Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 10 Contact 3 mm Pitch 2 Row Shrouded 43045-1024

Molex 43045-1024 Micro-Fit 3.0 Series straight through hole PCB header is a high-quality power connector designed for reliable wire-to-board electrical connections. It features a compact dual-row, 10-contact configuration with a 3.0 mm pitch and shrouded housing to protect contacts and prevent misalignment during mating. The straight male contacts are made of brass and plated with tin, ensuring excellent conductivity and corrosion resistance.

The connector's housing is composed of high temperature UL 94V-0 liquid crystal polymer, allowing it to withstand operating temperatures up to 125°C and endure infrared reflow soldering temperatures as high as 265°C. This makes it suitable for rigorous manufacturing processes while maintaining structural integrity. Its through hole mount type combined with metal press-fit retention clips optimizes mechanical stability on the PCB.

Designed for current ratings up to 5A and voltage tolerance of 250V, the Micro-Fit 3.0 Series provides one of the highest current capacities in its compact footprint. The dual beam fully isolated terminals reduce the risk of arcing, enhancing safety and performance in demanding applications.

The positive latching feature provides a secure connection with a locking ramp on the housing, preventing accidental disconnection in operational environments. This connector series complies with Glow Wire standards, increasing its suitability for consumer electronic devices and appliances.

Applications for this PCB header include commercial off-the-shelf military equipment, solar power systems, household consumer products such as dryers and refrigerators, data communications hardware including routers and servers, telecommunications, medical devices, and gaming terminals. Its versatility across various industrial and commercial sectors makes it a dependable choice for mid to low power distribution solutions.

This PCB header features a 3.0 mm pitch and supports up to 5A current capacity. The connector is designed with 2 rows of 10 straight male contacts. High temperature thermoplastic housing ensures durability up to 125°C operating temperature.
