• High-density 1.27 mm pitch architecture

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections
• Mezzanine circuit stacking
• Compact electronic module assembly

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure that the vertical orientation and SMT footprint requirements align precisely with the target PCB layout. Confirm that the 1.27 mm pitch and 40-position configuration match the system design specifications to avoid mechanical incompatibility during assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a vertical, low-profile connection is required between stacked boards. The 1.27 mm pitch offers a balance between density and manufacturability. Consider the 1.2 A current rating and 100 VAC voltage limit to ensure they meet the electrical demands of the application. The LCP housing provides thermal stability suitable for reflow soldering processes.
