Key to Power Stability in AI Data Servers: The Application of YMIN Capacitors
Power Requirements for AI ServersWith the rise of AI and high-performance computing, components in servers, such as processors and GPUs, demand increasingly higher power. This necessitates stricter requirements for server power supplies and related components.
Servers generally need to maintain an average mean time between failures (MTBF) of over 60,000 hours, provide wide voltage input, and ensure stable voltage and current output without downtime. During peak and valley fluctuations in data processing, they require robust instantaneous overload capacity to prevent issues like blue screens and system freezes. The integration of third-generation semiconductor materials, such as SiC and GaN power devices, also calls for the next generation of servers to be more compact while effectively managing heat dissipation.
In server power supplies, capacitors typically provide smoothing, DC support, and filtering during voltage input. They supply power at the DC-DC conversion stage and offer synchronized rectification and EMI filtering in rectification and filtering processes.
YMIN capacitors feature high capacitance density, compact size, low ESR, and strong ripple current tolerance, positioning them at the forefront of the domestic industry. They have partnered with renowned international manufacturer Navitas Semiconductor. Using Yongming's CW3 series capacitors, they developed a 4.5 kW server power supply that leads globally with an ultra-high power density of 137W/in and efficiency exceeding 97%, meeting the growing power demands of AI data centers with ease.

01 YMIN Capacitors Key Features:
- Long Lifespan, Stable Performance: YMIN capacitors can operate continuously for 24/7, meeting a 125 degrees C, 2000-hour lifespan standard with high reliability, significantly reducing maintenance needs. Capacitance remains stable, with a long-term change rate of no more than -10%, ensuring consistent performance.
- High Surge Current Endurance: Each YMIN capacitor can withstand surge currents over 20A, allowing server power supplies to handle overloads smoothly without causing blue screens, reboots, or GPU display issues.
- Compact Size, High Capacity: With reliable DC support and a miniaturized form factor, YMIN capacitors integrate seamlessly with third-generation semiconductor components like SiC and GaN, promoting power supply downsizing. Despite their small size, they offer up to 1200F capacitance at a 450V rating, ensuring strong current supply.
- Ultra-Low ESR and Ripple Endurance: YMIN capacitors achieve ESR values below 6m ohm , providing powerful filtering and minimal ripple temperature rise. Over extended periods, the ESR remains within 1.2 times the initial specification, reducing heat generation and enhancing energy efficiency while lowering overall cooling requirements for server power supplies.
