Product details

12-Circuit Right-Angle Header for Wire-to-Board Power

The Molex 0430451222 is a 12-circuit male pin header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects. It is a through-hole, right-angle mounted header with a shrouded 4-wall housing and a locking ramp for secure mating. The 3.00mm pitch and 0.118" row spacing give enough creepage for the 600V rating without forcing an oversized board footprint. Rated 8A per circuit at 600V, this header suits power distribution in automotive, industrial, medical, and telecom equipment. The UL94 V-0 liquid crystal polymer (LCP) housing holds up in enclosed assemblies where flame rating is required.

The locking ramp provides an audible click when fully seated.
