The Molex 0430450206 is a 2-circuit member of the Micro-Fit 3.0 43045 series, a shrouded header for board-to-wire power and signal interconnects. It carries 8 A per contact at 600 V, with tin-plated square pins on a 3.00 mm pitch across two rows. The SMT right-angle orientation and integrated board lock suit it for automated assembly in space-constrained or vibration-prone environments — automotive, industrial, medical, and telecom applications are listed.
The 8 A per circuit rating is the headline current for the Micro-Fit 3.0 contact system at a 30 °C temperature rise — adequate for moderate power distribution or a single signal pair. The 600 V rating, combined with the 3.00 mm pitch and full 4-wall shrouding, provides enough creepage for industrial and telecom bus voltages without forcing an oversized board footprint. The locking ramp provides an audible latch with the matching receptacle housing, preventing accidental unmating in automotive or industrial harness runs.
