Product Description
Molex 39-28-1183 Mini-Fit Jr Series PCB Header is a shrouded, straight through-hole connector with 18 male contacts arranged in 2 rows at 4.2 mm pitch. Rated at 600V and 6A per circuit, it is constructed with a nylon housing and brass contacts plated with tin. The connector offers fully isolated terminals to protect against debris and arcing, and the scoop-proof housing prevents damage to pin terminals during mating.
These PCB headers feature polarization and keying mechanisms that prevent misalignment and mismating with the receptacle, ensuring reliability in demanding industrial and commercial environments. The positive locking mechanism provides a secure connection with an audible click confirming full mating. The tail pin length is 3.5mm, enabling robust solder termination through the PCB.
Designed to withstand operating temperatures from -40°C to 105°C, this PCB header is suitable for consumer white goods, office equipment, industrial automation, network servers, routers, and switches. Its wire-to-board connector system and through-hole mount type provide design flexibility and durability.
Versions with snap-in retention pegs and mounting flanges are also available for enhanced PCB stability. The Mini-Fit Junior power connectors are ideally used in high current, high density wire-to-wire and wire-to-board interconnections that demand safe and reliable power delivery.
