Summary of Conference Call Records Industry Overview - The conference call discusses the capacitor industry, specifically focusing on the use of capacitors in data centers and high-voltage direct current (HVDC) systems. The key components mentioned include the "horn capacitor" (a type of aluminum electrolytic capacitor), EDLC (Electric Double Layer Capacitor), and LIC (Lithium Ion Capacitor) [1][2][3]. Key Points and Arguments 1. **Data Center Upgrades**: The upgrade to GB300 in data centers aims to address customer complaints related to unstable power supply pulses by introducing active sub-card structures and advanced filtering components like supercapacitors, significantly reducing complaint rates [1]. 2. **Demand for Horn Capacitors**: The demand for horn capacitors is increasing due to higher system operating voltages, indicating a growing need for high-performance filtering components in high-voltage applications [1][10]. 3. **Capacitor Usage in Power Systems**: Capacitors are categorized into three levels in power systems: - Level 1: Input stage (200V or 300V) using aluminum electrolytic capacitors for initial purification and noise reduction. - Level 2: Medium voltage conversion (48V to 54V) where horn capacitors and supercapacitors may be used. - Level 3: Low voltage conversion (3.3V to 0.65V) requiring supercapacitors to ensure high purity and stability [3][4][5]. 4. **Cost Comparison**: The unit price of horn capacitors is approximately 50 yuan, while EDLCs range from 20 to 40 yuan. However, due to the larger capacity of horn capacitors, the actual cost is lower in high-performance applications [3][10]. 5. **Market Trends**: Major CSP manufacturers like Meta and Google are adopting horn capacitors and EDLC solutions, indicating a trend towards supercapacitor solutions in the industry [1][14]. 6. **HVDC Applications**: Horn capacitors are being considered for HVDC systems to improve ripple issues in power supply, with Meta and Google actively researching their implementation [2][17]. 7. **Future Demand**: The demand for horn capacitors is expected to continue increasing as system voltages rise, necessitating stronger filtering capabilities [10]. 8. **Competition Landscape**: The horn capacitor market is primarily dominated by Japanese companies, with domestic players like Jianghai actively participating in the competition [22][24]. Additional Important Insights - **Customer Complaint Reduction**: The introduction of active sub-card structures in data center designs allows for easier replacement of faulty components, reducing the need for complete system repairs and thus lowering customer complaints [6]. - **Capacitor Functionality**: Capacitors serve to filter and eliminate overshoot, protecting chips from damage and providing short-term energy storage [9]. - **Future Trends in Capacitor Demand**: There may be new demand points for capacitors, such as enhanced inductors on server boards, indicating potential opportunities for innovation in the capacitor market [32]. This summary encapsulates the critical insights from the conference call, highlighting the trends, challenges, and competitive landscape within the capacitor industry, particularly in relation to data centers and HVDC systems.
