Product Description
Molex 39-28-8220 Mini-Fit Jr Series Straight Through Hole PCB Header features a 22-contact arrangement in 2 rows with a 4.2 mm pitch designed for high current wire-to-board applications. The connector's nylon housing ensures robustness and incorporates scoop-proof design to protect contact terminals during mating. Fully isolated terminals prevent debris intrusion, arcing, and damage from mishandling, making it suitable for demanding industrial environments.
The connector supports up to 6A current per circuit with a voltage rating of 600V, making it ideal for consumer white goods, industrial automation, networking equipment, and computing devices. Its polarization and keying design ensure proper alignment to prevent mismating, while a positive locking mechanism with an audible click confirms secure connections, even under vibration or shock.
This male contact connector uses brass contacts plated with tin to reduce corrosion and improve conductivity. It operates reliably across a temperature range of -40°C to 105°C and terminates by soldering into printed circuit boards through a through-hole mount. Versions are also available with PCB retention pegs and mounting flanges for enhanced mechanical stability.
Molex Mini-Fit Jr connectors are widely used in industrial, commercial, telecommunications, and office electronics applications requiring compact, high-density, and high-current power interconnections.
Supports up to 6A current per contact for high power circuits. Durable nylon housing material designed for harsh environments. Scoop-proof design protects pins during connector mating. Positive locking mechanism ensures secure and vibration-resistant connection.
