Product Description
Molex 43045-0227 Micro-Fit 3.0 Series Straight Through Hole PCB Header is a dual row connector with 2 contacts and a 3 mm pitch, designed to provide a secure and reliable wire-to-board connection.
It supports a maximum current of 5A and voltage rating of 250V, making it suitable for low to mid power distribution applications. The header features a shrouded housing made from high-temperature UL 94V-0 Liquid Crystal Polymer which withstands up to 265°C during IR reflow soldering, ensuring durability and performance in demanding industrial environments.
The brass male contacts with tin plating are fully isolated within the housing to reduce arcing and ensure consistent connectivity. PCB polarizing pegs aid in alignment and positioning on circuit boards, while positive latching provides secure mating to prevent accidental disconnection during operation or vibration.
This through hole mount type is SMT compatible, reducing processing requirements and costs. The product is ideal for use in military commercial off-the-shelf (COTS) equipment, solar power systems, consumer appliances such as dryers and refrigerators, data communications infrastructure, medical devices, telecommunications hardware, and gaming terminals.
High current carrying capacity of 5A in a small footprint. High temperature resistant housing suitable for IR reflow soldering. Through hole mounting with SMT compatibility reduces assembly complexity. Positive latching mechanism ensures secure connection.
Fully isolated dual beam terminals provide reliable electrical performance. PCB polarizing pegs facilitate proper positioning and alignment. Kinked solder legs on select part numbers enhance PCB retention. Durable brass contacts with tin plating for corrosion resistance.
This Molex Micro-Fit 3.0 Series PCB header connector is an excellent choice for a broad range of industrial, commercial, and electronic applications requiring reliable, compact power connectors.
