Molex Micro-Fit 3.0 Series Right Angle Through Hole PCB Header, 6 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-0621

Molex 43045-0621 Micro-Fit 3.0 Series Right Angle Through Hole PCB Header is a high-performance connector designed for reliable wire-to-board connections with a 3 mm pitch and two rows of six male contacts. The shrouded housing is manufactured from high temperature UL 94V-0 Liquid Crystal Polymer that can endure up to 265°C during IR reflow soldering, enabling strong thermal resistance for demanding PCB assembly processes.

This connector supports a current rating of 5A and voltage rating of 250V, making it ideal for low to mid power applications in sectors such as telecommunications, medical devices, consumer appliances, data communications equipment, and solar power systems. Its right angle orientation facilitates space-saving PCB layouts, while dual beam terminals fully isolate contacts to reduce potential arcing and enhance electrical performance.

Designed with positive latching via a locking ramp on the housing, it ensures secure mating and prevents accidental disconnections. The inclusion of metal press-fit retention clips improves mechanical stability by securing the header firmly to the PCB.

The brass contacts with tin plating balance cost and conductivity, providing dependable electrical paths. The operating temperature range from -40°C to 125°C allows usage in a variety of environments, including industrial and commercial applications.

Right angle orientation and through hole mount provide robust PCB integration. High temperature thermoplastic housing supports IR reflow soldering processes. Rated for 5A current and 250V voltage for versatile power applications.

Positive latching mechanism prevents accidental connector disengagement. Metal press-fit retention clips enhance PCB mechanical stability. Dual row, 6 contact configuration with 3 mm pitch for compact design. Contact plating with tin ensures reliable conductivity and corrosion resistance.

This connector series is suited for use in military COTS, consumer electronics such as dryers and refrigerators, data communication hardware including routers and servers, medical and gaming terminal equipment, and solar power installations. Molex’s Micro-Fit 3.0 series delivers a compact yet high current capacity solution optimized for industrial, commercial, and telecommunications needs.
