I. Industry Background: Intelligent Driving Enters Mass Production Phase, Core Competition Lies in Comprehensive Supply Chain Reliability

China's intelligent driving industry has moved beyond the functional testing phase and fully entered a new era of large-scale mass production. For OEMs and automotive Tier 1 suppliers, the stable deployment and economical installation of L3/L4 level LiDAR systems no longer solely rely on product performance parameters. The core factor is the long-term stability of upstream basic components under the harsh conditions of automotive applications, as well as the overall total cost of ownership (TCO). As a leading domestic manufacturer of hybrid solid-liquid capacitors, YMIN Electronics, with its mature products and technological strength, has laid a solid foundation for the large-scale development of the intelligent driving industry.

II. Core Challenges in Mass Production of Automotive LiDAR & Core Demands of Tier 1 Customers

Based on our extensive experience collaborating with multiple automakers and LiDAR Tier 1 suppliers, we have identified significant shortcomings in the long-term stability of traditional MLCC solutions in LiDAR applications. These shortcomings have led to three core concerns among customers:

**Vehicle Safety and Brand Reputation:** MLCCs, due to the piezoelectric effect, experience internal stress. Under prolonged vibration and alternating high and low temperatures, their performance is prone to degradation, interfering with the stability of LiDAR detection response. Any issues with the perception system directly impact the automaker's brand image.

**Lifecycle Cost Control:** If faulty components reach the end-market, it will incur substantial costs for recalls, repairs, and reputation restoration. From a TCO perspective, the overall cost incurred in the after-sales phase is often several times the cost of component procurement.

**Supply Chain Independence and Project Schedule Assurance:** Long-term reliance on MLCCs not only exposes customers to cost pressures from price fluctuations but also exposes them to project delays due to supply chain uncertainties, directly disrupting new vehicle launch plans.

III. Technical Principle Analysis & Inherent Defects of Traditional MLCC Solutions

From a physical perspective, MLCCs use ceramic as the dielectric material. In an alternating electric field environment, they exhibit an inverse piezoelectric effect, causing mechanical deformation. LiDAR operates in a long-term environment of high-frequency vibration and fluctuating temperatures. This continuous mechanical deformation can cause micro-cracks within the device, ultimately leading to problems such as decreased capacitance and increased leakage current.

This defect is a structural issue inherent to the ceramic dielectric itself, and cannot be completely eliminated even by changing brands or optimizing production processes. Therefore, selecting alternative components using entirely new technologies is the fundamental solution to this problem.

Business and Strategic Aspects (In-depth TCO Interpretation)

Procurement Dimension: Product pricing is competitive in the market, and high reliability significantly reduces after-sales risks throughout the product lifecycle. Total lifecycle cost (TCO) encompasses four main components: procurement, operation and maintenance, repairs, and brand damage. YMIN's solutions can significantly reduce the latter three types of hidden costs.

Operational Dimension: Reduces enterprise reliance on MLCCs, mitigates supply chain risks, and ensures stable mass production and on-time delivery. Product lifespan complies with L3/L4 high-end intelligent driving automotive device specifications, helping customers build a long-term competitive advantage in the industry.

R&D Dimension: Stable device performance, ample supply, and high standardization help R&D teams streamline basic adaptation work, focusing on product function iteration and technological innovation.

Economic Analysis of YMIN's Solutions from a TCO Perspective

Product selection should not only compare single purchase prices but also consider the overall lifecycle cost. YMIN's solutions, with controllable and transparent device procurement costs, hedge against unknown after-sales risks and brand damage. From an overall TCO perspective, it is a more cost-effective and better-performing choice.
