Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 4 Contacts, 3 mm Pitch, 1 Row, Shrouded 43650-0416

Molex 43650-0416 Micro-Fit 3.0 Series straight through hole PCB header is a high-performance connector designed for efficient and secure wire-to-board applications. This single row header features a 3 mm pitch and 4 male brass contacts, gold-plated to provide excellent electrical conductivity and resistance to corrosion. The housing is made from thermoplastic material compliant with UL 94V-0, capable of withstanding temperatures up to 265°C during IR reflow soldering processes, making it ideal for advanced PCB assembly.

The connector system includes PCB polarizing pegs to ensure correct positioning on the PCB and kinked solder legs to enhance PCB retention, providing robustness during mechanical stress. The positive latching locking ramp ensures secure mating, preventing accidental disconnection in demanding industrial environments. Rated for 5A current and 250V voltage, it delivers high power in a compact footprint suitable for commercial and industrial electronics.

With an operating temperature range from -40°C to 105°C, the Micro-Fit 3.0 header is versatile for applications including telecommunications, medical devices, data communications equipment like routers and servers, consumer products such as dryers and freezers, and solar power systems. The through-hole mount is SMT compatible, optimizing manufacturing efficiency and reducing costs.
