The Molex 430451024 is a 10-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects. It carries 8 A per circuit at 600 V on a 3.00 mm pitch, with tin-plated mating contacts (60.0 µ" thickness) and tin-plated solder posts. The through-hole kinked-pin termination provides secure PCB retention, while the 4-wall shrouding with a locking ramp protects the mating interface and resists vibration.
The 8 A per circuit rating at 600 V is specified for the connector.
Mating and Assembly
This header mates with Micro-Fit 3.0 receptacle housings using the corresponding crimp terminals. The locking ramp provides audible feedback on full engagement.
Applications and Environment
Rated for -40°C to 105°C with a UL94 V-0 flammability rating, the 430451024 is suited for automotive, industrial, medical, and telecom equipment where the connector sits inside an enclosure. The LCP housing withstands lead-free reflow temperatures, making it compatible with standard SMT assembly lines despite being a through-hole part. The board lock adds vibration resistance for applications in automotive or industrial machinery.
