What happened

Samsung Electro-Mechanics reportedly extended lead times for low-capacity, high-capacity, and automotive MLCCs from more than 30 weeks in September to 52 weeks in October; some customers were awaiting parts for approximately one year after placing orders.S1

Yageo’s lead times for main MLCC products were reported at 30 to 52 weeks, with the extension spreading from high-capacity, high-performance products into low-capacity and automotive items.S1 NIC Components, Viking, and Suncon Capacitors also experienced varying degrees of lead-time extension, while multiple companies continued price-increase trends.S1

AI servers were identified as a key source of demand growth because their MLCC usage could exceed 10 times that of standard servers.S1 Samsung Electro-Mechanics’ component division reached 91% capacity utilization in the first half of the year, and its Philippines expansion project was not expected to reach mass production until after 2027.S1 The source did not disclose the unit or component mix behind the 91% figure.S1

XAIPART take

Technical impact

XAIPART analysis: A 52-week interval can disrupt production schedules, prototype completion, and qualification plans where designers specify a single manufacturer or exact part number.

XAIPART analysis: Engineers should verify capacitance, voltage, dielectric, tolerance, package, automotive qualification, and lifecycle status before considering any substitution; the source does not provide approved alternate lists.

Market impact

XAIPART analysis: Buyers should treat the 52-week lead time as a planning constraint and obtain dated written quotations rather than relying on normal distributor stock assumptions.

XAIPART analysis: Safety-stock decisions should distinguish forecast demand from committed supply and compare the cost of holding inventory with the production risk of an open schedule.

Action

XAIPART analysis: Review open purchase orders, identify single-sourced MLCCs, request current lead times by MPN, and escalate any line whose promised delivery falls outside the product schedule.

XAIPART analysis: Engineering and procurement should document any approved second source before use, including electrical fit, mechanical fit, qualification requirements, and change-control approval.

XAIPART Forecast

XAIPART analysis: By , XAIPART expects at least one sampled Samsung Electro-Mechanics MLCC quotation to show a lead time above 30 weeks; if all sampled quotations are 30 weeks or less, this forecast is wrong. XAIPART analysis
