This Micro-Fit 3.0 straight pin header connector delivers
high-current performance and reliable PCB interconnection for power
and signal transmission.
It features a 2×2 pin dual-row design, a 3.00 mm pitch, and through-hole mounting, making it suitable for high-density boards and stable power
delivery.
The terminals are made from Copper Alloy C1100 with 50μ” nickel + 100μ” tin plating, providing low contact resistance, excellent conductivity, and
corrosion protection.
The housing uses LCP E130I UL94-V0, offering heat resistance and flame-retardant performance for
industrial and automotive applications.
With a rated current of up to 12.5A per pin, strong retention force, and reliable electrical characteristics,
this connector is ideal for demanding power-supply modules and
compact PCB assemblies.

⚠️ 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.
