Molex Mini-Fit Jr Series Straight Through Hole PCB Header 4 Contact 4.2 mm Pitch 2 Row Shrouded 39-29-0043

The Molex Mini-Fit Jr Series model 39-29-0043 is a high-quality straight through hole PCB header designed for power connector applications requiring robust current handling and secure connections. With 4 contacts arranged in 2 rows and a 4.2 mm pitch, this component is ideal for high current wire-to-board interconnections in industrial and commercial electronic assemblies.

Its nylon housing material is scoop-proof to prevent pin terminal damage and integrates polarization and keying features to eliminate misalignment or mismating with receptacles. The male brass contacts are plated with gold, enhancing conductivity and corrosion resistance, while fully isolated terminals protect against arcing and debris.

The connector supports a maximum current of 9 amperes per circuit and withstands voltages up to 600 volts, operating reliably within -40°C to 105°C temperature range. This makes it suitable for applications such as consumer white goods, office machinery, industrial automation, networking equipment, rack-mount servers, and telecommunications devices.

The mounting type is through-hole, with termination by soldering, ensuring firm mechanical and electrical attachment to printed circuit boards. Additionally, the connector's positive locking mechanism with an audible click assures a secure mating connection, resistant to shock and vibration in harsh environments.

This Mini-Fit Junior PCB header can be optionally supplied with PCB retention pegs and mounting flanges to enhance stability on the board. Its design complies with typical industrial quality standards, although it does not carry specific certifications.
