Product details

The Molex 430451428 is a 14-position dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power and signal interconnects.

Rated 8 A per circuit and 600 V, this header handles moderate power distribution — think a main DC rail or a multi-circuit power bus inside a control cabinet. The tin-plated solder tails (100.0 µin) are standard for through-hole soldering. The board guide feature aids alignment during assembly.
