🧭 Cerametronics Weekly Insight
Week 41 marked a broad-based rebound following Q3 inventory corrections. Surge in CAN transceivers (ISO1050), low-end STM32 MCUs, and precision analog signals a strong restart of small-scale production and prototyping.

RF and connectivity components showed consistent demand growth, while inventory data revealed active restocking of interface and regulator parts, offset by deep drawdowns in analog front-end and power modules.

For buyers, the trend suggests early Q4 restabilization — focus on interface ICs, RF front-ends, industrial sensors, and discrete protection devices to secure allocation before year-end tightening.
