It uses a 3.00mm pitch, carries an 8A per-circuit rating at 600V, and terminates through-hole with a right-angle orientation — placing the mating face parallel to the PCB for edge-mounted harness connections. The header is fully shrouded with four walls, protecting the male pins during mating and preventing bent contacts in field service. A locking ramp on the housing provides audible positive retention with the matching receptacle, and the integrated board lock holds the part in place during wave soldering and resists shear forces from cable strain. ## What the Ratings Mean for Your Fit The 8A per-circuit rating is the headline power figure — at 3.00mm pitch, that current density is typical for a mid-power interconnect, suited for distribution rails inside a control cabinet or power supply output, not just signal lines. The 600V voltage rating gives generous creepage margin on the 3.00mm pitch for industrial and telecom gear, where transient spikes are common. The 15.0µin gold plating on the mating contacts is the key durability spec: gold at this thickness handles repeated mating cycles in field-serviceable applications without the fretting corrosion you'd see with tin on a frequently unmated connection. The board lock is a practical feature for automated assembly — it holds the header in place during wave solder and resists the shear force from a cable bundle tugging on the mated receptacle. ## Where It's Used This header is specified across automotive, general-purpose industrial, medical, and telecommunications equipment. The -40°C to 105°C operating range qualifies it for outdoor telecom cabinets, automotive underhood compartments, and unheated industrial enclosures. The UL94 V-0 housing meets the flame-rating requirement for equipment inside an enclosure — a compliance gate for medical and industrial control panels. The locking ramp and board lock together make it suitable for high-vibration environments like machinery or vehicle body controllers. ## Mating and Termination The 430450622 mates with the Micro-Fit 3.0 receptacle housings (e.g., the 43025 series) using the matching crimp terminals. The right-angle orientation places the receptacle entry parallel to the board, which is the standard layout for wire-to-board harnesses exiting at the board edge. The through-hole solder tails are 0.125\" (3.18mm) long, suitable for standard 1.6mm PCBs with through-hole wave soldering. The dual-row configuration at 0.118\" (3.00mm) row spacing gives a compact footprint — 6 positions in two rows of three.","metaTitle":"Molex Micro-Fit 3.0 430450622, 6-Circuit Header, 8A","metaDescription":"Molex 430450622 Micro-Fit 3.0 6-circuit right-angle header, 3.00mm pitch, 8A, 600V, gold contacts, board lock, UL94 V-0.
