Mini-Fit Sr. Power Connectors

Molex's Mini-Fit Sr. compact 10 mm high-power connector system is available in silver (Ag) or gold (Au) and is capable of handling up to 50 A. This series offers a range of 8 AWG to 16 AWG with an offering of two to fourteen circuits.

Strong economic, ethical, and environmental considerations drive electronic industries to replace gold with alternative plating material on connectors. Although noble metals such as palladium (Pd), iridium (Ir), and platinum (Pt) provide good corrosion resistance, these are not practical for use due to availability and cost reasons. Silver, a noble metal with corrosion resistance qualities along with sound conductive and mechanical properties, is accepted by industry standards as a viable and less costly plating alternative to gold.

Applications that use tin (Sn) as plating metal face fretting corrosion issues. Customers that use gold as the plating alternative find the solution too cost-prohibitive. Molex’s silver plating not only addresses cost issues associated with gold as a plating material but eliminates fretting corrosion issues common with tin-plated systems. Molex’s offering of silver-plated parts provides maximum investment protection to both short- and long-term customer applications.

Features

• Silver-plated contacts offer significant cost savings over gold-plated systems and mitigate fretting corrosion, eliminating the need to manually lubricate tin-plated versions
• Polarized housing design prevents mismating
• Terminal position assurance (TPA) retainer is required on housings to prevent terminal back-out
• High amperage (50 A) isolated contacts support high-power servers, telecommunication, and industrial equipment requirements
• Dual-beam (female) terminal design gives four points of contact and ensures superb contact reliability
