Product Description
Molex 43045-2013 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a high-performance, compact PCB connector featuring 20 male contacts arranged in 2 rows with a precise 3 mm pitch. This dual row PCB header is shrouded and designed for wire-to-board connections, providing reliable and durable electrical contacts in industrial and commercial electronics.
The housing material is a high temperature thermoplastic capable of withstanding operating temperatures from -40°C up to 125°C, allowing robust performance even in challenging environments. The gold-plated brass contacts ensure low contact resistance and excellent corrosion resistance. Its mounting type is through hole, compatible with wave soldering and IR reflow processes.
With a rated current of 5A and voltage of 250V, the Micro-Fit 3.0 offers one of the highest current carrying capabilities in its compact footprint. The connector incorporates positive latching via a locking ramp to secure mating connections and avoid accidental disconnections, critical for reliable power distribution in electronics.
Additional features include fully isolated dual beam terminals to reduce arcing and prolong connector life, and PCB polarising pegs that aid precise positioning and mechanical stability on the PCB board. Some variants include kinked solder legs for enhanced retention in assembly.
