Samsung Electro-Mechanics announced on the 5th that it has developed a micro-sized high-voltage multilayer ceramic capacitor (MLCC) for the LiDAR system, a key component of autonomous driving.
The newly developed MLCC by Samsung Electro-Mechanics has a size of 1005 (1.0 mm wide and 0.5 mm tall) with a capacity of 2.2 µF (microfarads) and is designed for high voltage at 10V. It has raised the high voltage approximately 60% compared to the existing 6.3V, becoming the world's first to receive AEC-Q200 certification, which is a critical reliability standard for automotive electronics, in the same specifications. It can also be used in various applications, including advanced driver assistance systems (ADAS), body, chassis, and infotainment.
This product is used in the LiDAR system for automobile autonomy, which detects the surrounding environment and supports safe driving through precise distance measurements. A micro-sized, high-capacity MLCC is essential for the LiDAR system to obtain accurate data in millimeter units, ensuring stable power supply and accurate system delivery.
Additionally, due to the characteristics of LiDAR installed outside the vehicle, a high-voltage MLCC with reliability exceeding safety margins of twice the normal is essential to cope with various environmental changes. The new MLCC realizes this need, with Samsung Electro-Mechanics developing unique additives and employing a new technique that minimizes empty spaces within the dielectric to operate stably even at high voltages.
Based on its technology in micro-sized and ultra-high-capacity MLCCs, Samsung Electro-Mechanics is strengthening its lineup of electronic component products such as high-temperature, high-pressure, and high-reliability products while expanding its supply of MLCCs to global automotive parts manufacturers and finished vehicle companies. According to market research firm Mordor Intelligence, the automotive MLCC market is expected to grow significantly from 4.5 trillion won in 2024 to 10 trillion won by 2028.
Choi Jae-youl, vice president and head of the component solution division at Samsung Electro-Mechanics, said, "With the electrification of vehicles, the demand for high-performance and high-reliability MLCCs is increasing, and Samsung Electro-Mechanics aims to strengthen its differentiated technological competitiveness through securing essential technologies for materials, equipment, and methods of MLCCs, actively responding to the market with high-value products."
