Molex

Power connectors rarely enjoy the spotlight, but Molex's Fit Family earns it. This scalable ecosystem of wire-to-board and wire-to-wire connectors progresses through five pitch tiers — Nano-Fit at 2.50mm (8A), Micro-Fit/Micro-Fit+ at 3.00mm (10.5A/13A), Ultra-Fit at 3.50mm (14A), Mini-Fit at 4.20mm (13A), and Mega-Fit at 5.70mm (30A). Every member shares the same design DNA: polarization, positive locking, fully isolated contacts, and high-temperature LCP headers capable of withstanding 265°C IR reflow. ICSourceDirect carries the complete family in depth — including Mini-Fit BMI blind-mate variants and Mini-Fit TPA with terminal position assurance, both notoriously tight on factory lead times.
