The 43045-1401 is a 14-circuit dual-row PCB header from Molex’s Micro-Fit 3.0 series. With a 3.0mm pitch and through-hole mounting with PCB polarizing pegs, this fully shrouded header delivers up to 8.5A per contact for wire-to-board power distribution in applications requiring higher circuit counts in the Micro-Fit 3.0 form factor.<\/p>\n

The 14-circuit count makes it suitable for applications requiring multiple power and signal connections in a single compact interface. The tin-plated brass contacts, LCP housing, and PCB polarizing pegs ensure reliable performance in demanding environments.","working_principle":"The 43045-1401 uses the standard Micro-Fit 3.0 contact system with fully isolated dual-beam terminals providing four points of contact per mating interface. The positive locking ramp engages with the mating receptacle housing to prevent accidental disconnection. The kinked solder pins provide mechanical retention to the PCB during wave soldering, while the LCP housing tolerates high-temperature lead-free reflow processes.","pin_description":"
