Micro-Fit 3.0 tyco Pin Header 3.0mm Pitch 2×6 Vertical PCB Power & Signal Connector with Peg, Tin-Plated Terminals for IDC Wire Harness, Automotive & Server

This Micro-Fit 3.0 2×6 pin header connector is designed for compact, high-current power and signal transmission on densely populated PCBs.
Square copper-alloy pins with 50 μ" nickel and 100 μ" tin plating ensure low contact resistance, strong solderability and excellent corrosion resistance after salt-spray testing. With up to 12.5 A per circuit at 250 V AC/DC, it easily supports low-voltage power rails and mixed signal lines for modern electronics.

The vertical through-hole design with positioning peg provides secure PCB anchoring and stable performance under vibration, cable pull and repeated mating.
Glass-fiber-reinforced LCP housings rated UL94 V-0 and halogen-free withstand lead-free soldering profiles and harsh operating temperatures from −40 °C to +105 °C. The 3.0 mm pitch is compatible with many Micro-Fit-style footprints, enabling easy replacement or second-source options in existing Tyco / Amphenol layouts.

Combined with IDC or crimped wire harnesses, this connector offers a flexible, customized interconnection solution for power distribution, control signals and data links.

⚠️ 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.
