Molex Mini-Fit Jr Series Straight Through Hole PCB Header, 14 Contacts, 4.2 mm Pitch, 2 Row, Shrouded 39-31-0140

Molex 39-31-0140 Mini-Fit Jr Series Straight Through Hole PCB Header is a high-quality power connector designed for wire-to-board applications requiring high current capacity and reliability. This PCB header features 14 male contacts arranged in 2 rows with a 4.2 mm pitch. The shrouded housing made of durable nylon provides mechanical protection and ensures correct polarization and keying to prevent misalignment and mismating with mating receptacles.

The brass contacts with tin plating offer excellent electrical conductivity and corrosion resistance. The scoop-proof design of the housing protects the contacts from damage during mating, even when connected at severe angles. The connector also includes a positive locking mechanism that secures the connection with an audible click to indicate full mating, preventing accidental disconnects caused by vibration or shock.

Terminated using solder tails with a 3.5 mm length, this through-hole mounted header ensures a secure and robust connection to printed circuit boards (PCBs). It is rated for currents up to 9A per circuit and voltages up to 600V, making it suitable for high current electronic, industrial, and power applications. Operating temperature ranges from -40°C to 105°C for versatile environments.

The Mini-Fit Jr series PCB Headers are widely used in consumer electronics, industrial automation, office equipment, network servers, routers, and telecommunications equipment where reliable power connections are essential. Versions with PCB mounting pegs and flange options are available to enhance mechanical stability.
