SANTA CLARA, CA — October 24, 2026: The global shortage of passive electronic components — which began six months ago with high-capacitance MLCCs driven by AI server demand — is now spreading across the passive spectrum. Viking Tech reported this week that average lead times for its precision thin-film and standard thick-film resistors have reached 25 weeks, with some orders already scheduled into the second half of 2027. Samsung Electro-Mechanics, meanwhile, confirmed earlier in October that its entire MLCC portfolio — including low-capacitance, high-capacitance, and automotive grades — has stretched to 52 weeks. And on October 21, Meritz Securities data cited by the Wall Street Journal showed Taiwan-based YAGEO's MLCC lead times climbing to 30–52 weeks across the board.
What began as a focused shortage of high-value components is maturing into a systemic shortage of low-cost passive components — resistors, connectors, inductors, and electronic cloth — that collectively sit on every BOM but are rarely treated as strategic commodities. For industrial automation OEMs and spare-parts teams alike, the lesson is clear: a $0.01 resistor can stop a $200,000 production line just as effectively as a missing GPU.
1. Where We Are — A Lead-Time Snapshot as of October 2026
The passive component shortage has now entered its second phase. The first wave, which struck in early 2026, was tightly focused on high-capacitance MLCCs for AI servers. The second wave, now unfolding, is spreading across form factors and component types. The data tells the story clearly.
| Component Category | Manufacturer | Lead Time (Oct 2026) | Direction | Primary Driver |
|---|---|---|---|---|
| MLCC (all grades) | Samsung Electro-Mechanics | 52 weeks (full year) | ↑ from 30+ weeks (Sep 2026) | AI servers, automotive |
| MLCC (all grades) | YAGEO (Taiwan) | 30–52 weeks | ↑ extended throughout 2026 | AI servers, industrial control |
| MLCC (Japan OEMs) | Taiyo Yuden / Murata | 40–52 weeks | ↑ steady 4–6 weeks per month | AI servers, automotive ECU |
| Resistors (precision thin-film) | Viking Tech | 25 weeks | ↑ from 15 weeks (May 2026) | AI power, industrial, aerospace |
| Resistors (thick-film SMD) | Multiple suppliers | 18–25 weeks | ↑ steady | AI servers, industrial electronics |
| Resistors (automotive) | YAGEO, Vishay | 20–30 weeks | ↑ sharp acceleration Q3 2026 | EV, power electronics |
| Connectors (high-current power) | Amphenol, TE Connectivity | 22–32 weeks | ↑ Q3 2026 | AI server power racks |
| Electronic cloth (玻纤布) | Changchun Taiwan etc. | Supply up 228% YoY price surge | ↑ extreme | CPI substrate, PCB for AI servers |
2. Why AI Is Pulling This — The Multiplier Effect on Passives
The conventional view of AI-driven component demand focuses on GPUs, HBM, and high-end processors. But modern AI infrastructure consumes passive components at multiples the rate of conventional systems. A single NVIDIA H100 DGX SuperPOD can require 4–5x more MLCCs, 3–4x more power resistors, and 2–3x more high-current connectors than a comparably sized conventional server cluster — due to the power-delivery architecture required to feed and cool 800W GPUs.
Viking Tech's quarterly results put it in numbers: AI-related revenue reached 12% of Q1 2026 revenue, up from less than 5% in the same quarter of 2025, with a book-to-bill ratio of 1.5 — meaning 50% more orders are coming in than capacity can ship. The pressure is concentrated in 1206 and 0603 package sizes, the most common surface-mount resistor form factors — meaning the shortage hits an enormous installed base of industrial electronic designs rather than a single niche product line.
3. Price Hikes — The 2026 Timeline and What's Coming
Lead-time extensions are already being followed by price increases. The passive component price-hike cycle of 2026 has been the longest and most coordinated in a decade, with five major manufacturers issuing formal price letters between February and August.
| Date | Manufacturer | Price Hike | Scope |
|---|---|---|---|
| Feb 28, 2026 | Murata | 15–20% | High-capacitance AI-server MLCCs |
| Mar 12, 2026 | Samsung Electro-Mechanics | 25–35% | AI-server MLCCs |
| Jun 20, 2026 | YAGEO | 50% average, up to 150% | Full MLCC portfolio |
| Aug 1, 2026 | Samsung Electro-Mechanics | 30% across-the-board | Entire MLCC portfolio — industrial control, automotive, consumer, AI servers (no product exempted) |
| Aug 15, 2026 | Taiyo Yuden | 20–30% | AI server + automotive MLCCs |
| Aug 2026 | Samsung Electro-Mechanics | Spot prices surged 280% in a single month | Some tightly constrained MLCC specifications |
Perhaps the most striking data point: Samsung Electro-Mechanics signed a KRW 1.0722 trillion (USD 780 million) one-year supply contract with an unnamed "global major corporation" — the largest MLCC supply contract in the company's history — covering AI server MLCC deliveries from January to December 2027. This contract locks up a significant portion of Samsung's 2027 high-capacitance MLCC capacity before most OEMs have even finalized their 2027 BOMs.
4. Structural Divergence — Premium vs. Commodity
Not all passive components are equally constrained, creating a structural divergence that procurement teams must navigate carefully.
| Segment | Status | Why |
|---|---|---|
| High-cap MLCCs (≥10μF, X7R/X5R) | Extreme — 40–52 weeks | AI server power decoupling, automotive ECU |
| Automotive MLCCs (AEC-Q200) | Tight — 30–40 weeks | EV, ADAS, power electronics |
| Standard MLCCs (0805/0603, ≤1μF) | Moderate — 18–25 weeks | General industrial, consumer electronics |
| Thick-film resistors (0603/1206) | Tight — 18–25 weeks | AI server power, industrial sensing |
| Thin-film precision resistors | Tight — 25 weeks | Industrial control, aerospace, medical |
| High-current power connectors | Tight — 22–32 weeks | AI server power delivery |
| General-purpose ceramic capacitors | Loose — 8–12 weeks | Low AI exposure, mature capacity |
The critical takeaway for industrial OEMs: low-cost commodity passives are not immune. Viking Tech's 25-week lead times apply to both high-precision thin-film resistors AND standard thick-film SMD resistors — precisely the commodity parts most industrial BOMs use by the hundreds or thousands. The shortage is driven not by a single high-value specification, but by AI infrastructure pulling demand through the entire passive component ecosystem.
5. What This Means for Industrial Automation OEMs
For industrial automation OEMs — those building PLCs, VFDs, robot controllers, and edge-gateway systems — the passive-component shortage is not just a procurement concern; it is a strategic product-development concern.
BOM cost inflation is here to stay. MLCC price hikes of 15–30% and resistor lead-time extensions are now structural rather than temporary. A mid-range VFD that historically carried ~$12 in passive-component cost per unit may now require ~$18–$22 — a 50–83% increase — while its selling price is constrained by competitive pressure. OEMs are already adjusting 2027 budget forecasts upward by 8–15% to account for passive-component inflation.
Design-for-sourcing is becoming non-negotiable. OEMs that historically specified "best-in-class" passive components by brand may now find those exact parts have 40-week lead times. Substitution is possible in principle but requires engineering qualification — a weeks-long process for temperature-coefficient, tolerance, and voltage-rating changes that automotive, medical, and aerospace certifications cannot skip. The current procurement best practice: specify two or three qualified sources for every critical passive component, and pre-register substitutes in your BOM management system.
Inventory strategy inversion. OEMs traditionally kept inventory of expensive, strategic components (CPUs, power modules) and let distributors hold inventory of cheap passives. That calculus is now inverted. A $0.01 resistor with a 25-week lead time can delay a production run more effectively than a $50 ControlLogix processor, because most OEMs carry adequate CPU buffer stock but no backup passive-component inventory at all.
AutoDCSTech maintains a growing catalog of passive components — including MLCCs, power resistors, signal resistors, inductors, and high-current connectors — sourced directly from authorized distributors globally. If you need passive component cross-referencing, lead-time verification, or help locking in stock before 2027 capacity fills, our specialists can help.
6. 2027 Outlook — Four Factors to Watch
Will passive-component shortages persist into 2027? Four factors will determine the trajectory.
- Samsung's 2027 contract signal. The USD 780 million deal is the largest MLCC contract in the company's history and covers the entire 2027 calendar year. That contract — and others Samsung is almost certainly negotiating — sets a ceiling on 2027 available capacity for non-contracted customers. If you are an OEM without a 2027 long-term supply agreement, securing one now is urgent.
- Murata's capacity investment cycle. Murata is investing JPY 50 billion in new MLCC capacity, with construction of the Saga Plant Phase 2 expected to begin in 2026 and production ramp-up targeted for late 2027. This is the first significant capacity addition from a top-three manufacturer in this cycle, and the timeline suggests relief will not materialize before the end of 2027.
- AI server demand trajectory. The 2026 passive shortage is directly driven by data-center capex. If hyperscaler AI investments accelerate (as AWS, Microsoft Azure, and Google Cloud have indicated for 2027), demand will outpace any capacity increases for at least another year. If demand decelerates — a scenario analysts rate as low probability — lead times could soften by mid-2027.
- Consumer electronics spillover. Samsung's across-the-board 30% hike — including consumer-electronics MLCCs — signals that capacity allocation has fully shifted toward industrial and AI applications. Consumer electronics OEMs will likely either accept 30%+ price increases or shift to lower-spec MLCCs, creating a two-tier market that benefits industrial OEMs but penalizes consumer brands.
7. Bottom Line
The passive-component shortage is no longer a narrow issue affecting high-value AI-server parts. It has matured into a systemic shortage spanning MLCCs, resistors, connectors, and even electronic cloth — driven by AI infrastructure pulling demand through the entire passive component ecosystem. For industrial automation OEMs, three priorities stand out:
- Lock supply for 2027 now. Non-contracted capacity in 2027 is disappearing. If your BOM includes MLCCs, power resistors, or high-current connectors, a long-term supply agreement with an authorized distributor or direct OEM may be non-negotiable.
- Audit your BOM for single-source passives. Any MLCC, resistor, or connector that you currently specify from a single supplier should have at least one qualified substitute registered in your BOM management system. Engineering qualification now saves weeks of production delay later.
- Reassess inventory strategy. Cheap does not mean unimportant. Review every BOM for the highest-leverage "last-in-line" passive components — the parts that, if missing, stop your final assembly line.
