Mini-Fit Sr.™ Power Connectors
A Compact 10.00mm high-power connector system available in silver or gold, capable of handling up to 50.0A. Strong economic, ethical and environmental considerations drive electronic industries to replace gold Au with alternative plating material on connectors. Although noble metals such as palladium Pd, iridium Ir, platinum Pt provide good corrosion-resistance, these are not practical for use by virtue of availability and cost reasons. Silver Ag – a noble metal with corrosion resistance qualities along with sound conductive and mechanical properties – is accepted by industry standards as a less costly and viable plating-alternative to gold Au.
Applications which use tin Sn as plating metal face fretting corrosion issues. Customers that use gold Au as plating alternative find the solution too cost-prohibitive. ’s silver-plating not only addressed cost issues associated with gold Au as a plating material but eliminated fretting corrosion issues common with Tin-plated systems. Molex’s offering of silver-plated parts provides maximum investment protection to customer applications in both short and long term.
