Product Description
Molex 43045-1414 Micro-Fit 3.0 Series straight through hole PCB header connector offers a compact and reliable solution for low to mid-range power distribution in electronic systems. This model features 14 male contacts arranged in two rows with a 3 mm pitch, housed within a thermoplastic casing compliant with high temperature IR reflow soldering processes. Its shrouded design and positive latching ensure secure and stable connections.
The connector supports currents up to 5 amperes and operates efficiently across a wide temperature range from -40°C to 125°C, making it suitable for demanding industrial and commercial environments. The gold-plated brass contacts provide excellent conductivity and resistance to corrosion, while the through hole mounting method allows robust PCB attachment with SMT compatibility for streamlined manufacturing.
Additional design features include PCB polarizing pegs for precise positioning and kinked solder legs that enhance board retention during soldering and operation. The isolative dual beam terminals minimize arcing risks, improving overall reliability.
This Micro-Fit 3.0 header series is widely used in military commercial off-the-shelf (COTS) assemblies, solar power systems, consumer products such as dryers and refrigerators, data communications including routers and servers, medical equipment, telecommunications hardware, and gaming consoles. Its versatility and robust construction make it a key component in various industrial, laboratory, and commercial electrical assemblies.
Supports high current in a compact footprint for efficient power connectivity. Thermoplastic high temperature housing withstands IR reflow soldering. Dual row, 14-contact, 3 mm pitch configuration for dense wiring setups.
Gold-plated brass contacts for excellent electrical performance and durability. Positive housing latching ensures secure and stable mate connections. Through hole mounting with SMT compatibility reduces assembly complexity.
PCB polarizing pegs and kinked solder legs aid alignment and mechanical retention. Wide operating temperature range from -40°C to 125°C for varied applications.
