Molex Micro-Fit 3.0 Series Straight Through Hole PCB Header 2 Contact 3 mm Pitch 2 Row Shrouded 43045-0225

Molex 43045-0225 Micro-Fit 3.0 Series Straight Through Hole PCB Header offers a compact, high-performance dual-row connector solution with 2 contacts and 3 mm pitch. This shrouded header is designed to provide a secure electrical connection in various industrial and electronic applications.

The housing is molded from high temperature UL 94V-0 Liquid Crystal Polymer, enabling it to withstand reflow soldering temperatures up to 265°C. The connector supports currents up to 5A, which is among the highest current capacities for connectors in such a small footprint.

Featuring positive latching with a locking ramp, the header ensures that connections remain safe and secure even under vibration or mechanical stress. The contacts, made of brass with gold plating, provide durability and excellent conductivity. Metal press-fit retention clips hold the connector firmly to the PCB, ensuring stable mounting and reducing assembly costs due to SMT compatibility.

This Micro-Fit 3.0 header is fully isolated within the housing to minimize arcing and electrical interference, improving signal integrity and performance. The operating temperature range from -40°C to 125°C makes it suitable for demanding environments.

Applications for this connector include military commercial off-the-shelf (COTS) products, solar power systems, consumer appliances such as dryers and refrigerators, data communications equipment including routers and servers, medical devices, telecommunications gear, and gaming terminals.

Designed for wire-to-board applications with a straight through-hole mount type. Constructed with high-temperature thermoplastic housing to withstand IR reflow soldering. Supports up to 5A current, making it suitable for low to mid power distributions.

Includes positive latching with locking ramps to prevent accidental disconnects. Contacts are brass with gold plating for reliable conductivity and corrosion resistance. Operating temperature range is from -40°C to 125°C.

The connector features metal press-fit retention clips for secure PCB mounting. Fully isolated contacts reduce arcing and improve electrical performance. Compact dual-row 3 mm pitch design saves PCB space. RoHS compliant and suitable for military, solar, consumer, medical, and telecommunications applications.
