🚨 The AI boom is creating an unexpected bottleneck—and it's not GPUs. It's MLCC capacitors.

Everyone is watching GPUs and HBM memory. Few are paying attention to the tiny components that every AI server depends on.


Over the past few months, I've had conversations with friends working in finance, external auditing, and electronics manufacturing. Due to strict confidentiality obligations, they cannot disclose client names or sensitive business information. However, several independently described similar trends that caught my attention.


During external audits, auditors don't just verify financial statements. They also review inventory records, work-in-progress (WIP), production output, purchase orders, customer contracts, and order backlogs to verify that reported revenue and disclosures are supported by underlying business activity.


They understandably didn't share specifics, but the broad picture they described was remarkably consistent. When similar observations emerge across multiple manufacturers and different countries, it's worth paying attention.


One recurring theme was that production capacity appears to be increasingly directed toward higher-value AI-related products, while some traditional electronics programs are facing tighter component availability and longer lead times. Public reports and industry commentary available online point in the same direction, providing additional support for this trend.


One example mentioned during these discussions involved an electronics manufacturing company (EMS/EMC) that had to reduce production despite healthy customer demand because of MLCC shortages. The bottleneck wasn't labor, equipment, or factory capacity—it was the inability to secure enough of the required capacitors.

What's even more interesting is that similar observations have reportedly surfaced during audit work and manufacturing operations across Singapore, Malaysia, China, Taiwan, and Vietnam. For obvious confidentiality reasons, neither the auditors nor the companies involved can identify the businesses concerned.


While these observations are anecdotal rather than comprehensive industry data, they align closely with what leading component manufacturers have publicly communicated.


As AI infrastructure spending accelerates, Murata and other leading MLCC manufacturers are reportedly prioritizing production for AI servers, AI accelerators, high-speed networking equipment, and advanced power systems. The result is tighter supply for certain high-end MLCCs, longer lead times, and increasing pressure across the broader electronics supply chain.


Here's why it matters:


⚡ An AI server can contain 15,000–25,000 MLCC capacitors—far more than a traditional enterprise server.


⚡ Murata expects AI-related MLCC demand to grow by roughly 30% annually through 2030, making AI one of the fastest-growing end markets for advanced MLCCs.


⚡ As production increasingly shifts toward AI infrastructure, some consumer, industrial, automotive, and communications customers are experiencing tighter allocations and longer procurement cycles.


This isn't just about one supplier.


If demand continues to outpace capacity expansion, other major passive component manufacturers could also benefit as customers diversify sourcing:


• $Murata Manufacturing Inc.(MRAAY)$  

• Samsung Electro-Mechanics

• $Taiyo Yuden Co. Ltd.(TYOYF)$  

• Yageo.TW

• TDK

• $Kyocera Corp.(KYOAY)$  

$Vishay Intertechnology(VSH)$  

The AI revolution isn't only driving demand for GPUs, HBM memory, and optical networking.


It's reshaping the entire electronic component ecosystem—from advanced semiconductors down to the tiny ceramic capacitors that quietly power every circuit board.


Sometimes the smallest components become the biggest bottlenecks.


Taken individually, conversations with industry professionals don't prove a trend. But when those observations broadly align with public company disclosures, supply chain commentary, and market developments, they become difficult to dismiss.


The market isn't just rewarding AI chips anymore—it may soon reward every critical supplier in the AI hardware supply chain.

    @Ah_Meng @InverseCramer Muthu Boy's side hustle is being a karang guni boy. If you've got an old TV lying around, pass it to me—I need to harvest those precious MLCCs! 😄

      The bottleneck issue however is real. These passive components are used everywhere. The highest demand used to be mobile phones. When EVs come around, I have left the industry but I know they used lots too. TVs and other IoT devices use them too. With higher margins from AI, something got to give.

      This means AI customers are generally less sensitive to MLCC price increases if supply is constrained and the capacitors are not easily substitutable. That creates room for manufacturers to improve pricing and margins.

      If an AI board  costs $20,000, and MLCCs account for 1% of the BOM, that's about $200 worth of MLCCs.
      Even if MLCC prices doubled, the board BOM would only increase by about 1% overall.
      Compared with the cost of GPUs, HBM, and networking chips, that increase is relatively small.

      Do you know manufacturing MLCC used to my line of work? Murata was our main competitor. My firm was no. 2 in the world. I still remember for every component we sold, we were actually losing 1 cents… yes, both Murata and us sold passive components for about 5 cents each. We sell by Billions

    How time really changed? Something so dirt cheap is now treasured as AI gold! [Facepalm][Spurting] My ex-company could compete and was taken over by a major Japanese corporate. Itself got sold eventually to a big US corporate. Guess who? Qualcomm…
