Eric Rimkeit, marketing director at Supplyframe, explains the reasons behind an anticipated spike in capacitor pricing and what it means for electronics supply chains. Capacitors, which perform fundamental functions in electronic products such as power stabilization and noise filtering, have traditionally been regarded as popcorn parts — small devices costing approximately three cents per unit. However, like the famous missing golden screw example that can halt an automotive production line, capacitors are critical to a product's operation. From a supply chain perspective, the passive component category comprises subcategories including MLCC (Multi-Layer Ceramic Capacitor), tantalum, aluminum electrolytic, and film capacitor. Murata, Samsung Electro-Mechanics, TDK, Yageo, Taiyo Yuden, KEMET, and AVX are the principal manufacturers in the global capacitor market.
Equally important to the broader electronics supply chain is their pricing. A new report from Supplyframe projects that capacitor demand will increase 14% quarter-over-quarter in the second quarter of this year. As a result, buyers of electronic products can expect to pay more as the additional costs are passed on to them. Rimkeit, however, states that the primary driver of price increases is artificial intelligence — particularly the new wave of data centers supporting it. Other areas affected by shifts in price and demand include aerospace and defense, medical devices, and industrial edge AI embedded in machinery within factory walls. From a supply chain perspective, the capacitor density in AI server cards is three to five times higher than in standard servers. NVIDIA H100, H200, and B200-based HGX systems require VRM (Voltage Regulator Module) and power delivery network (PDN) designs with hundreds of high-value polymer tantalum and MLCC components.
Over the past year, Rimkeit notes that capacitor pricing has declined an average of 31%. This is the result of excess inventories accumulated during the COVID-19 pandemic and design variations. However, for AI data centers, as demand for specific component types they require increases, expectations shift toward higher prices. From a supply chain perspective, a textbook example of the bullwhip effect has been observed in the capacitor market during the 2021-2024 period. Pandemic panic buying inflated safety stock levels between EMS (Electronics Manufacturing Service) and OEM providers to 18 months of consumption, followed by an inventory correction period during 2024-2025 creating price pressure. The proliferation of NCNR (Non-Cancellable Non-Returnable) contracts complicates risk management on the buyer side.
Capacitor manufacturers are attempting to diversify supply chains by shifting operations away from China, but according to Rimkeit, supply remains concentrated among a limited number of producers. From a supply chain perspective, capacitor manufacturing bases are distributed among Japan, South Korea, Taiwan, and China. Murata is opening new fabs in the Philippines and Thailand; TDK is expanding capacity in Vietnam; and Yageo is growing production in Mexico. Supply of BaTiO3 (Barium Titanate) dielectric powder and internal electrode materials containing palladium represent additional bottlenecks from a tier-2 raw material supplier perspective. Tantalum raw material is concentrated in the DRC and Rwanda under the 3TG (Tin-Tantalum-Tungsten-Gold) conflict mineral category and is subject to Dodd-Frank Section 1502 traceability requirements. As a result, Rimkeit's analysis is clear evidence that the AI wave is cascading throughout the lowest layers of the electronics supply chain.
Key Takeaways:
1. Supplyframe projects that capacitor demand will increase 14% quarter-over-quarter in Q2 2026.
2. The primary driver is AI data centers.
3. Capacitor prices have declined an average of 31% over the past year; the trend is reversing.
4. Other affected sectors include aerospace-defense, medical, and industrial edge AI.
5. Capacitor manufacturers are diversifying away from China, but concentration continues.
