This Micro-Fit 3.0 2×12 pin header connector is optimized for high-density, high-current power and signal transmission on compact PCBs.
The 3.0 mm pitch, dual-row 24-pin layout provides abundant circuits for mixed power and control signals while keeping the footprint small. Square copper-alloy pins and stamped solder tabs are finished with 50 μ" nickel and 100 μ" tin plating, delivering low contact resistance, strong solderability and excellent corrosion resistance even after 24-hour salt-spray testing.
With a rated current of 12.5 A per circuit at 250 V AC/DC, this connector is ideal for low-voltage power rails and robust signal links.
The vertical through-hole structure with locating peg ensures accurate PCB positioning and strong mechanical anchoring, maintaining stability under vibration, cable pull and repeated mating cycles. Glass-fiber-reinforced LCP housings rated UL94 V-0 and halogen-free withstand lead-free soldering profiles and an operating temperature range of −40 °C to +105 °C, making the connector suitable for harsh industrial and automotive environments.

⚠️ 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.
