Newbie level 6

As AI servers move towards higher computing power, high power and miniaturization of power supplies have become key challenges. In 2024, Navitas launched GaNSafe™ gallium nitride power chips and third-generation silicon carbide MOSFETs, STMicroelectronics launched a new silicon photonics technology PIC100, and Infineon launched CoolSiC™ MOSFET 400 V, all to improve the power density of AI servers.
As power density continues to rise, passive components need to meet the stringent requirements of miniaturization, large capacity, and high reliability. YMIN works closely with partners to create high-performance capacitor solutions for higher-power AI server power supplies.
PART 01 YMIN and Navitas cooperate deeply to achieve collaborative innovation
Faced with the dual challenges of miniaturized design of core components and ultra-high energy density posed by the power supply system, YMIN continued to invest in research and development and innovation. After continuous technological exploration and breakthroughs, it finally successfully developed the IDC3 series of high-voltage horn-type aluminum electrolytic capacitors, which were successfully applied to the 4.5kW and 8.5kW high-density AI server power solutions released by Navitas, the leader in gallium nitride power chips.
PART 02 IDC3 Horn Capacitor Core Advantages
As a high-voltage horn-shaped aluminum electrolytic capacitor specially launched by YMIN for AI server power supply, the IDC3 series has 12 technological innovations. It not only has the characteristics of withstanding large ripple current, but also has a larger capacity under the same volume, meeting the strict requirements of AI server power supply for space and performance, and providing reliable core support for high power density power supply solutions.
High capacity density
In view of the problem of increased power density of AI server power supply and insufficient space, the large capacity characteristics of the IDC3 series ensure stable DC output, improve power efficiency, and support AI server power supply to further improve power density. Compared with conventional products, the smaller size ensures that it can provide higher energy storage and output capabilities in limited PCB space. At present, compared with international leading peers, YMIN IDC3 series horn capacitors have a volume reduction of 25%-36% in products of the same specifications.
High ripple current resistance
For the AI server power supply with insufficient heat dissipation and reliability under high load, the IDC3 series has stronger ripple current bearing capacity and low ESR performance. The ripple current carrying value is 20% higher than that of conventional products, and the ESR value is 30% lower than that of conventional products, making the temperature rise lower under the same conditions, thereby improving reliability and life.
Long life
The life span is more than 3,000 hours in a high temperature environment of 105°C, which is particularly suitable for AI server application scenarios with uninterrupted operation.
PART 03 IDC3 capacitor specifications and application scenarios

Applicable scenarios: Suitable for high power density, miniaturized AI server power solutions
Product certification: AEC-Q200 product certification and reliability certification from third-party international organizations.
END
IDC3 series horn capacitors have become the key to solving the pain points of AI server power supplies. Its successful application in Nanovita's 4.5kw and 8.5kw AI server power solutions not only verifies YMIN's leading technical strength in high energy density and miniaturized design, but also provides key support for the improvement of AI server power density.
YMIN will also continue to deepen its capacitor technology and provide partners with better and more efficient capacitor solutions to work together to break through the power density limit of AI server power supplies, facing the upcoming 12kw or even higher power AI server power era.
