Global Shortage Hits Multi-Layer Ceramic Capacitor Markets - Supply Now Severely Restricted

The annual production of multi-layered ceramic capacitors (MLCCs) is believed to be in the region of one trillion pieces. Yet despite the sheer quantity of parts manufactured on a yearly basis, there is a global shortage.

In the past twelve months, the market for MLCCs through franchise distribution channels has been beset by continued lead time issues and price increases, with allocation slowly becoming an ever more prominent issue to contend with.

Many market analysts and media publications – backed up by our own research – indicates that this situation will not be resolved soon. The adage that demand dictates supply is, in this instance, out of the window.

The reasons for these current shortages are purely economic and can be found at both ends of the MLCC supply chain.

Electronic Component Lead Time Report (April 2018)

Continued high demand, coupled with many semiconductor manufacturers suffering from capacity constraints, has seen electronic component lead times increase in the past. And given current market situations, we believe that lead times for the majority of product groups will only move upwards in the coming weeks and months.

As buyers will likely be aware, the availability of many Vishay lines (particularly MLCCs and other popular lines) has severely decreased in recent weeks, with lead times of a year and above being quoted in some situations.

Vishay is not the only manufacturer to have pushed up lead times since our previous update, with Infineon, Nexperia and ON Semiconductor also posting noticeable increases.

Looking at specific product categories, critical supply levels remain across the industry, with IGBTs, Power MOSFETs and TVS/Protection devices particularly affected.

For an in-depth analysis, read our full report below and download our latest manufacturer lead time table.

In short

  • A large number of lead time changes for discrete semiconductors, check individual manufacturers and product lines for further information.
  • LED lead times remain at 20 weeks and above.
  • Due to continued high demand, Vishay has increase lead times for most of its products. Some parts are being quoted out at 52 weeks.
  • Overall availability of standard logic parts has improved slightly.


The analog sector looks to be something of an anomaly, given that most other product sectors have seen numerous lead time changes within the past month. Our information suggests that there has been little, if any, alterations when it comes to manufacturer or franchise lead times and availability.

However, despite this positive news, some sources are reporting that commodity prices are gradually increasing, and this cost could be passed on down the franchise supply chain in the coming months.


The overall supply of discrete semiconductor continues to be tight and this is beginning to seriously impact the availability of many popular product groups and lines.

Infineon, Nexperia, Toshiba and Vishay have all posted lead time increases this month, with power MOSFETs, and TVS/protection lines the most at risk.

Our information suggests that Nexperia has pushed out a blanket lead time rise, with all product families now being quoted out at 32 weeks, a rise of 6 weeks when compared to last month.

Vishay, too, has posted substantial lead time increases since our previous update. The Japanese manufacturer has been beset by capacity problems for some time now and the many of its discrete semiconductors are now being quoted out at a lead time of 39 weeks and above. Buyers relying on franchise distribution channels can now expect Vishay’s TVS/protection lines to be quoted out at 56 weeks (up 14 weeks) and lead times for power MOSFETs are now stated to be 44 weeks (a rise of 4 weeks).

Elsewhere in this sector, there are some bits of positive news. ON Semiconductor, ST and Texas Instruments have managed to reduce lead times for certain product groups. Though this is the exception rather than the norm.

However, Infineon has managed to make substantial lead time reductions for its thyristors and RF devices, with lines from the two product groups now being quoted out at 26 and 28 weeks respectively. This positive news is counteracted somewhat by marked increases for its bi-polar power (up 15 weeks) and small signal (up 5 weeks) items.

Historical issues within this sector, unfortunately, remain. General availability for IGBTs continues to be at a critical level, with manufacturer lead times of a year not all that uncommon.

Market analysts believe that the current situation is unlikely to improve in the immediate future, with Q4 2018 being quoted as the earliest that buyers can expect to see widespread positive movement.


Late last month, Micron confirmed that one of its manufacturing facilities had experienced delays in production due to a malfunctioning gas generation system. Although the problem has since been fixed and production has resumed, the temporary disruption is set to cause further turmoil in an already tight market sector.

All of Micron’s major memory products remain on allocation, but market insiders predict that prices will rise in the short-term. Avril Wu, research director of DRAMeXchange told EPSNews that they estimate any “increase would be higher than [their] previous forecast of 3 percent” but any such fluctuation would “only be temporary.”

Most of the major memory manufacturers are planning to up their production capabilities, something which should ease availability in the long run. That said, longstanding issues remain: DRAM supply is constrained, many NAND Flash lines are on allocation and EEProm devices lead times are slowly creeping upwards, with the average lead time now standing at 21 weeks.


Lead times for LEDs and other optical devices have stabilised in recent months, with our information suggesting little has changed regarding the availability of parts since our March report was published.

There is one exception, however.

As noted earlier, Vishay is experiencing supply problems across its portfolio and increased lead times for many of its popular lines. Looking solely at the opto market though, Vishay’s average lead time for coupler devices has increased from 24 weeks to 36 weeks in the past month.

DSPs & Microcontrollers

With demand for digital signal processors (DSPs) and microcontrollers (MCUs) continuing to be at exceptionally high levels, franchised distributors are continuing to request long-term purchasing forecasts from their OEM customers.

Due to this, we would still recommend purchasing departments to work alongside independent partners if they need to secure stock quickly. Although most franchised sources have managed to freeze lead times (albeit at a high level), Texas Instrument’s DSP lines are now being quoted out at 32 weeks.

Programmable Logic

After consecutive months of stability, Texas Instruments has increased lead times for its programmable logic product families to a high of 18 weeks. The other two major manufacturers in this area, Microchip and Xilinx, have kept their lead times static, though it’s worth noting that Microchip’s maximum lead time of 24 weeks is a sector high.

Standard Logic

Despite the market situation remaining tense, with general concerns about overall availability, lead times for standard logic components have decreased in the past month.

According to our information, franchise lead times for all Nexperia, ON Semiconductor and Texas Instruments products have all been cut by a fortnight since our last update. However, one word of warning: industry sources are claiming price increases are possible as we head towards Q2 2018.

As an independent stocking distributor, Cyclops Electronics can help purchasers of electronic components avoid lead time and allocation issues. With 189,756 stocked lines and access to available stock around the world, we can help you secure the parts you need when you need them.
