What this 9-position right-angle header does in the assembly
The 5-104361-8 is a 9-circuit, single-row, shrouded header from the AMPMODU MTE series. It mates with AMPMODU MTE receptacle housings and crimp contacts to create a wire-to-board or board-to-board interconnect.
Current, temperature, and environment — what the ratings actually mean
Rated 3A per contact at 25°C ambient. In a bundle of nine circuits carrying full current, the temperature rise inside the housing will be higher than a single-contact test — derate by 20-30% for dense harness runs.
Mating and termination — what fits and what doesn't
This header mates with AMPMODU MTE receptacle housings (e.g., 5-104363 series) and uses standard AMPMODU crimp contacts (part numbers 1-87456-0, 1-87456-1, etc.). Termination is solder through-hole — the 0.145" (3.68mm) post length is long enough for wave solder on standard 1.6mm PCBs. The keying slot in the housing prevents mismating with receptacles that have a different keying position.
