Server Applications: Core Application Scenarios of the MPD19 Series
Special Requirements of Server Power Systems
As the core equipment of data centers, servers require 24/7 uninterrupted operation, placing extremely stringent requirements on power systems: high stability, low noise, high efficiency, long lifespan, and strong transient response capabilities. Traditional electrolytic capacitors have a short lifespan at high temperatures and high ESR (Equivalent Series Resistance), making them unsuitable for the demands of modern server power supplies.
Advantages of the MPD19 Series in Server Power Management
Yongming's MPD19 series capacitors perfectly meet the specific needs of server power systems:
Low ESR Improves Power Efficiency
The MPD19 series boasts extremely low ESR values (as low as 4.5mΩ) at 100kHz, significantly reducing energy loss during power conversion and improving the overall efficiency of server power modules. In large data centers, even a 1% efficiency improvement can result in substantial power cost savings.
High Ripple Current Capability Ensures Stable Operation
Server CPUs and GPUs generate significant ripple currents during load surges. The MPD19 series' high ripple current handling capability (optimized through frequency correction factors) ensures stable power output, providing clean and stable power to critical server components.
Long Lifespan Reduces Maintenance Costs
The MPD19 series maintains a 2000-hour operating lifespan even at 105℃, far exceeding that of ordinary electrolytic capacitors. This significantly reduces maintenance frequency and operating costs in data centers, crucial for server applications requiring high reliability.
High-Temperature Stability and Harsh Environment Adaptability Server racks operate at high temperatures. The MPD19 series supports a wide operating temperature range of -55℃ to +105℃, maintaining stable performance even in the high-temperature environments of server clusters, without significant capacity fluctuations due to temperature variations.
