Product Description
Molex 43045-2025 Micro-Fit 3.0 Series PCB Header is a high-performance wire-to-board connector designed for compact power distribution applications. Featuring a 3 mm pitch and 20 male contacts arranged in two rows, this straight through hole header provides robust electrical connections with a current rating of 5A and voltage rating of 250V. Its housing is made from high temperature UL 94V-0 liquid crystal polymer thermoplastic material, capable of withstanding temperatures up to 265°C during soldering processes.
The connector includes gold plated brass contacts to ensure excellent corrosion resistance and reliable conductivity. Positive latching via a locking ramp secures the connection against accidental disconnections in industrial and commercial environments. Metal press-fit retention clips incorporated in the design provide strong PCB retention, while the through hole mounting is SMT compatible reducing manufacturing complexity.
Operating temperature ranges from -40°C to 125°C, supporting a wide variety of applications including military COTS, solar power systems, consumer appliances like dryers and refrigerators, data communications including routers and servers, medical devices, telecommunications, and gaming terminals.
Compact power connector system with small footprint and high current capability. High temperature housings suitable for IR reflow soldering processes. Fully isolated dual beam terminals to reduce electrical arcing. Positive retention clips ensure secure mounting on PCB during operations.
Shrouded connector protects contacts and enhances mating reliability. Supports diverse industrial, laboratory, and commercial applications.
This Molex Micro-Fit 3.0 Series header offers a reliable, efficient, and durable connection solution in demanding electronic and power distribution environments. It is suitable for OEMs requiring compact, mid-range power connectors compliant with industrial standards.
