Board-to-Wire Header for Power and Signal
The Molex Micro-Fit 3.0 430452022 is a 20-position, dual-row header in the 43045 series, designed for board-to-cable/wire interconnects. Rated 8 A per contact with gold-on-mating-side and tin-on-post plating, it handles medium-current power and signal duty across automotive, industrial, medical, and telecom applications.
The 8 A per-contact rating is the headline power spec — each contact carries enough current for a moderate DC rail or a cluster of signal lines, but the real duty is governed by the gold mating finish (15.0 µ" on the mating side).
Mates with the Micro-Fit 3.0 receptacle housing (sold separately) using the matching crimp terminal — the locking ramp engages with the receptacle's ramp to prevent accidental disconnection.
