The SS8110 device database already covers over 120,000 component parameters, but what engineers truly care about is: which industries are adopting them on a large scale? Which suppliers have passed strict admission audits? Data shows that in 2025, the procurement share of SS8110 in the industrial automation sector surged by 47% year-on-year, while the update frequency of the supplier whitelist in the new energy track reached a quarterly level. This contradiction precisely reveals the core pain point of current selection decisions: complete data ≠ effective utilization, strict admission ≠ preci…
