Product Description
Molex 43045-0425 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a compact power connector designed for wire-to-board connectivity. This 4 contact, dual row, 3 mm pitch header features a shrouded housing for secure connections in demanding electronic assemblies.
The connector housing is made from high temperature thermoplastic that withstands IR reflow soldering temperatures up to 265°C, ensuring durability during manufacturing processes. It incorporates metal press-fit retention clips for robust attachment to PCBs, compatible with SMT processes as well, reducing production costs.
With a current rating of 5A and voltage rating of 250V, this Micro-Fit 3.0 header is ideal for low to mid power distribution in industrial, telecommunications, medical, gaming, and consumer electronics sectors. The positive latching mechanism with a locking ramp prevents accidental disconnections, increasing reliability.
The brass contacts are gold plated to prevent corrosion and provide consistent electrical conductivity, fully isolated within the housing to reduce arcing. Operating temperature ranges from -40°C to 125°C ensure functionality in harsh environments.
Applications include military commercial off-the-shelf systems, solar power equipment, household appliances like dryers and refrigerators, data communication devices such as routers and servers, healthcare devices, and gaming terminals.
