On September 17, 2025, Heyue Electronics launched a series of low-impedance aluminum electrolytic capacitors, HY-LZ Series. This series of products uses high-purity glycol-based electrolyte formulation, three-dimensional honeycomb structure etched anode foil and new conductive polymer cathode materials to keep the ESR value stable in the full temperature range of -40°C~125°C 12mΩ or less. In the comparative test of a brand of 5G base station power module, the overall efficiency of the system increased from 89.3% to 91.7% after using this series of capacitors, and the new energy vehicle OBCs The application case shows that the capacitor temperature rise is reduced by 18°C, directly extending the life of the power device by about 30%.

1. Analysis of technical highlights

The three core technologies mentioned in the news together form the basis of the high performance of this series of products:

1. High purity glycol-based electrolyte: Improving the ionic conductivity and stability of the electrolyte in a wide temperature range (especially at low temperatures) is the key to maintaining low values in the entire temperature range.

2. Three-dimensional honeycomb structure etched anode foil: Significantly increases the effective surface area of the electrode, which significantly improves the volumetric efficiency and frequency characteristics of the capacitor, helping to reduce ESR.

3. New conductive polymer cathode material：替代传统电解液或作为补充，能极大降低阴极部分的等效串联电阻，是达成超低ESR（<12mΩ）的核心创新。

2. Interpretation of performance data

The published data is very convincing and directly hits the pain points of industrial applications:

• 全温域稳定ESR<12mω<>：这意味着从寒冷环境到高温满负荷运行，电容器的内阻波动极小，能为电路提供始终如一的、强劲的瞬态电流响应，这对于处理快速负载变化的数字电路and开关电源至关重要。

• Efficiency Improvement (5G Base Station Power Supply): The overall efficiency of the system is from 89.3% to 91.7%, an increase of 2.4 percentage points. In kilowatt-level power base station power supplies, this is equivalent to significantly reducing energy loss and heat generation, which is of direct value for reducing operating costs (electricity costs) and improving equipment reliability.

• Temperature rise and life improvement (new energy vehicle OBC)：

• The capacitor's own temperature rise is reduced by 18°C: It directly proves its low loss characteristics, and the reduction of temperature rise can greatly delay the drying of the electrolyte and extend the life of the capacitor itself.

• Extends power device life by about 30%: This is a more important system-level benefit. The reduced temperature rise of capacitors improves the local thermal environment and reduces the operating temperature of peripheral critical power devices (such as MOSFETs and IGBTs). According to the "Arrhenius model", the life of semiconductor devices can be roughly doubled for every 10°C reduction in temperature. Therefore, reducing the temperature rise of capacitors by 18°C can significantly improve the reliability of the entire power module, which is of great significance to fields with high reliability requirements such as new energy vehicles.

3. Market and application significance

1. Targeting the high-end market: clearly pointed 5G communication infrastructure and New energy vehicles(OBC on-board charger) These two golden tracks with extremely high requirements for efficiency, power density and reliability show Heyue Electronics' determination to enter the high-end industrial market.

2. Solve industry pain points: Achieving higher efficiency and reliability in a limited space is the continuous goal of power module designers. The HY-LZ series provides strong support for system-level optimization by improving the performance of individual components.

3. Domestic substitution and innovation: In the field of high-end aluminum electrolytic capacitors, Japanese manufacturers have long been dominant. Heyue Electronics launched products with clear performance advantages and data support, which is the core component field in ChinaLocalization substitution and independent innovationAn important development.

summary

The release of the HY-LZ series of Heyue Electronics is not only the launch of a new product, but also the launch of a new productA powerful demonstration of the technical capabilities of domestic high-end aluminum electrolytic capacitors。 It achieves breakthroughs in key performance parameters through solid material and process innovation, and has proven system-level benefits (increased efficiency, reduced temperature rise, and extended life) in the most demanding application scenarios. This indicates that in high-end fields such as 5G, new energy vehicles, and industrial power supplies, domestic capacitor brands are beginning to have the ability to compete with international leading manufacturers and provide high value-added solutions.

In the future, it is worth paying attention to the mass production stability, cost control and performance of this series of products in more application scenarios (such as data center server power supplies, photovoltaic inverters, etc.).
