Molex Micro-Fit 3.0 Series Straight Through Hole Shrouded PCB Header 4 Contacts 3 mm Pitch 1 Row 43650-0427

Molex 43650-0427 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a high-quality, low to mid-power wire-to-board connector designed for reliable electrical connections in compact spaces. This model features 4 shrouded male contacts arranged in a single row with a 3 mm pitch, optimized for tight spacing in PCB applications.

The connector housing is made from thermoplastic material rated for high temperatures, capable of withstanding up to 265°C during IR reflow soldering, facilitating modern assembly processes. It includes a positive latching mechanism via a locking ramp that ensures secure and stable mating, preventing accidental disconnections in demanding environments.

The contacts are crafted from brass and plated with tin to ensure excellent conductivity and corrosion resistance. With a current capacity of 5 amps and voltage rating up to 250 volts, this connector supports efficient power delivery for various industrial and commercial electronics.

Additional design features include PCB polarising pegs that aid in precise positioning and alignment during PCB assembly, enhancing manufacturing accuracy. The through hole mounting style and straight orientation of the contacts make it compatible with standard PCB layouts. The connector is also glow wire compliant and designed to meet demanding operating temperature ranges from -40˚C to 105˚C.

The Molex Micro-Fit 3.0 series connectors are widely used across numerous fields such as military commercial off-the-shelf components, solar power systems, household appliances like dryers and refrigerators, telecommunications, data communications, gaming terminals, and medical equipment.
