3.00mm pitch, 3-position SMT header with locking ramp
The 2-1445053-3 is a 3-position, single-row header from TE's Micro MATE-N-LOK series, designed for board-to-cable/wire connections. Its 3.00mm pitch sets the PCB footprint and the contact spacing for the mating receptacle. The shrouded 4-wall housing protects the male pins during handling and guides the plug into alignment. The locking ramp provides a positive mechanical latch against the mating housing, so the pair stays mated under vibration — you should hear it click when it seats. Surface-mount termination with pick-and-place features and solder retention pads makes it suitable for automated reflow assembly.
Tin-plated contacts rated for general-purpose duty
Tin plating is cost-effective for moderate mating cycles — expect several dozen to a few hundred cycles in a clean, dry environment. The square male pins are brass, a common base metal for good spring properties and conductivity. Current rating varies by wire gauge used in the mating half, but the header itself is designed for the Micro MATE-N-LOK system's signal-level currents. Voltage rating is 250V.
