Multilayer ceramic capacitors (MLCCs), essential miniature components known as 'the rice of the electronics industry,' are in extremely short supply as demand from AI-driven server infrastructure fuels a steep drop in global inventory levels. This bottleneck is most acutely felt across China’s technology ecosystem, where manufacturers and distributors are racing to meet unprecedented consumption.
- MLCC inventory volumes dropped nearly 8% in August versus July.
- Average unit prices rose 13% year-on-year, increasing inventory value.
- AI server demand projected to grow 80% annually, stressing supply.
What happened
The global stockpile of multilayer ceramic capacitors (MLCCs) has fallen to historic lows as demand from artificial intelligence infrastructure surges worldwide. These tiny components, vital for electrical buffering on circuit boards, are increasingly used in high volumes within AI server hardware. By early August, worldwide distributor inventories had declined 8% compared to a month earlier, underscoring a continued supply shortage. The average price per unit also rose significantly, leading to a 10% increase in the total value of inventory despite shrinking volume.
Major manufacturers in Asia, including Murata Manufacturing from Japan and Samsung Electro-Mechanics based in South Korea, reported similar declines in stock levels. While they have been expanding production capacities, the pace of growth has yet to keep up with the rapid surge in demand. Analysts highlight this as the start of what could be the largest and longest supply cycle driven by the intense processing needs of modern AI data centers, especially impacting China’s technology supply chains.
Why it matters
MLCCs are often referred to as 'the rice of the electronics industry' due to their ubiquitous and essential role in electronic circuits. The current supply crunch creates a critical bottleneck, particularly for AI server manufacturers developing cutting-edge hardware. The spike in demand, now estimated to grow by approximately 80% annually for AI-grade capacitors, signals a structural shift in the electronics supply chain where passive components are gaining strategic importance beyond traditional memory chips and optical modules.
For China’s burgeoning AI and tech industries, this shortage poses risks of increased production costs, delays in hardware deployment, and potential vulnerability in the electronics ecosystem. As global investors and asset managers take notice, new financial products such as ETFs focused on MLCC manufacturers have emerged, reflecting growing market recognition of these components’ pivotal role in powering future AI infrastructure.
What to watch next
Industry watchers will be closely monitoring efforts by leading MLCC manufacturers like Murata and SEMCO to scale up capacity and innovate production techniques to alleviate shortages. Supply improvements or further disruptions could significantly influence market pricing, inventory levels, and hardware availability throughout 2026 and beyond.
Additionally, the evolution of AI hardware applications may continue to push demand for MLCCs higher, prompting broader supply chain realignment and increased investment in passive component manufacturing. China’s role as a major technology hub means its enterprises and policymakers will be pivotal in managing the impact of this supply crunch on AI infrastructure development and electronics manufacturing resilience.
