📊 Week 13, 2026 — Electronics Component Industry Highlights

📅 March 23 – March 29, 2026

The market is no longer moving in one direction.
High-end parts are tightening.
Low-end components are being cleared out.

That was the real story of Week 13.

While AI infrastructure, memory bandwidth, and power-density parts kept attracting demand, many legacy discretes and protection devices entered aggressive price and inventory correction.

In other words:

Customers are still buying.
But they are buying more selectively.
And they are concentrating spend on performance-critical components.

🌏 Global Industry Overview

Week 13 showed a clear split across the supply chain.

On one side, demand remained active in:

• Memory
• Power management
• Analog
• FPGA
• RF infrastructure

On the other side, lower-end devices such as discretes, ESD, and protection parts saw heavy liquidation pressure.

At the same time, upstream cost pressure continued to build.

Copper moved above $10,000/ton, and that matters far beyond raw materials alone.

It raises pressure on:

• Connectors
• PCB layers
• Power-related BOM cost
• Quoting stability

So this week was not just about demand.

It was also about which parts still have pricing power.

📈 Top Demand Models

The highest search-volume models this week were still dominated by the familiar core basket:

1. STM32F405RGT6 ↓ 44.06%
2. STM32F103C8T6 ↓ 25.07%
3. ICM-42688-P ↓ 9.35%
4. W25Q128JVSIQ ↑ 3.48%
5. TPS5430DDAR ↓ 32.19%
6. STM32F407VET6 ↓ 17.50%
7. MT41K256M16TW-107:P ↑ 2.49%
8. STM32F103RCT6 ↓ 9.16%
9. TPS82130SILR ↓ 46.63%
10. TMS320F28335PGFA ↓ 50.16%

Read-through:
The headline leaders cooled, but the core demand base did not disappear.

It simply rotated.

Search volume pulled back on some anchor MCUs and power modules, while new momentum formed in more targeted system-build components.

🚀 Top Demand Surges

This is where the more important signal appears.

The strongest demand surges were:

1. W25X10CLUXIG ↑ 442.57%
2. CSD88584Q5DC ↑ 344.37%
3. EP4CE40F23I7N ↑ 318.42%
4. UCC28881DR ↑ 306.54%
5. OPA140AIDBVR ↑ 299.03%
6. BSC123N08NS3G ↑ 288.18%
7. AFT27S006NT1 ↑ 274.87%
8. TLV3201AIDCKR ↑ 273.83%
9. TPS552872RYQR ↑ 252.32%
10. MT41K512M16HA-125:A ↑ 248.67%

What does this tell us?

This is not a random mix.

It points to demand building around:

• Flash
• Power conversion
• Precision analog
• FPGA
• RF devices
• Legacy DRAM support

That is a classic sign of active platform build activity.

Not broad panic-buying.
Not passive replenishment.
But real, design-driven demand.

Market read

This is a very clear split.

Power ICs and Flash are pushing upward.
Discretes and protection lines are being repriced downward.

That usually means one thing:

The channel is separating high-value build demand from excess low-end inventory.

Read-through

Inventory is moving in two very different directions:

Memory + power + control parts are being stocked.
Certain high-end modules, sensors, and FPGA lines are being consumed fast.

That combination usually signals:

• selective restocking
• continued build activity
• and tightening in specialized applications

🧭 Cerametronics Weekly Insight (Week 13)

Week 13 was not a broad bullish week.

It was a selective quality-demand week.

That distinction matters.

The strongest signals came from parts tied to:

• power density
• memory support
• analog precision
• FPGA logic
• RF infrastructure

Meanwhile, lower-end discretes and protection families saw heavy correction, suggesting that large parts of the market are still working through excess inventory.

So the takeaway is simple:

Demand is still there.
But it is no longer spread evenly.
It is moving toward the parts that matter most in real system builds.
