Molex Mini-Fit Jr 4.2mm Pre-Crimped Terminal Female single-head Cable (Without Connector), 18AWG UL1007 PVC

Molex Mini-Fit Jr. 4.2mm Female Single-Head Pre-Crimped Terminal Cable — 18AWG UL1007 PVC, 9A / 600V

The Molex Mini-Fit Jr. 4.2mm female single-head pre-crimped terminal cable is the professional-grade solution for custom high-current power harness assembly. Featuring a genuine Molex Mini-Fit Jr. female crimp terminal on one end and a bare tinned lead on the other — without a housing — this cable is designed for applications where the Mini-Fit Jr. housing is already installed on the PCB or device, and one end must be soldered directly to a PCB pad, bus bar, or screw terminal.

With an 18AWG UL1007 PVC conductor rated at 9A per contact and 600V, this cable handles the demanding current loads of ATX power supplies, industrial motor drives, server power distribution, and automotive power harnesses — far beyond the capability of standard signal-level connectors.

Key Features

• Genuine Molex Mini-Fit Jr. female crimp terminal — precision-stamped contact for reliable, low-resistance crimped connections in Mini-Fit Jr. housings (Molex 39012 / 5557 series)
• Single-head configuration — female terminal one end, bare tinned lead other end; ideal when one end is soldered to a PCB pad, bus bar, or screw terminal
• 18AWG UL1007 PVC insulation — rated 80°C, 300V, flexible and durable for power wiring applications
• 9A / 600V rating — handles high-current power lines in ATX, industrial, and automotive applications
• Pre-crimped factory assembly — consistent, reliable crimp quality; eliminates field crimping errors
• Bare tinned lead — pre-tinned for direct PCB pad soldering, screw terminal connection, or custom connector termination
• RoHS compliant — meets EU RoHS 2 directive for hazardous substance restrictions

Typical Applications

• ATX power supply harness assembly — custom 24-pin, 8-pin EPS, and PCIe power cable fabrication
• Industrial motor drive and inverter wiring — high-current power distribution harness assembly
• Server and data center power distribution — custom power harness for rack-mount equipment
• Automotive power harness assembly — battery, alternator, and high-current circuit wiring
• Custom PCB power connector population — where Mini-Fit Jr. housing is pre-installed on the PCB
• Replacement terminal cables — for repair and maintenance of existing Mini-Fit Jr. harnesses

Molex Mini-Fit Jr. Terminal Cable Configurations

• Female single-head (this product): Female terminal one end, bare lead other — use when one end is soldered to a PCB pad or screw terminal
• Female both-sided: Female terminals both ends — use when both ends insert into pre-installed Mini-Fit Jr. housings
• Male single-head: Male terminal one end, bare lead other — use for plug-side harness assembly with one soldered end
