertical Surface Mount SCA-2 Receptacles Maximize Board Space For Higher Density Requirements Compared to Through-Hole Versions Molex’s SCA-2 Surface Mount Technology (SMT) receptacles feature surface mount leads, designed to increase usable board space beneath the connector. Double-sided boards can be used as a result of SMT versus through-hole leads, providing increased density. The SMT receptacles are available in 40 and 80 circuit versions, commonly found in Fibre Channel and other drive configurations for storage applications. SCA-2 SMT receptacles include all of the features found in Molex’s standard range of SCA-2 products. SCA-2 connectors meet the requirements of the SCA-2 Single Connector Attach specification for small form factor disk drives. For additional information on this specification, visit: www.scsita.org.
