Samsung Capacitor Waits Hit 61 Weeks as Prices Jump 23%

The manufacturer’s standard lead time for some Samsung Electro-Mechanics multilayer ceramic capacitors (MLCCs) listed on the electronics distributor DigiKey rose from 39 to 49 weeks in September to 61 weeks in October 2026, Korean outlet Newspim reported on 22 October 2026. A new order placed at that lead time would arrive at the end of December 2027, Newspim said.

Prices moved with the waits. Samsung Electro-Mechanics’ high-capacitance 47-microfarad MLCC rose from $17.50 per 100 units in August to $21.60 in October, about 23%, Korea’s Financial Post reported on 24 October, citing TrendForce. Newspim tied the longer waits to surging demand for high-value MLCCs used in AI servers.

Business Pill · LEAD TIME

A short explainer on lead time: why the wait is part of the price. It teaches the general idea only and says nothing about Samsung Electro-Mechanics or MLCCs.

What the Lead-Time Data Shows

MLCCs are small capacitors that store and release electricity on circuit boards. Newspim wrote that AI servers need high-capacitance, high-reliability MLCCs to supply stable power to high-performance chips, and that a few makers, led by Samsung Electro-Mechanics and Japan’s Murata, supply those parts.

Distributor-listed standard lead times; Newspim noted that actual lead times for volumes supplied directly to major device makers differ.

By iM Securities’ comparison, Samsung Electro-Mechanics’ lead times were about 3.6 times Murata’s and 2.2 times Yageo’s, Newspim reported. Financial Post said the 61 weeks applied to Samsung Electro-Mechanics’ seven main items, and that distributor stock of the 47-microfarad server power product from Samsung Electro-Mechanics and Yageo had been sold out for three months in a row.

Prices Are Rising at Two Suppliers

MLCC distribution prices for Samsung Electro-Mechanics and Yageo rose for four months in a row, while Murata, TDK and Taiyo Yuden froze prices over the same period, iM Securities found, according to Newspim. Samsung Electro-Mechanics was reported to have told Chinese sales partners in July that it would raise prices on some products by 30% from August shipments, Newspim said.

TrendForce expected in August that Samsung Electro-Mechanics would raise fourth-quarter MLCC prices to major device makers by 25% to 30% for consumer products and by 10% to 20% for AI server products, Newspim reported. TrendForce also put the company’s average MLCC selling price in the first half of 2026 up 13.9% from a year earlier.

Same Boom, Different Seats

The two big Korean parts makers are expected to report very different third quarters. FnGuide consensus as of 21 October put Samsung Electro-Mechanics’ third-quarter operating profit at 645.4 billion won, up 147.9% from a year earlier, and LG Innotek’s at 202.9 billion won, down 0.4%, Daehan Economic Daily reported.

LG Innotek’s revenue is expected to be about 1.6 times Samsung Electro-Mechanics’, but its operating profit about a third, Daehan Economic Daily wrote. The paper said LG Innotek’s business is concentrated on products supplied to Apple and that currency moves ate into its profitability; LG Innotek first showed an FC-BGA substrate for AI accelerators at the KPCA Show 2026 in September and aims to mass-produce it next year.

Customers Are Locking In Supply

Samsung Electro-Mechanics has disclosed seven long-term supply contracts since May, worth about 4.3 trillion won in total, Dailian reported on 20 October. The latest, signed on 19 October, is a 360.5 billion won deal with a large global customer for package substrates for high-performance memory chips, to be supplied in 2027. The customers were not named.

Daehan Economic Daily reported that the company is pursuing a 6.78 trillion won expansion of FC-BGA substrate capacity for AI servers at its Sejong site and in Vietnam, with the Sejong facility starting mass production in September 2028, and that customer investment support and medium-term volume commitments have eased the utilisation burden of the expansion.

From Chips to Capacitors

The capacitor waits add to the sold-out signals from larger AI suppliers. Amazon chief executive Andy Jassy said of AWS computing capacity that 2027 is largely sold out, and Lumentum’s chief executive said the optics maker is almost sold out for 2029, as our piece on the suppliers’ sold-out claims reported. Nvidia’s Vera Rubin spec page now lists 19.2 TB/s of HBM4 bandwidth per GPU, down from 22 TB/s in August, as our Vera Rubin bandwidth piece reported.

Financial Post reported that one board of Nvidia’s next-generation Rubin GPU carries about 12,000 components, and that TrendForce expects the parts shortage to peak in early 2027 as memory makers also stock up.

Investor Melvin (@MelvinInvests) summed up the sequence on X on 24 October: “First it was GPUs, then memory, then substrates, and now capacitors.” His post also said an AI server uses more than 10 times as many MLCCs as a regular server; none of the Korean reports we read gives that figure.

The Structural Read

As we read it, the wait is concentrated at one supplier: by iM Securities’ comparison, Samsung Electro-Mechanics’ lead times were about 3.6 times Murata’s and 2.2 times Yageo’s, Newspim reported.

As we read it, the prices follow the waits: distribution prices rose for four months at Samsung Electro-Mechanics and Yageo, while Murata, TDK and Taiyo Yuden froze theirs, according to iM Securities via Newspim.

As we read it, the profit split shows exposure, not scale: LG Innotek’s revenue is expected to be about 1.6 times Samsung Electro-Mechanics’, but its operating profit about a third, Daehan Economic Daily wrote.

Three Implications

FOR DEVICE MAKERS A new order at the 61-week DigiKey lead time would arrive at the end of December 2027, Newspim said; actual lead times for direct supply to major makers differ.

FOR SAMSUNG ELECTRO-MECHANICS FnGuide consensus put its third-quarter operating profit at 645.4 billion won, up 147.9%, Daehan Economic Daily reported; results are due on 28 October, Dailian reported.

FOR BUYERS LOCKING IN SUPPLY The company has disclosed seven long-term supply contracts since May, worth about 4.3 trillion won, Dailian reported; the customers are not named.

The Business Engineer Lens

This story maps onto the Business Engineer framework The AI Supercycle.

The analysis puts it this way: “Reading the map well means knowing where the constraint currently lives and where it is rotating to next.”

As we read it, the Korean reports show the constraint reaching passive components such as capacitors, as well as package substrates. The analysis was published in June 2026 and does not discuss MLCCs or Samsung Electro-Mechanics.

What Is Not Established

The 61 weeks is a distributor-listed standard lead time for some products, not the lead time in Samsung Electro-Mechanics’ direct contracts with major device makers, Newspim noted. The third-quarter profit figures are analyst consensus before results due on 28 October; Dailian, reporting on 20 October, gave the FnGuide consensus as 642.3 billion won. The long-term contract customers are not named. We did not contact Samsung Electro-Mechanics, LG Innotek, DigiKey, iM Securities or TrendForce.

The Bottom Line

Some Samsung Electro-Mechanics MLCCs now carry a 61-week standard lead time at DigiKey, up from 39 to 49 weeks a month earlier, Newspim reported on 22 October 2026. Its 47-microfarad server capacitor rose about 23% in price since August, Financial Post reported, and FnGuide consensus put the company’s third-quarter operating profit up 147.9% and LG Innotek’s down 0.4%.
