Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 5 Contacts 3 mm Pitch 1 Row Shrouded 43650-0517

Molex 43650-0517 Micro-Fit 3.0 Series straight through hole PCB header is a reliable electronic connector designed for efficient low to mid power distribution applications. It features a single row of 5 male contacts spaced at 3 mm pitch within a shrouded, thermoplastic housing constructed from high-temperature UL 94V-0 Liquid Crystal Polymer. This enables the connector to withstand up to 265°C during IR reflow soldering processes.

The connector system offers a compact footprint with a high current capacity of 5 amperes, making it suitable for military COTS, solar power setups, consumer appliances such as dryers and fridges, data communications equipment including routers and servers, telecommunications, medical devices, and gaming terminals.

This through-hole PCB header benefits from positive latching with a locking ramp mechanism that ensures a secure connection and prevents accidental disconnections. The incorporation of PCB polarising pegs aids in precise alignment and positioning on the circuit board. Additionally, select part numbers provide kinked solder legs for enhanced mechanical retention on the PCB.

The brass contacts plated with gold enhance electrical reliability and durability. The connector supports a voltage of 250 volts and operates reliably within a temperature range from -40°C to 105°C. It is designed with fully isolated dual beam terminals to reduce electrical arcing and improve performance. Through-hole mounting versions also support surface mount technology (SMT) processes, which streamline production and reduce manufacturing cost.

This Molex Micro-Fit 3.0 Series PCB header is widely used in industrial, telecommunications, medical, consumer electronics, and other commercial applications where dependable and compact power connector solutions are essential.
