本文讨论MLCC（多层陶瓷电容器）市场交期因产品规格而分化：标准品交期稳定，而AI服务器用高容、高压等高端MLCC交期显著延长，部分接近10个月。文章引用TTI、Avnet Abacus、DigiKey等渠道数据，指出AI服务器需求是主要推动力，并预测高端MLCC交期将持续处于5-10个月，新增产能要到2026年Q4或2027年才能释放，厂商正提价并签订长期协议。与电子元器件供应链直接相关，反映高端被动元件供需失衡的结构性变化。
- 截至8月，标准尺寸MLCC交期一般为14-18周（约3.5-4.5个月）；高容、高压产品通常为15-20周（约4-5个月）。
- Avnet Abacus 2026年8月指引显示，多层贴片、高容和车规级MLCC交期为8至20周以上（约2-5个月），展望为稳定。
- ComponentNews将服务器用MLCC归类为严重短缺，村田和三星电机的产品交期超过20周，并预计下半年持续高位。
- DigiKey数据显示，高容类别中供应商差异大：三星电机部分产品平均交期约40周；村田1微法及以上高容MLCC交期从6月的24周升至7月的30周，部分渠道达36周。
- AI服务器所需高容、小型、高可靠MLCC数量是传统服务器的5到13倍，主要用于电源分配网络的去耦和滤波。
- 高端MLCC交期预计未来持续在5-10个月；新增产能推迟至2026年Q4或2027年，短期供需失衡难以解决。
供应链影响
- 高端MLCC供应紧张可能持续，采购方可能面临更长的提前期和更高的价格压力。
- 制造商提价和签订长期协议可能改变供应链中的议价动态，影响下游成本结构。
- 新增产能延迟可能使AI服务器和数据中心相关供应链在2026年前持续面临高端MLCC短缺风险。
- 标准品与高端品交期分化可能促使供应链调整库存策略，对高端品增加缓冲库存。
- 长期供应协议可能成为关键，取决于厂商产能分配和客户谈判能力。

多层陶瓷电容器（MLCC）市场的交期正因产品规格而急剧分化。标准组件保持相对稳定，而用于AI服务器的高容、高性能MLCC交期已显著延长。
根据TTI的交期趋势图，截至8月，标准尺寸MLCC通常为14至18周——约3.5至4.5个月。高容和高压产品通常报价为15至20周，即大约四到五个月。
Avnet Abacus的2026年8月交期指引同样将多层贴片、高容和车规级MLCC列为8至20周以上，即约两到五个月，其展望被归类为稳定。
然而，高规格产品正面临明显更紧张的供应环境。ComponentNews将服务器应用MLCC归类为严重短缺阶段，村田和三星电机的产品交期超过20周，并预计下半年持续高位。
DigiKey的交期数据也显示，在高容类别中，供应商之间存在显著差异。据报道，三星电机部分产品的平均交期在40周左右。对于村田，1微法及以上高容MLCC的交期在7月达到30周，高于6月的24周。部分分销渠道引用的交期高达36周。
这种分化的主要驱动力是AI服务器和数据中心需求的激增。AI服务器所需的高容、小型、高可靠MLCC数量是传统服务器的5到13倍，主要用于其电源分配网络中的去耦和滤波。
高端MLCC的交期预计在可预见的未来保持在5到10个月范围内。与以往周期不同，当时被动元件交期随整体经济状况更灵活调整，当前差距不被视为暂时繁荣，而是围绕AI基础设施的需求结构性重塑。
新增产能已推迟至2026年第四季度或2027年，使得短期内难以解决供需失衡。主要制造商也在提高价格，并越来越多地签订长期供应协议。
交期超过五个月并接近一整年表明制造商已达到无法快速提高产量的程度。它们也预示着更强的定价能力，以及向高价值产品提高盈利能力的加速转变。
“由于被动元件行业建设一条新生产线需要一到两年时间，今天的延长交期强烈表明供需失衡在短期内难以解决，”一位行业官员表示。“对于采购团队来说，建立缓冲库存和考虑长期供应合同不再是可选的——它们是必不可少的。”
Multilayer ceramic capacitors (MLCCs). AI-generated image
Lead times in the multilayer ceramic capacitor (MLCC) market are diverging sharply by product specification. Standard components remain relatively stable, while lead times for high-capacitance, high-performance MLCCs used in AI servers have stretched significantly.
According to TTI's lead-time trend chart, standard case-size MLCCs were generally running at 14 to 18 weeks—about 3.5 to 4.5 months—as of August. High-capacitance and high-voltage products were typically quoted at 15 to 20 weeks, or roughly four to five months.
Avnet Abacus' August 2026 lead-time guidance similarly listed multilayer surface-mount, high-capacitance and automotive-grade MLCCs at eight to more than 20 weeks, or about two to five months, with its outlook classified as stable.
High-specification products, however, are facing a markedly tighter supply environment. ComponentNews categorized MLCCs for server applications as being in a severe shortage phase, with lead times for Murata and Samsung Electro-Mechanics products exceeding 20 weeks and expected to remain elevated through the second half of the year.
DigiKey lead-time data also show substantial supplier-by-supplier differences in the high-capacitance category. Some Samsung Electro-Mechanics products were reported to have average lead times in the 40-week range. For Murata, lead times for high-capacitance MLCCs of 1 microfarad or more reached as long as 30 weeks in July, up from 24 weeks in June. Some distribution channels have cited lead times of up to 36 weeks.
The main driver of this divergence is surging demand from AI servers and data centers. AI servers require more than five to 13 times as many high-capacitance, compact and highly reliable MLCCs as conventional servers, largely for decoupling and filtering across their power-delivery networks.
Lead times for high-end MLCCs are expected to remain in the five- to 10-month range for the foreseeable future. Unlike previous cycles, when passive-component lead times adjusted more flexibly with broader economic conditions, the current gap is being viewed not as a temporary boom but as a structural reshaping of demand around AI infrastructure.
New capacity additions have been pushed back to the fourth quarter of 2026 or into 2027, making it difficult to resolve the supply-demand imbalance in the short term. Major manufacturers are also raising prices and increasingly entering into long-term supply agreements.
Lead times extending beyond five months and approaching a full year indicate that manufacturers have reached a point where they cannot quickly increase output. They also signal stronger pricing power and an accelerating shift toward improved profitability from higher-value products.
“Because it takes one to two years to build a new production line in the passive-component industry, today's extended lead times are a strong indication that the supply-demand imbalance will be difficult to resolve in the near term,” an industry official said. “For procurement teams, building buffer inventory and considering long-term supply contracts are no longer optional—they are essential.”
