Week 11, 2026 — Electronics Component Industry Highlights

📅 (2026/03/09 – 2026/03/15)

🌏 Global Industry Overview (Week 11)

Week 11 reinforced a clear theme: power conversion + monitoring + automotive/industrial controltook center stage, while protection/ESD pricing stayed volatileand DRAM inventory signals remained extreme. Demand surges clustered heavily around DC/DC modules (TPS82xx / TPS81xx), motor/industrial control (TMS320F28377), and sensing + precision data paths (ADS1220)—a classic signature of AI infrastructure power rails + industrial automation ramp.

🔹 Power Modules Went Into “Allocation Mode”
The biggest demand surges were dominated by compact buck modules and power-stage parts (TPS82140, TPS81256, TPSM82822, LM5163, LM5013). This is usually what demand looks like when customers are pushing for higher power densitywhile trying to keep BOM footprint under control.

🔹 Control + Precision Signal Chains Re-accelerated
TMS320F28377DPTPT (+578.71%) and ADS1220IPWR (+457.10%) point to stronger activity in motor control, instrumentation, and industrial sensing—often late-stage build signals (not just early R&D).

🔹 ESD / Protection Stayed “Price-Noisy”
Protection and discretes again delivered both sharp price increases (PESD5V0L2BT +270%) and sharp price declines (PESD5V0L1BAdown hard). That kind of dispersion typically reflects channel repricing + substitution + spot coverage behavior, not a stable supply environment.
