Molex Micro-Fit 3.0 Series Straight Surface PCB Header 6 Contact, 3 mm Pitch, 1 Row, Shrouded 43650-0621

Molex 43650-0621 Micro-Fit 3.0 Series Straight Surface PCB Header is a compact power connector system designed for low to mid-range power distribution applications. This 6-contact, 3 mm pitch, 1-row shrouded connector supports a current rating of up to 5A and voltage rating of 250V, making it suitable for a variety of electronic assemblies.

The housing is constructed from high-temperature UL 94V-0 liquid crystal polymer thermoplastic, capable of withstanding temperatures up to 265°C during infrared reflow soldering, ensuring reliability and durability during assembly processes. It features a positive latching mechanism with a locking ramp on the housing to secure mating and prevent accidental unplugging, critical for high-reliability applications.

This surface mount compatible connector incorporates solderable metal press-fit retention clips to secure the header to the PCB, enhancing mechanical stability. The contacts are brass with tin plating, fully isolated to minimize arcing and maintain electrical integrity. The connector’s design supports straight orientation and wire-to-board connection systems.

Operating reliably in temperature ranges from -40°C to 125°C, these headers are ideal for military commercial off-the-shelf (COTS) equipment, solar power systems, telecommunications, consumer electronics, data communications, medical devices, and gaming terminals. The through-hole version is also surface mount technology compatible, reducing process costs and offering versatility.
