Low-profile connectors save space on PCI cards

Molex reckons its 124-pin Type III MiniPCI connectors are an ideal way to optimise PCB real estate savings.

Molex reckons its 124-pin Type III MiniPCI connectors are an ideal way to optimise PCB real estate savings.

These 0.8mm pitch SMT connectors feature low-profile mounted height options of 4.0 and 5.2mm to ease vertical space constraints and give greater design flexibility for LAN and modem card makers.

A characteristic feature of these connectors is Molex's patented anti-overstress feature that protects the latch from breakage caused by bending it too far out or in.

Plastic latches help prevent scratching of memory module.

Molex offers these connectors in four series: 67315 and 67437 - which have a profile height of 4.0mm; and series 67391 and 67440 - which are 5.2mm variants.

The connectors are available with or without grounding clips.

Series 67315 and 67391 have front solder tabs for optimal PCB hold-down, while series 67437 and 67440 have PC tabs formed from a single-piece metal of the nail on each arm of the connector.

The connector's stamped-and-formed contacts provide good contact wipe and electrical continuity.

The absence of any 'sharp or cut' edges ensures no damage to the module.

Gang-load assembly of the contacts provides excellent coplanarity control of 0.1mm.

The connector's housing is made of glass-filled high temperature thermoplastic to withstand IR reflow temperatures.

Customers can order the connectors in soft- or semi-hard tray, and tape-and-reel packaging.
