Board-to-Wire Power Header for Demanding Environments
The Molex 430451426 is a 14-position, dual-row male header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects. It carries an 8 A per contact current rating at a 600 V voltage rating, making it suitable for distributing power in automotive, industrial, medical, and telecommunications equipment. The 3.00 mm pitch provides adequate creepage for the voltage rating without forcing an oversized board footprint. The 30.0 µinch gold plating on the mating contacts supports repeated mating cycles in corrosive or field-service environments, while the tin-plated solder tails (100.0 µinch) ensure reliable wave-solder wetting. The shrouded 4-wall design with a locking ramp provides positive retention and protects pins from damage during handling and mating. Board locks on the through-hole version hold the header in place during wave solder and resist shear forces from cable strain. The UL94 V-0 liquid crystal polymer housing meets the flame rating required for equipment inside enclosures.
Mating Half and Termination
This header mates with the matching Micro-Fit 3.0 receptacle housing (e.g., the 43025 series) that accepts the crimp terminals. The locking ramp on the header engages the latch on the receptacle for a vibration-resistant connection. The through-hole termination with kinked pins provides secure mechanical retention on the PCB before soldering.
Sourcing and Lifecycle
The 430451426 carries an Active lifecycle status and is ROHS3 compliant.
