Product Description
Molex 43045-0421 Micro-Fit 3.0 Series Right Angle Through Hole PCB Header features a 3 mm pitch dual-row design with 4 male contacts, optimized for power distribution in compact electronic assemblies.
The housing is constructed from high temperature UL 94V-0 liquid crystal polymer thermoplastic material, providing excellent resistance to heat during IR reflow soldering up to 265°C. This connector maintains reliability and mechanical strength required for industrial, telecommunications, and consumer electronics applications.
The connector system is wire-to-board, with a right angle orientation and through-hole mount type. The contacts are brass metal with tin plating for robust electrical performance and corrosion resistance. Positive latching with locking ramps is included to prevent accidental disconnection, ensuring secure connections in demanding environments.
Designed for currents up to 5 amperes and voltage rating at 250 V, this Micro-Fit 3.0 header integrates press-fit metal retention clips for stable PCB attachment and SMT compatibility, reducing manufacturing costs and enhancing assembly efficiency.
Operating temperatures range from -40°C to 105°C, making it suitable for harsh industrial conditions. Fully isolated dual beam terminals minimize arcing, enhancing electrical safety and longevity.
These headers are widely used in military commercial off-the-shelf (COTS) products, solar power systems, consumer appliances such as dryers and refrigerators, data communication equipment including routers and servers, medical devices, telecommunications gear, and gaming terminals.
High current capacity in a small footprint. Heat resistant housing suitable for IR reflow soldering. Right angle, through-hole mount design with secure positive latching. Brass contacts with tin plating for durability. Dual beam fully isolated terminals reduce arcing.
