TDK Unveils Industry-First 1608 Package 100V/1μF MLCC

TDK Corporation recently announced a major advancement in its commercial multilayer ceramic chip capacitor (MLCC) lineup. In a standard 1608 package (1.6mm × 0.8mm × 0.8mm), the company has achieved a 100V-rated capacitor with a capacitance of 1μF, featuring X7R temperature characteristics—the highest value currently available in this size category. The product officially entered mass production in June 2025.

Addressing the Demands of 48V Power Systems

As AI servers, energy storage systems, industrial equipment, etc. continue to put forward new demands for high energy efficiency and miniaturization, the 48V power supply architecture is gradually replacing the traditional 12V solution. As a key filter energy storage component, MLCC must provide a larger capacity at a high voltage level, and the package size must be as small as possible to adapt to the increasingly compact PCB design of the equipment.

Under the traditional 1608 package, the MLCC capacitance value has long remained at the 0.1μF level. TDK has increased it to 1μF this time, without the need to switch to a larger package (such as 2012), effectively solving the contradiction between miniaturization and large capacity, and can replace the traditional solution of multiple parallel MLCCs, greatly simplifying the circuit, saving space, and reducing energy consumption and failure rate.

Enhancing System Reliability and Power Efficiency

TDK's new MLCC has obvious advantages in high-frequency response and power conversion efficiency. Compared with multiple parallel connections, a single 1μF product has lower ESR/ESL and stronger parameter consistency, which helps reduce energy loss and suppress harmonic interference. It is particularly outstanding in high-reliability scenarios such as AI server power supplies, energy storage inverters, and industrial automation power supplies.

Widely used in AI, energy storage, industry, communications and other fields

Typical applications for this product include:

Artificial intelligence server: used for filtering the CPU power input to alleviate large current fluctuations;

Energy storage system inverter: filter out high-frequency harmonics on the DC side to improve the quality of power output;

Industrial controller (PLC): suppress voltage pulses caused by sensor switching and motor starting;

Communication base stations and charging piles: adapt to high-density and high-efficiency power supply environments.

Driving the electronics industry towards smaller, stronger and more reliable

The launch of this product not only fills the market gap of 100V/1μF in the field of small packages, but will also become an important driving force for the upgrading of 48V system electronic equipment. In the future, the company also plans to expand its product line to meet the needs of more diverse application scenarios.

In a space of less than 2mm², TDK has broken through the limitations of size and performance with technological innovation, bringing new possibilities to the electronics industry.
