The Micro-Fit 3.0 system provides a compact power and signal interconnect solution with a 3.0mm pitch, offering up to 8.5A per contact and 600V voltage rating. This 4-circuit version (2 rows x 2 columns) is designed for wire-to-board power delivery applications where space is limited. The right-angle orientation enables low-profile connections along the PCB edge. The fully shrouded header with center key polarization prevents mismating, and the LCP (Liquid Crystal Polymer) housing provides high-temperature resistance for reflow soldering compatibility.","working_principle":"The 4304507 operates as part of the Molex Micro-Fit 3.0 connector system, which uses a crimp-and-insert approach for wire termination. The header features brass alloy contacts with gold plating over nickel underplating, providing excellent conductivity and corrosion resistance. The 8.5A per contact rating is achieved with the robust contact design and proper wire gauge selection (18 AWG recommended for maximum current). The 600V rating requires adequate creepage and clearance distances on the PCB, which the 3.0mm pitch provides. The LCP housing material withstands lead-free reflow soldering temperatures and operates continuously up to +105\u00b0C. The center key polarization feature ensures that only the correct mating housing (43025 series receptacle) can be inserted, preventing incorrect connections that could short power rails.","pin_description":"
