Micro-Fit 3.0 Connector System

Molex Micro-Fit 3.0 Connector System is designed to meet the needs for high contact density signal or power connectors. Micro-Fit 3.0 connectors feature a miniature 3mm (0.118") pitch, yet retain many of the features found on larger power connectors and can carry up to 8.5A of current. Molex Micro-Fit products are available in circuit sizes 2 to 24 for single- and dual-row, wire-to-board, and wire-to-wire applications such as computers, work stations, satellites, cellular phones, and a host of consumer products. Molex 46235 Micro-Fit 3.00mm Low Force Terminal offers the same reliability as the standard Micro-Fit products, but with half of the mating / unmating force for applications using large circuit sizes.
