The Molex 0430452202 is a 22-position (2×11) right-angle through-hole header from the Micro-Fit 3.0 43045 series. The 3.00 mm pitch and 0.118" row spacing give enough creepage for the 600 V rating without an oversized footprint, while the 30.0µin gold on the mating side handles repeated mating cycles better than a tin-plated alternative. Typical applications include automotive, industrial, medical, and telecom harness assemblies where the locking ramp and board lock keep the connection secure under vibration.
The 8 A per circuit rating is per-contact at the stated temperature rise.
