How to stabilize nanosecond-level transient voltage in AI server CPU/GPU power supply?

For high-performance applications, we recommend using multilayer solid-state capacitors with ultra-low ESR characteristics, such as the YMIN MPS series, whose ESR can be as low as ≤3mΩ (@100kHz). During on-board verification, the voltage recovery speed can be observed through load step tests, or the impedance curve can be measured using a network analyzer.

How to filter MHz noise in AI server power systems?

High-quality low-ESR multilayer solid-state capacitors can achieve both low ESR and low ESL through optimized internal electrode structure. They maintain very low impedance in the 1MHz to 10MHz high-frequency range, resulting in excellent high-frequency noise filtering.

What capacitors are recommended for high-temperature environments in AI servers?

Multilayer polymer solid-state capacitors (such as the YMIN MPS series) exhibit excellent high-temperature stability, with ESR increase at 85℃ compared to 25℃ controlled within 15%, making them ideal for high-temperature, high-reliability scenarios.

How to ensure long-term reliability of capacitors in AI servers?

Solid-state polymer capacitors, especially high-performance multilayer types, maintain capacitance variation within ±10% across the entire temperature range (-55℃ to 105℃). After 2000 hours of continuous operation at 105°C, the capacitance decay is typically less than 5%.

What are the key parameters for capacitor selection in AI server VRMs?

Key parameters include: ultra-low ESR (≤3mΩ), high ripple current capability (≥8A @85°C), excellent temperature stability, long lifespan (2000+ hours @105°C), and batch consistency with ESR dispersion within ±10%.
