Core Applications in Server Power Supplies
VPW series capacitors play an irreplaceable role in server power supply systems:
Server Power Supply Unit (PSU): Modern server power supplies generally adopt high-frequency switching power supply technology. The low ESR characteristics of the VPW series significantly reduce power loss and improve power conversion efficiency. Its high ripple current handling capacity ensures stable voltage under load fluctuations, providing clean power to critical components such as the CPU and memory.
Motherboard Power Circuit: In the VRM (Voltage Regulator Module) of the server motherboard, VPW capacitors are used for filtering and energy storage. Their low ESR characteristics allow for rapid response to processor load changes, preventing voltage drops or overshoots, ensuring stable computing performance.
RAID Controllers and Network Interface Cards: These expansion cards are extremely sensitive to power quality. The high-frequency characteristics and stability of the VPW series effectively suppress noise interference, ensuring data transmission integrity.
Storage Device Power Supplies: In enterprise-level hard drive arrays and SSD power circuits, VPW capacitors provide stable decoupling and filtering functions, preventing voltage fluctuations from damaging the storage media and reducing the risk of data loss.
The advantages of Yongming's VPW series in the server field are not only reflected in the performance of individual components, but also in the improvement of system-level reliability. Servers typically require 24/7 uninterrupted operation, placing extremely high demands on the lifespan and stability of components. The VPW series has undergone rigorous high-temperature load life testing (105℃, 2000 hours) and high-temperature and high-humidity testing (60℃, 90-95%RH, 1000 hours), proving its ability to operate stably for extended periods in harsh environments, significantly improving the overall reliability and lifespan of the server.
Wide Range of Other Applications
Besides the server industry, Yongming VPW series aluminum electrolytic capacitors also excel in the following fields:
Industrial Automation and Control Systems
Industrial environments, such as inverters, servo drives, and PLCs, place extremely high demands on the temperature stability and durability of capacitors. The wide temperature range of the VPW series allows it to adapt to temperature fluctuations in factory environments, and its high ripple current capability is suitable for handling large current pulses in motor drives.
Communication Infrastructure
Base station power supplies, network switches, routers, and other communication equipment need to withstand outdoor temperature variations and power grid fluctuations. The high-temperature stability and low ESR characteristics of the VPW series ensure stable operation of communication equipment in various environments, reducing the risk of network outages.
New Energy and Power Electronics
In equipment such as solar inverters, wind power converters, and UPS power supplies, VPW capacitors are used in DC-Link circuits and output filtering. Their high-voltage versions (up to 50V) and low-loss characteristics help improve energy conversion efficiency.
Automotive Electronics
With the increasing electrification of automobiles, the VPW series can be applied to in-vehicle power supplies, ADAS systems, entertainment systems, and other scenarios. Its high-temperature resistance makes it suitable for high-temperature environments such as engine compartments.
Medical Electronic Equipment
Medical equipment has extremely high requirements for reliability and safety. The stability and long lifespan of the VPW series make it suitable for applications such as medical power supplies and monitoring equipment.
In-depth Technical Parameter Analysis
The Yongming VPW series offers a wide voltage range from 2.5V to 50V, with capacitance ranging from 47μF to 1000μF, meeting the voltage and capacitance requirements of different circuits. The compact product size (minimum Φ5×5.8mm) is suitable for high-density circuit board designs.
Taking the VPW 2.5V 1000μF model as an example, its ESR is as low as 7mΩ, and its ripple current withstand capability is as high as 6100mA, significantly better than conventional aluminum electrolytic capacitors. High-voltage models, such as the VPW 50V 47μF, maintain a low ESR of 50mΩ even at a 50V operating voltage, meeting the stringent requirements of high-voltage circuits.
Regarding leakage current control, the VPW series utilizes advanced materials and processes to ensure that after charging for 2 minutes at rated voltage, the leakage current remains below the standard value, reducing power loss and improving system efficiency.
