Product details

Board-to-wire power header for harness assemblies

The Molex 430451013 is a 10-position, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects in automotive, industrial, medical, and telecom equipment. The 8 A per circuit rating means each contact carries bus-level current — sized for a power rail, not just a signal line. The gold mating finish at 15.0 µin (0.38 µm) supports repeated mating cycles in field-serviceable harnesses, while the tin-plated solder tails (100.0 µin / 2.54 µm) provide a reliable through-hole solder joint.

Frequently asked questions

What is the current rating of the Molex 430451013?

The 430451013 is rated 8 A per circuit. That 8 A per contact is the current each pin can carry continuously at the rated temperature rise, making it suitable for power distribution within a harness.

What is the pitch of the Molex 430451013?

The 430451013 uses a 3.00 mm (0.118 inch) pitch on both the mating interface and the row spacing. This pitch provides enough creepage for the 600 V rating while keeping the board footprint compact.
