This product specification describes the features and characteristics of the MINI-FIT SR series products, including product name, model, size, material, plating and marking
This specification covers the 10.00 mm centerline tin‑ and gold‑plated Mini‑Fit SR connector series, including single‑ and dual‑row versions for wire‑to‑wire and wire‑to‑PCB applications. It defines part numbers, dimensions, materials, and markings for a variety of terminal and header configurations.
Key performance data include voltage ratings of 250 V AC (IEC) and 600 V AC (UL/CSA), current ratings up to 23 A for 12 AWG conductors, operating temperature range from –40 °C to +105 °C, contact resistance limits of 1.6 mΩ (tin) or 1.0 mΩ (gold), and mechanical insertion/withdrawal forces. Environmental tests address thermal shock, humidity, vibration, and solvent resistance.
| Voltage rating (IEC) | 250 V AC (RMS) / DC |
|---|---|
| Voltage rating (UL/CSA) | 600 V AC (RMS) / DC |
| Maximum current (12 AWG, CSA) | 23 A |
| Operating temperature range | -40 °C to +105 °C |
The connectors are rated for 250 V AC (RMS) / DC per IEC 950 and 600 V AC (RMS) / DC per UL/CSA.
The connectors can operate from –40 °C up to +105 °C.
A 12 AWG wire is rated for a maximum of 23 A (CSA rating).
