Mini-Fit Jr. Connectors

Molex Mini-Fit Jr. Connectors are ideal for higher-current / higher-density applications that require design flexibility for wire-to-wire and wire-to-board configurations. Molex Mini-Fit Jr. connectors are made for power applications up to 9.0A per circuit. The connectors feature fully isolated terminals, positive housing locks, low-engagement forces, and polarized housings. They are UL recognized, CSA approved, and TUV licensed. All components are lead free and RoHS compliant. Molex Mini-Fit Jr. Connectors are available in a single row or dual row, 2 to 24 circuit options, and multiple plating and material selections.
