2-1445055-9 is a single-row vertical header connector in the Micro MATE-N-LOK 3mm connector system designed for wire-to-board connections. The header supports 2-12 positions with 3mm (0.118 inch) centerline spacing and is available in both through-hole and surface mount (SMT) configurations with SMT hold-down and metal hold-down options. It features 15 µm gold plating on contacts, retention bumps on the solder tail, and is compatible with contacts rated for wire sizes 18-30 AWG with insulation diameters up to 2.79 mm. The connector supports current ratings up to 5 Amps per line and is infrared (IR) reflow process compatible. This header is commonly used in applications requiring reliable wire-to-board interconnections in consumer electronics, industrial equipment, and automotive systems where compact spacing and high-density connections are needed.
