Product details

The SM12B-GHS-TB(LF)(SN): The tin-plated mating finish keeps cost down for applications with moderate mating cycles, such as once during assembly and occasional field service.

Board Layout and Termination Details

This is a surface-mount, right-angle header with solder termination. The insulation height of 0.167 inches (4.25 mm) gives clearance for the mating receptacle's latch. The rectangular contact shape and phosphor bronze base material provide consistent spring force over the rated temperature range of -25°C to 85°C.
