Product details

Board-to-Wire Header for 2.54 mm Pitch MTA-100 Systems

It mates with standard MTA-100 crimp receptacles for a board-to-cable/wire connection. Surface mount termination suits reflow assembly, saving a wave-solder pass compared to through-hole headers.

SMT Footprint and Routing Notes

The shrouded wall on one side protects the mating pins from bent-contact damage during blind mating.
