Board-edge wire-to-board header with locking ramp
The 2-1445091-5: This is a 5-position, single-row Micro MATE-N-LOK header from TE Connectivity AMP Connectors, designed for board-to-cable/wire applications. The 3.00 mm pitch sets the PCB footprint and the per-contact current ceiling — at the rated voltage of 250 V, the current is limited by wire gauge, not the header itself. The right-angle SMD orientation places the mating axis parallel to the board, ideal for board-edge routing where z-height is tight. The shrouded 4-wall housing protects the male pins during handling and guides the mating receptacle into alignment. A locking ramp on the header engages with the matching receptacle latch, providing positive retention under vibration — a common requirement in industrial and automotive harnesses.
Gold mating surface and solder retention
The mating contacts are finished with 15 µinch gold over nickel, rated for repeated mating cycles without corrosion. The solder tails are tin-plated (100 µinch) for reliable wetting to the PCB pad. Solder retention features on the housing help hold the header in place during reflow, reducing tombstoning risk.
