Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact plating thickness requirement of ≥0.75 µm gold against application needs. Confirm that the target wire diameter falls within the 0.65 mm to 0.85 mm range for proper spring contact engagement. Ensure the operating environment does not exceed the 15 g vibration resistance limit. Check compatibility with the nominal current rating of 3 A for the intended circuit load.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when high-precision connections are required for wires within the 0.65–0.85 mm diameter range. The internal spring contact mechanism offers advantages over standard press-fit designs for these specific wire sizes. Consider the low capacitance and resistance values if signal integrity is critical. The gold plating is suitable for applications demanding long-term reliability and resistance to environmental degradation.
