Ymin High-Voltage Capacitors Solve Three Major Challenges In AI Server Power Supplies

(MENAFN- Market Press Release) January 26, 2026 12:19 am - YMIN Electronics has launched the IDC3 series of high-voltage liquid horn-shaped aluminum electrolytic capacitors, providing an innovative technical solution to address industry pain points.

With the explosive growth of AI computing power, data centers are facing an unprecedented wave of upgrades. As the "power heart" of AI servers, the design level of the AC-DC front-end power supply directly determines the stability and continuity of computing power output. However, under the constraints of limited space, harsh high-temperature environments, and the trend towards higher frequency technologies, power supply design engineers are troubled by three major challenges. Shanghai Yongming Electronics (YMIN), with years of experience in the high-voltage capacitor field, has launched the IDC3 series of high-voltage liquid horn-shaped aluminum electrolytic capacitors, providing a perfect solution to the industry's pain points with its innovative technical solutions.

The AC-DC segment design of AI server power supplies and main power supplies for data centers has always faced three core challenges, becoming key bottlenecks restricting the improvement of power density and reliability:

1. **The sharp contradiction between space and capacity:** The limited space of a 1U rack-mount server imposes strict limitations on the size of components. Traditional horn-shaped capacitors cannot achieve sufficient energy storage capacity within a limited height, becoming the primary obstacle to high-power-density power supply design.

2. **Lifespan Test in High-Temperature Environments:** AI server rooms operate under consistently high temperatures, resulting in extremely high internal heat density in the power supply. The lifespan of a 450V/1400?F capacitor at 105? directly impacts the long-term reliability of the entire system. Short lifespan due to high temperatures is a common pain point in the industry.

3. **Performance Adaptation to the Trend of Higher Frequency:** The widespread adoption of new power devices such as GaN (Gallium Nitride) and SiC (Silicon Carbide) has driven a significant increase in power supply switching frequencies, commonly ranging from tens of kHz to hundreds of kHz (e.g., 120kHz). This places higher demands on the ESR (Equivalent Series Resistance) and ripple current carrying capacity of capacitors. Inappropriate adaptation can easily lead to system downtime.

Addressing industry pain points, Yongming's IDC3 series has undergone a comprehensive innovation from material formulation and structural design to manufacturing processes, redefining the performance ceiling of high-voltage capacitors:

(I) Density Revolution: Small Size, High Energy

Utilizing a compact?30×70mm horn-shaped package design, it perfectly fits the height constraints of a 1U server power supply, achieving a high capacitance output of 450V/1400?F within this size. Compared to traditional?30×70mm, 450V products in the industry, the capacity is increased by over 70%, successfully resolving the core contradiction between high-capacity requirements and space limitations.

(II) Lifespan Breakthrough: Stable Performance in High-Temperature Environments

Through optimized electrolyte formulation and anode foil structure, the IDC3 series maintains a load lifespan of 3000 hours even in harsh high-temperature environments of 105?. This design enables it to confidently handle the 24/7 operation of data centers, effectively solving the industry problem of rapid capacitor lifespan degradation in high-temperature environments and significantly improving system reliability.

(III) High-Frequency Adaptability: Keeping Pace with Semiconductor Technology Trends

Utilizing a low-ESR-specific design, it can handle higher ripple currents at 120kHz high-frequency operation, with a maximum single-chip ripple current of 4.12A (500V/1700?F specification), of which the 450V/1400?F specification has a ripple current of approximately 2.75A. This characteristic allows it to perfectly adapt to GaN/SiC high-frequency switching topologies, unlike traditional bus capacitors that primarily handle low-frequency ripple, and better meets the stringent high-frequency performance requirements of high-power-density power supplies.

Yongming Electronics has established deep technical collaborations with leading GaN power semiconductor manufacturers such as Navitas, completing comprehensive reliability and performance verification in AI server power supply projects ranging from 4.5kW to 12kW and higher power levels. This collaborative development model not only fully validates the product strength of the IDC3 series but also provides solid support for the technological evolution of mainstream AI server power supplies. Currently, the IDC3 series has become the preferred solution for several high-end AI server projects, with performance comparable to leading international brands.

To help engineers quickly identify suitable solutions, YM provides a simple and efficient three-step selection method:

1. Select the withstand voltage rating based on the bus voltage and allow for derating margin (450–500V rating recommended);

2. Determine the lifespan specification based on ambient temperature and thermal design (prioritize 105?/3000h specifications) and assess temperature rise;

3. Match product dimensions to space height and diameter constraints (e.g.,?30×70mm), while verifying ESR and high-frequency ripple current parameters.
