Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 10 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-1013

Molex 43045-1013 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a high-performance dual row connector with 10 contacts and a 3 mm pitch designed for wire-to-board applications. This shrouded PCB header features gold-plated brass contacts within a high temperature thermoplastic housing that withstands up to 265°C during the IR reflow soldering process, ensuring robust mechanical and electrical performance.

The connector supports up to 5A current and a voltage rating of 250V, making it suitable for low to mid-level power distribution in electronic assemblies. Its straight orientation and through-hole mounting provide mechanical strength and stability on the PCB, while SMT compatibility offers manufacturing flexibility.

The Micro-Fit 3.0 Series includes features such as PCB polarizing pegs to aid accurate connector positioning and kinked solder legs for additional board retention. The positive latching mechanism ensures secure mating and prevents unintended disconnection, critical for reliable system operation.

Constructed with precision brass contacts plated in gold, these connectors afford excellent conductivity and corrosion resistance. The fully isolated contact design further reduces potential electrical arcing, enhancing safety and longevity.

Designed for applications including consumer appliances like dryers and refrigerators, data communication equipment such as routers and servers, medical devices, telecommunications setups, solar power systems, and military commercial off-the-shelf (COTS) products, this connector offers a versatile and compact power connection solution.

The housing material is a UL 94V-0 liquid crystal polymer thermoplastic rated for high-temperature endurance. The connector system facilitates wire-to-board connectivity with a pitch of 3 mm and dual rows for density optimization.

Contact lengths are designed for reliable PCB insertion and solder joint integrity. Operating temperatures span from -40°C to 125°C, enabling use in demanding environments. This product does not carry specific standards or approvals but meets general quality and safety requirements.
