Product Description
Molex 39-30-3045 Mini-Fit Jr Series Right Angle Through Hole PCB Header is a high-quality, shrouded PCB connector designed for power applications requiring robust current handling and secure connections. Featuring a 4.2 mm pitch and 4 contact points arranged in a single row, this connector is specifically engineered for wire-to-board interfacing. The nylon housing ensures excellent insulation with durability under a wide operating temperature range from -40°C to 105°C.
The brass male contacts with tin plating guarantee reliable conductivity and corrosion resistance. The shrouded design protects terminals against debris, arcing, and physical damage, while scoop-proof housings prevent bent pins during harsh mating angles. The connector includes features such as polarization and keying to prevent misalignment or incorrect mating with receptacles, as well as a positive locking mechanism that provides tactile and audible feedback upon proper connection.
