Product Description
Molex Micro-Fit 3.0 Series PCB Header model 43650-0421 is a high-performance 4-contact wire-to-board connector with a 3 mm pitch and single row, shrouded configuration designed for surface mounting. It is engineered to provide a reliable low to mid-range power distribution solution with a current capacity of 5A.
This header features thermoplastic housing and brass contacts plated with tin, ensuring durable electrical connections. The connector incorporates positive latching via a locking ramp on the housing to provide secure mating and to prevent accidental disconnection during operation.
The housing material is a high-temperature UL94V-0 liquid crystal polymer, capable of withstanding temperatures up to 265°C during infrared reflow soldering processes, making it suitable for modern PCB manufacturing techniques. The solder termination type combined with metal press-fit retention clips ensures secure mechanical attachment to PCB surfaces, reducing process costs and enhancing reliability.
Operating temperature ranges from -40°C to 105°C, supporting applications in harsh environments. The contacts are fully isolated within the housing to minimize electrical arcing, improving safety and durability.
Typical industrial and commercial applications include military commercial off-the-shelf (COTS) solutions, solar energy systems, consumer electronics, data communication devices, medical equipment, telecommunications infrastructure, and gaming terminals.
Supports up to 5A current in compact design. High-temperature thermoplastic housing for advanced soldering. Positive latching mechanism for secure connections. Solder termination with press-fit retention for reliability.
