Molex Micro-Fit 3.0 Series Straight Surface PCB Header 14 Contact 3 mm Pitch 2 Row Shrouded 43045-1418

Molex 43045-1418 Micro-Fit 3.0 Series straight surface PCB header is a compact dual-row connector designed for high reliability in power distribution on printed circuit boards. With a pitch of 3 mm and 14 male contacts arranged in 2 rows, this header supports currents up to 5 amps and voltages up to 250 volts, making it perfectly suited for low to mid power electronic applications.

The housing is made from thermoplastic material with UL 94V-0 rating, offering excellent temperature resistance and mechanical strength, capable of withstanding IR reflow soldering temperatures up to 265°C. Brass contacts plated with tin ensure strong electrical conductivity and corrosion resistance. The positive latching mechanism secures connections, preventing accidental disconnections in demanding environments.

This connector uses a wire-to-board system and surface mount technology with solder tabs to firmly attach to PCBs, enhancing durability and electrical performance. The fully shrouded design provides contact isolation to minimize arcing, thus increasing the reliability of the electronic system.

Typical applications include military commercial off-the-shelf assemblies, solar power systems, consumer appliances such as dryers and refrigerators, data communications equipment like routers and servers, medical devices, telecommunications, and gaming terminals.
