Frequently Asked Questions
How many positions does the Molex 39-01-3048 connector offer, and what contact series is it compatible with?
The Molex 39-01-3048 is a 4-position Mini-Fit Jr. receptacle compatible with Molex contacts 39-00-0077 and 39-00-0038. The 4-position arrangement with polarized housing allows correct mating in one orientation only, reducing risk of mis-wiring in high-current power applications such as PC power supplies and industrial motor drives.
What are the body dimensions of the 39-01-3048, and how do they fit standard PCB or cable harness layouts?
The 39-01-3048 has a body measuring 0.457 inch in length, 0.457 inch in breadth, and 0.772 inch in depth. These compact Mini-Fit Jr. dimensions are standard across many PC and server power supply cable assemblies, making the connector a drop-in fit for 4-pin ATX CPU power connectors, drive power harnesses, and industrial wiring looms designed to the Mini-Fit Jr. footprint.
Which high-current power applications are best served by using the Molex 39-01-3048 instead of a lower-current connector family?
The Mini-Fit Jr. series, including the 39-01-3048, is rated for up to 9 A per contact, making it appropriate for CPU auxiliary power, GPU power, and industrial motor controller wiring where 4-position connectors must carry 20 A to 36 A total without excessive voltage drop or thermal rise. Lower-current alternatives such as Micro-Fit 3.0 are rated for only 5 A per contact and would overheat under the same load, making the Mini-Fit Jr. the correct choice for power delivery in these demanding scenarios.
