Samsung Electro-Mechanics unveiled a high-voltage and ultra-small multilayer ceramic capacitor (MLCC) in a 1005 size for autonomous driving.
The newly developed MLCC has a capacity of 2.2uF (microfarads) and operates at a high voltage of 10V, with dimensions of 1005 size (1mm x 0.5mm). This high voltage is approximately 60% higher than the previous standard of 6.3V, making it AEC-Q200 qualified, a critical reliability standard for automotive products in this specification.
The product provides suitable performance in LiDAR systems, which are key devices for autonomous driving.
The product (part number CL05Y225KP66PN) is the first 10V, 2.2uF MLCC capacitor available in 1005 size, suitable for supporting stable power supply and accurate signal transmission in various automotive applications.
Generally, it is difficult for MLCCs to satisfy both voltage and capacitance characteristics simultaneously. To achieve high voltage, the dielectric used for storing electricity must be made thicker, which reduces the number of internal dielectric layers that can be stacked, making it difficult to increase capacitance. Samsung Electro-Mechanics has developed proprietary additives and a new manufacturing method that minimizes empty spaces within the dielectric, allowing stable operation even at high voltages.
The newly developed MLCC is suitable for various applications, including Advanced Driver Assistance Systems (ADAS), body, chassis, and infotainment systems.
"The demand for high-performance and high-reliability MLCCs is increasing due to the electrification of vehicles," says Executive Vice President Choi Jeremy, head of Samsung Electro-Mechanics' Component Solution Unit. "We will strengthen our competitive edge in differentiated technology by securing key technologies in materials, equipment, and manufacturing processes for MLCCs, and actively respond to growth markets focusing on high-value products."
