Through-hole shrouded header, 8 circuits
The 641213-8 is the 8-circuit member of the TE MTA-100 header line, a single-row board-to-cable/wire connector with a 0.100" (2.54 mm) pitch. The mating contacts are gold-plated (30.0 µin / 0.76 µm) for corrosion resistance across repeated mate cycles; the post contacts carry a tin-lead finish (150.0 µin / 3.81 µm).
Current rating and wire-gauge dependence
The current rating is specified as varying by wire gauge — the limiting factor is the termination, not the contact beam, so the per-circuit current follows the connected wire's ampacity.
