It is a surface-mount, right-angle male pin header with a 3.00 mm pitch, shrouded on all four walls, and uses a locking ramp fastening system for secure mating. The 8 A per circuit current rating and 600 V voltage rating place it firmly in the power interconnect category, not signal-only duty. Gold plating on the mating contacts (15.0 µin) supports repeated mating cycles, while the tin post finish is standard for solder termination. Applications include automotive, general purpose, industrial, medical, and telecommunications equipment. ## What the ratings mean for your fit The 3.00 mm pitch and 0.118\" row spacing define the PCB footprint — this is a standard Micro-Fit 3.0 layout, so if your board already has that pattern, the footprint is a drop-in. The 8 A per circuit rating is the per-contact limit at the connector; the actual current your system can carry depends on the number of circuits used in parallel and the ambient temperature up to 105°C. The 15.0 µin gold on the mating side is a mid-grade plating — it handles regular mating cycles in a production or field-service environment without the cost of heavy gold. The board lock feature holds the header in place during reflow and resists shear forces from the cable assembly after mating. ## Mating and termination This header mates with any standard Micro-Fit 3.0 receptacle housing (the 43025 series) using the matching crimp terminals. The locking ramp on the header engages with the latch on the receptacle for a positive, vibration-resistant connection. Termination is SMT solder — the right-angle orientation places the pins parallel to the board surface, which is typical for board-edge or low-profile cable exits.","metaTitle":"Molex Micro-Fit 3.0 430451007, 10-Pin SMT Header, 3mm Pitch","metaDescription":"Molex 430451007 Micro-Fit 3.0 header, 10 circuits, 3.00mm pitch, SMT right-angle, 8A, 600V, gold plating, board lock.
