Passive components have become another pressure point in AI hardware costs, and Panasonic (TSE: 6752) is the latest to move. Effective July 2026, Panasonic will raise SP-Cap prices, its conductive-polymer aluminum capacitors, by 5% to 30% depending on spec. The stated reasons are silver and copper costs climbing alongside higher manufacturing and equipment spending, with Panasonic telling customers it is near the limit of what it can absorb. This follows the tantalum capacitor increases of roughly 15% to 30% it pushed through late last year.
AI servers carry ten to fifteen times the MLCC count of a general-purpose server, somewhere between 20,000 and 440,000 parts per box, and high-capacitance low-ESR types make up more than 60% of that. SP-Caps and high-end MLCCs handle accelerator power delivery and decoupling, the part of the board AI chips stress hardest.
Lead times on high-capacitance, high-voltage MLCC have stretched from about four weeks to twenty, with some parts simply out of stock. Murata's (TSE: 6981) new high-end plant is not finished until the end of 2026, and output is unlikely before Q4. So the price actions keep coming: Murata raised 15% to 35% in March, Taiyo Yuden (TSE: 6976) 6% to 13% in May, and Samsung Electro-Mechanics (KRX: 009150) is weighing up to 10%.
The pricing power is concentrated where AI competes most directly, in the small high-cap parts used for GPU decoupling. Buyers there are shifting off just-in-time ordering toward long-term agreements to secure supply through 2026.
For PC hardware, the direct effect is less certain. Motherboards, GPUs, and SSDs also use MLCCs and polymer capacitors, but the strongest pricing power is concentrated in the compact high-capacitance parts used around AI accelerators. That could add some board-level cost pressure, though the cited figures do not establish a broad rise in consumer hardware prices.
