Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header, 4 Contacts, 3 mm Pitch, 2 Row, Shrouded 43045-0425

Molex 43045-0425 Micro-Fit 3.0 Series Straight Through Hole PCB Header offers a compact dual row design with 3 mm pitch and 4 male contacts tailored for efficient wire-to-board power connections up to 5A current rating. The connector features a high temperature thermoplastic housing that withstands up to 265°C during IR reflow soldering, enabling robust assembly compatibility.

This shrouded PCB header is designed with a secure positive latching system using a locking ramp to prevent accidental disconnections. Its brass contacts with gold plating ensure superior electrical conductivity and corrosion resistance, enhancing long-term reliability. With through hole mounting and integrated metal press-fit retention clips, it ensures strong mechanical fixation to PCB boards while maintaining SMT process compatibility to reduce assembly costs.

Operating reliably across a broad temperature range from -40°C to 125°C, this connector is ideal for demanding industrial and commercial applications. The fully isolated dual beam terminals reduce arcing risks and improve electrical safety. Applications include military commercial off-the-shelf (COTS) systems, solar power equipment, household appliances such as dryers and refrigerators, data communications hardware like routers and servers, medical devices, telecommunications infrastructure, and gaming terminals.

High current carrying capacity in a compact footprint for efficient power distribution. High temperature UL 94V-0 thermoplastic housing for durable IR reflow soldering. Straight orientation with dual row, 3 mm pitch for compact PCB layout.

Gold plated brass contacts provide excellent conductivity and corrosion resistance. Positive latching mechanism ensures secure mating connections. Metal press-fit retention clips provide reliable mechanical PCB retention.

Fully isolated terminals minimize electrical arcing for improved safety. Wide operating temperature range from -40°C to 125°C supports diverse environments. Shrouded housing enhances contact protection and insulation.

This Molex Micro-Fit 3.0 Series PCB header is engineered to meet rigorous standards for power connectors used in industrial, commercial, and high-reliability sectors. Its combination of robust design, manufacturing flexibility, and reliable electrical performance makes it a preferred choice for engineers and designers.
