Molex Micro-Fit 3.0 Series Straight Surface PCB Header 2 Contacts 3mm Pitch 2 Row Shrouded 43045-0219

Molex 43045-0219 Micro-Fit 3.0 Series Straight Surface PCB Header is a dual-row, 2-contact, 3 mm pitch wire-to-board SMT header designed to deliver reliable power distribution in compact electronic assemblies.

The connector utilizes a thermoplastic housing rated UL 94V-0 and liquid crystal polymer materials that withstand soldering processes up to 265°C during infrared reflow, ensuring robust durability in PCB manufacturing.

Brass contacts plated with gold provide excellent conductivity and resistance to oxidation, suitable for carrying currents up to 5 amperes while maintaining a small footprint with a 3 mm pitch and 2 rows.

Positive latching with a locking ramp offers secure mating and prevents accidental disconnections in industrial and commercial environments. The connector’s solder tabs afford a stable mechanical mount on PCB surfaces, enhancing long-term reliability and resistance to vibration.

Supports 5 amp current capacity in a compact 3 mm pitch dual row format. High-temperature housing suitable for IR reflow soldering at temperatures up to 265°C. Gold-plated brass contacts optimize electrical performance and durability.

Includes positive latching locking ramp for secure connections. Solder tabs ensure secure mounting on PCB surface. Fully isolated dual beam terminals reduce arcing risks. Operating temperature range from -40°C to 125°C. Ideal for military, solar power, consumer products, data communications, medical, telecom, and gaming applications.

This PCB header is widely employed in industrial, laboratory, telecommunications, manufacturing, and consumer electronics sectors, providing a compact, high-quality connection interface.
