Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 5 Contacts 3 mm Pitch 1 Row Shrouded 43650-0516

Molex 43650-0516 Micro-Fit 3.0 Series straight through hole PCB header is a shrouded wire-to-board connector designed for compact power distribution solutions. It incorporates 5 male contacts arranged in a single row with a 3 mm pitch. The connector supports up to 5 amperes of current, making it suitable for low to mid-range power applications in electronics manufacturing, automotive, telecommunications, and consumer products.

The housing is made of high-temperature UL 94V-0 liquid crystal polymer thermoplastic, enabling it to withstand IR reflow soldering temperatures up to 265°C. This header features a positive latching mechanism with a locking ramp on the housing to secure mating connections and prevent accidental disconnection during high-vibration applications. The gold-plated brass contacts ensure reliable conductivity and corrosion resistance.

These PCB headers use kinked solder legs providing additional retention on the PCB and are SMT compatible to reduce production costs. PCB polarizing pegs facilitate proper positioning and alignment onto the board, enhancing assembly efficiency. The design fully isolates contacts within the housing to reduce risk of arcing and improve electrical performance.

Typical applications include military COTS systems, solar power installations, household appliances such as dryers and refrigerators, data communications equipment, medical devices, telecommunications infrastructure, and gaming terminals.
