Molex Mini-Fit Sr. Power Connectors

Molex Mini-Fit Sr. Power Connectors offer high electrical reliability while supporting currents up to 50A across various industrial, consumer, automotive, medical, telecommunication, and networking applications. These compact connectors feature a polarized housing to prevent mismating, silver-plated contacts for cost savings compared to gold-plated systems, and a dual-beam (female) terminal design with four contact points to ensure superb reliability. A Terminal Position Assurance (TPA) retainer also prevents terminal back-out, enhancing connection stability. The connectors support a maximum voltage of 600V with a contact resistance of 10mΩ and an insulation resistance of 1000MΩ. This combination of features makes Molex Mini-Fit Sr. power connectors the right choice for applications requiring robust, high-current connections with reliable performance.
