Molex Mini-Fit Jr Series PCB Header 10 Contact 4.2 mm Pitch 2 Row Shrouded Through Hole 600V 7A 39-28-1103

Molex 39-28-1103 Mini-Fit Jr Series PCB Header is a high-quality, robust connector designed for electronic components requiring secure and reliable wire-to-board connections. This connector features 10 male contacts arranged in 2 straight rows with a 4.2 mm pitch, providing a compact yet efficient interface for power and signal transmission. Rated at 7A current per contact and 600V, it supports demanding electrical loads reliably across an operating temperature range of -40°C to 105°C.

Constructed with brass contact material and tin plating, the header ensures optimal electrical conductivity and corrosion resistance. The shrouded nylon housing provides excellent insulation and mechanical protection, reducing risks of arcing and contact damage during handling. Its positive locking mechanism offers vibration resistance and an audible click feedback to guarantee proper and secure mating with mating housing and wire terminals from the Mini-Fit Jr series.

This PCB header is designed for through-hole mounting with a solder termination tail length of 3.5 mm, assuring robust mechanical and electrical connection on circuit boards. The polarized keying features prevent misalignment and assure correct orientation during assembly, minimizing errors in complex electronic assemblies.

Applications span a range of industries including security systems, data centers, consumer robotics, and other high-reliability electronic systems requiring compact, strong, and safe power connectors.

Molex Mini-Fit Jr connectors offer high current capacity up to 9A per circuit with fully isolated terminals, scoop-proof design to protect pins from damage, and are compliant with industrial quality standards. This product is manufactured in Japan, ensuring premium manufacturing quality and consistent performance.
