5G Base Station Technology Innovation: Key Role and Performance Advantages of YMIN Capacitors

01 Comprehensive Development in the 5G Era: New Requirements for 5G Base Stations!

5G base stations consist of BBU (Baseband Unit) and RRU (Remote Radio Unit). The RRU is typically positioned closer to the antenna, with optical fiber connecting the BBU and RRU, and coaxial cables connecting the RRU and antenna for information transmission. Compared to 3G and 4G, the BBU and RRU in 5G need to handle significantly increased data volumes, with higher carrier frequencies leading to unstable supply of direct current to the active chips. This necessitates low Equivalent Series Resistance (ESR) capacitors for filtering, eliminating noise, and ensuring smoother current flow.

In 5G base stations, YMIN stacked capacitors and conductive polymer tantalum capacitors are crucial components, providing excellent filtering functions and ensuring signal integrity. Stacked capacitors have an ultra-low ESR of 3mΩ, effectively filtering out noise from the power lines to ensure stability and enhance the quality and stability of the signal. Meanwhile, conductive polymer tantalum capacitors, due to their outstanding high-temperature performance and long-term stability, are particularly suitable for use in high-temperature environments of 5G base stations, supporting high-speed signal transmission and ensuring communication reliability and efficiency. The application of these high-performance capacitors is fundamental to achieving the high-speed, high-capacity capabilities of 5G technology.

A. Low ESR (Equivalent Series Resistance): Stacked capacitors and conductive polymer tantalum capacitors possess extremely low ESR, especially stacked capacitors achieving an ultra-low ESR of 3mΩ. This means they can reduce energy loss in high-frequency applications, improve power efficiency, and ensure the efficient operation of 5G base stations.

B. High Ripple Current Tolerance: Stacked capacitors and conductive polymer tantalum capacitors can withstand large ripple currents, suitable for handling current fluctuations in 5G base stations, providing stable power output and ensuring reliable performance under different load conditions.

C. High Stability: Stacked capacitors and conductive polymer tantalum capacitors demonstrate high stability, maintaining their electrical performance over extended periods. This is particularly important for 5G base stations requiring long-term stable operation, ensuring equipment reliability and longevity.

03 Conclusion
YMIN stacked polymer solid-state capacitors and conductive polymer tantalum capacitors possess features such as ultra-low ESR, high ripple current tolerance, and high stability. They effectively address the pain points of unstable power supply to active chips in 5G base stations, ensuring product longevity and reliability even under outdoor temperature fluctuations.
