In today's rapidly popularizing intelligent driving, the stable operation of the ADAS domain controller, as the "intelligent brain" of the vehicle, is directly related to driving safety. In the complex automotive power environment, a seemingly tiny capacitor becomes a key component for ensuring system stability and mitigating safety risks. Shanghai Yongming Electronics focuses on the pain points of automotive power supplies, using its self-developed automotive-grade polymer tantalum capacitors to solve ADAS power design challenges and safeguard the intelligent driving functions of new energy vehicles.

Automotive 12V power supply systems often face sudden situations such as voltage fluctuations and instantaneous power outages. Especially when vehicles trigger emergency braking or obstacle avoidance during high-speed navigation assist (NOA) driving, unstable power supply can easily lead to GPU/SoC core data loss, abnormal system shutdown, and even affect critical functions such as steering and braking, failing to meet the highest functional safety level requirements of ASIL-D. At the same time, the space constraints brought about by the high integration of domain controllers and the performance defects of traditional capacitors are long-standing pain points for power supply design engineers.

Current ADAS power supply designs generally face three major challenges: First, limited PCB space necessitates multiple traditional MLCCs connected in parallel to meet power requirements, consuming significant board space and posing substantial challenges for routing and integration. Second, weak power-down protection; traditional aluminum electrolytic capacitors are bulky and have high ESR values, failing to provide effective energy buffering during 12V instantaneous power outages. Third, severe signal interference; MLCCs suffer from piezoelectric whistling and significant capacitance decay due to DC bias, interfering with signal transmission from sensors such as cameras and radar.

Addressing these industry pain points, YMIN Electronics, leveraging its core technologies of high-energy-density sintered tantalum powder and conductive polymer cathodes, has launched the TQD and TQW series of automotive-grade polymer tantalum capacitors. These capacitors achieve performance breakthroughs at both the material and process levels, comprehensively meeting the power supply requirements of ADAS domain controllers.

This product series boasts four core advantages: First, high integration saves space; a single capacitor can replace 6-8 MLCCs, saving over 80% of PCB area and perfectly meeting high-density integration requirements. Second, superior power-down retention provides 7-10ms energy buffer under a 12V power rail, far exceeding the industry standard of 5ms and fully meeting ASIL-D functional safety requirements. Third, ultra-low ESR ensures stable power supply; ESR as low as 50-100mΩ effectively suppresses power ripple and ensures stable power output for GPU/SoC core rails. Fourth, zero whistling and zero capacity attenuation avoid inherent defects of MLCCs, eliminate signal interference, and improve sensor accuracy. Furthermore, the product is AEC-Q200 automotive-grade certified, eliminating the risk of thermal breakdown and combustion, ensuring maximum reliability.

Leveraging its superior performance, YMIN polymer tantalum capacitors have become the preferred solution for ADAS systems, widely adaptable to mainstream application scenarios: In 12V power-down retention scenarios, the TQD42 470µF/16V and TQW42 330µF/25V are recommended, providing reliable power-down protection for core chips; in 48V to 12V step-down output scenarios, the TQD19 10µF/63V and TQD42 33µF/63V are selected, efficiently handling high-voltage step-down ripple and ensuring the quality of the back-end power supply.

Choosing YMIN means choosing triple assurance: First, core technologies are independently controllable, mastering key technologies for tantalum powder and cathode processes, resulting in industry-leading performance; second, stringent automotive-grade certifications, with the entire series meeting AEC-Q200 requirements, reducing the difficulty of system FMEA design; and third, a stable and secure supply chain, mitigating the risks of MLCC supply shortages and price fluctuations, providing a high-quality alternative.
