Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the contact resistance of this connector? **A**: The contact resistance is specified as ≤0.5 mΩ, measured according to IEC 60512-2. This value is a reference; actual performance may vary by model and application, so verify with the manufacturer. ### Q: What battery tab thicknesses does it support? **A**: The connector supports tab thicknesses from 0.1 to 0.5 mm. Ensure your battery tabs fall within this range for proper fit and reliable connection. ### Q: What is the operating temperature range? **A**: The listed operating-temperature range is -40°C to 85°C. Confirm the exact range and qualification evidence for the specific model and application with the manufacturer. ### Q: What standards apply to this connector? **A**: Listed references include IEC 60512-2, IEC 60512-3, IEC 60512-3-1, IEC 60512-9-1, IEC 60664-1, and IEC 60512-4-1. IEC 60068-2-14 concerns specified temperature-change tests, not the connector operating-temperature range. References do not prove compliance of a specific product. ## 6.
