Product Description
Molex 43045-1419 Micro-Fit 3.0 Series Straight Surface PCB Header is engineered for wire-to-board applications requiring compact size and high current capacity. It features 14 male contacts spaced by a 3 mm pitch arranged in two straight rows with a shrouded housing ensuring protection and secure mating.
The housing is manufactured from high temperature UL 94V-0 liquid crystal polymer, durable for IR reflow soldering processes up to 265°C. This header supports up to 5A of current, offering one of the highest current densities available in small footprint connectors.
Brass contacts are plated with gold to deliver excellent electrical conductivity and prevent corrosion, while fully isolated dual beam terminals provide reliable contact integrity and reduce arcing. The positive latching mechanism via locking ramp prevents accidental disconnections in demanding environments.
Solder tabs included in the design ensure robust attachment to surface mount PCBs, improving mechanical stability especially in vibration-sensitive or industrial use cases.
This connector series is widely applied in military commercial off-the-shelf (COTS) systems, solar energy installations, consumer electrical products such as dryers and refrigerators, medical devices, data communications equipment like routers and servers, telecommunications units, and gaming terminals.
