100V high capacitance value MLCC suggestion for 48V power systems
1210i, 10uF, 100V, X7S (CL32Y106KCVZNWE)

Abstract
With the increase of power consumption of data centers,a resulting trend is the adoption of more 48V powersystems. To support this growing demand of 48V powersystems, Samsung Electro-Mechanics offers a 1210i,
10uF, 100V, X7S MLCC which operates under higher
temperature conditions. In addition this MLCC is availablefor Industrial and robotics applications which are alsousing 48V power systems.

The Rise of TDP (Thermal Design Power) in CPU, Memory, GPU
The expansion of Artificial Intelligence (AI) driven by big data, data center companies are in needmore processing power, increasing their need for processors with a higher number of CPU cores.
The resulting TDP of server CPU’s has increased more than 70% for the past 3 years and expects toreach 350~400W in ‘22 for new server CPU.
Additionally, memory module TDP is increasing with the faster speed offered by DDR5 and is also
accelerating the consumption of power (See figure1).

Figure1. Server CPU and memory module TDP trend

In other applications like Machine Learning, the TDP within GPU and Tensor hardware accelerator
processor is also increasing, reaching almost 400W per processor.

Data center energy efficiency is not a currently a corporate problem, but a national issue.
The US Department of Energy (DOE) is starting to distribute guidelines for improving data center
energy efficiency.

The power required for the operation of servers
in data center’s accounts for more than 50%
of all their power consumption and is growing!

Expansion of 48V power systems
Many data center companies are converting to 48V systems, realizing good power conversion
efficiency, reducing their high power problems. is rapidly starting to trend with others toreplace their existing 12V systems. From the server system designer's point of view, as the input
voltage changes from 12V to 48V, this requires 100V high capacity MLCC to support.

Server system heat problem
Another issue plaguing the modern day server systems is the thermal issue. The number of CPU
cores is rapidly increasing and accelerators, high-performance graphic cards are also added, so theheat problem is quickly expanding.

Starting with Ice Lake, the number of DIMM modules
that can be supported per CPU has increased from12 to 16. As DDR5 now has its own onboard Voltage

Regulator (VR) the heat inside the system is rapidlyincreasing.
The adoption of high-temperature characteristic
MLCC’s will be required.

Available for AI robotics and network
Applications that require high power such as warehouserobotics using AI, may have four 12V batteries connected
in series and a 48V system is adopted. 48V power system
are also used in network equipment, which makes it
a good fit to use the high-reliability products fromSamsung Electro-Mechanics.
