The Molex 48338 PCI Express ® Mini Card Connectors are top-mount, right angle connectors with eleven mounting height choices from 4.00mm to 9.99mm for design flexibility and cost savings. Modeled after and replacing the Mini PCI Type III card , the Molex 48338 connectors provide stable normal force, low contact resistance, and reliable, high-speed signal transmission. The Molex 48338 PCI Express Mini Card Connectors are ideal for high signal integrity wired or wireless applications such as notebook PCs, netbooks, and data communication devices.

• Connectors meet the PCI Express® Mini Card Electromechanical Specification Revision 1.2 and and satisfy performance characteristics required to address system manufacturers' needs
  
• Extensive range of 4.00 (.157") to 9.90mm (.390") height connectors configurable to the customers' needs provide complete design flexibility and support for low- to high-profile applications
  
• Small connector footprint provides significant PCB real estate savings
  
• Tight-fitting reinforced housing ribs between the SMT terminals prevent bent pins while ensuring linearity and accurate positioning of the blade-type SMT terminals
  
• Staggered SMT terminal design on each side of connector body enhances signal integrity (SI) performance and minimizes cross-talk
  
• High temperature thermoplastic used offers halogen-free benefits; ability to withstand IR reflow process
  
• SMT soldertab on each side of connector provides robust connector hold-down to PCB
  
• Beveled, dual-sized locating pegs customizable to ‘crush-rib’ types ensure correct connector-to-PCB polarization; optional ‘crush-rib’ pegs provide greater PCB retention during soldering process
  
• Polarization key prevents mis-mating upon insertion of PCB module into the connector
  
• Wide 35-degree PCB module entry angle allows greater ease-of-use with less restriction on the insertion angle of the PCB module

This low-profile 4.00mm height connector offers excellent vertical space-savings for low-profile wired or wireless communication applications. The high-profile height of the 9.90mm height connector provides vertical clearance beneath the PCB module for placement of electronic components onto the PCB in tight electronic packaging situations.
