The tin-plated mating finish and phosphor bronze contacts are rated for 5 A per circuit at 110 V, with the 100.0 µin (2.54 µm) tin thickness providing a cost-effective contact surface for applications where moderate mating cycles are expected.
The tin-on-tin contact interface is rated for fewer mating cycles than a gold-plated equivalent — figure on a handful of insertions for board-level test and final assembly, not repeated field service.
