The 5 A per-contact rating at the 0.100" pitch is typical for signal-level power distribution, but the buyer should note that running all 70 positions at full current simultaneously will push the temperature rise against the UL94 V-0 housing limit. The tin-on-tin mating finish (100 µ" on the contact side) is suited for applications with infrequent mating cycles — think permanent harness connections or field-service swaps measured in single digits over the product life.
Mating and Termination — What Connects Here
As an unshrouded header, this part has no polarization key or alignment shroud. Termination is solder-only — the 0.125" (3.18mm) post length fits standard 0.062" to 0.093" PCBs. The square male pins (phosphor bronze, tin-plated on the solder tail) provide a reliable solder joint for wave or hand-soldering processes. No crimp or press-fit option is available for this variant.
