Micro-Fit 3.0 2×4 Pin Header Connector, 3.0mm Pitch Vertical PCB Power & Signal Connector for IDC tyco amphenol plug Socket Wire Automotive & Server

This Micro-Fit 3.0 2×4 pin header connector provides high-density, high-current power and signal transmission in a compact PCB footprint.
Heavy-duty copper-alloy square pins with 50 μ" Ni and 100 μ" Sn plating deliver low contact resistance, excellent solderability and long-term corrosion resistance. With up to 12.5 A per circuit at 250 V AC/DC, the connector is ideal for both low-voltage power rails and mixed signal lines on compact boards.

The vertical through-hole design with locating peg ensures secure PCB retention and stable performance under vibration and cable stress.
Glass-fiber-reinforced LCP housings rated UL94 V-0 and halogen-free withstand lead-free soldering temperatures and harsh operating environments from −40 °C to +105 °C. The 3.0 mm pitch matches common Micro-Fit / power header footprints and can be paired with IDC, crimp or over-molded wire harnesses for flexible system integration.

This connector can be used as an alternative to Micro-Fit-style solutions from major brands (e.g. Tyco, Amphenol) in many PCB layouts, RJ45 interface boards or IDC harness backplanes, without changing the overall application concept.

⚠️ Notes

• Ensure Correct Pin Alignment: Check orientation and positioning before mating to avoid mis-insertion, bent pins, or PCB pad damage.
• Do Not Exceed Electrical Ratings: Follow the specified current and voltage limits to prevent overheating or contact failure.
• Proper Insertion and Extraction Force: Avoid excessive force during mating/unmating to prevent deformation, cracked solder joints, or pin damage.
• Keep Contact Surfaces Clean: Ensure terminals remain free from dust, oil, oxidation, or contaminants that reduce conductivity.
• Follow Recommended Soldering Conditions: Use appropriate soldering temperature profiles according to plastic materials such as LCP, PA6T, PA66, or PBT.
• Verify PCB Hole Tolerance: Incorrect hole size may cause inadequate solder filling or mechanical instability.
• Avoid Mechanical Stress After Assembly: Do not apply lateral pressure or bending forces, especially for SMT pin headers.
• Maintain Proper Storage Conditions: Store in a dry, dust-free environment to prevent terminal oxidation; use anti-static packaging if required.
• Confirm Compatibility with Female Header: Ensure matching pitch, pin count, height, and contact design to avoid mating failure.
• Choose Correct Plating Specification: Select proper plating (gold, tin, nickel) based on your application’s durability, corrosion resistance, and signal reliability needs.
