Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 6 Contact, 3 mm Pitch, 2 Row, Shrouded 43045-0612

The Molex 43045-0612 Micro-Fit 3.0 Series Straight Through Hole PCB Header is designed for reliable wire-to-board connections in industrial and commercial electronic systems. Featuring 6 gold-plated brass contacts spaced at a 3 mm pitch across two rows, this shrouded header supports currents up to 8.5 A and a voltage rating of 250 V, making it ideal for low to mid-range power and data transfer.

The housing is made from high-temperature thermoplastic resin with UL 94V-0 Liquid Crystal Polymer rating, able to withstand reflow soldering temperatures up to 265°C. Polarised pegs and a raised ramp locking mechanism ensure secure mating with corresponding Micro-Fit receptacles, reducing risks of disconnection or misalignment.

Mounting is through-hole style, offering solid PCB attachment and compatibility with SMT processes, which reduces manufacturing costs. The tin-plated brass contacts resist corrosion and offer durability in various operating environments, withstanding temperatures from -40°C to 105°C.

This PCB header is commonly used in a range of industrial applications including office and industrial automation equipment, consumer white goods, rack-mount servers, routers, and switches. It is a compact, efficient connector solution for power distribution and signal integrity in electronics assemblies.

The header supports up to 8.5 A current for efficient low to mid-range power distribution. Constructed with high-temperature thermoplastic housing and brass contacts plated with tin for corrosion resistance. Polarised pegs ensure correct mating alignment, preventing incorrect connections.

Raised ramp and shrouded terminal design secure the Micro-Fit receptacle latch and protect contacts from damage. Suitable for applications including consumer white goods, industrial automation, office equipment, routers, and rack-mount servers.

The straight through-hole mount provides robust mechanical and electrical connection to printed circuit boards.
