Samsung Electro-Mechanics Develops Two Types of MLCCs for ADAS Essential to Autonomous Vehicles

[Asia Economy Reporter Jeong Hyunjin] Samsung Electro-Mechanics has developed two types of automotive multilayer ceramic capacitors (MLCCs) used in advanced driver-assistance systems (ADAS), an essential safety driving system for autonomous vehicles.

ADAS is a technology that enables vehicles to recognize and judge situations that may occur during autonomous driving and control mechanical devices accordingly. Examples include Lane Keeping Assist System (LKAS), Surround View Monitor (SVM), and Smart Cruise Control (SCC). Autonomous vehicles require stable power supply and noise removal for signals to be transmitted quickly by these semiconductors, necessitating MLCCs that are small in size but have high capacitance.

The MLCCs unveiled by Samsung Electro-Mechanics on the 12th include a small-sized product with a 0603 size (0.6 mm width, 0.3 mm length) and 100 nF (nanofarad) capacitance, and a product with a 3216 size (3.2 mm width, 1.6 mm length) featuring an ultra-high capacitance of 47 μF (microfarad), the highest in the industry.

The 0603 MLCC reduces the area by 64% compared to the existing 1005 size (1.0 mm width, 0.5 mm length) product while maintaining the same capacitance level. Samsung Electro-Mechanics explained that this product is mounted on the signal line inside the automotive electronic control unit (ECU) to remove surrounding noise and accurately transmit signals. At the same time, its bending strength is more than twice the standard to prevent damage from shocks and vibrations during driving. It meets the AEC-Q200 automotive electronic component reliability test standards, making it suitable not only for ADAS but also for automotive body, chassis, and infotainment systems.

The 3216 MLCC has more than twice the capacitance of the existing 22 μF product, achieving the highest capacitance among products of the same size in the industry. Recently, semiconductors in vehicles have become high-performance to process more data quickly as ADAS functions advance, requiring higher power consumption. This product provides stable power supply to in-vehicle semiconductors. Samsung Electro-Mechanics explained that they refined the dielectric ceramic powder, a core material of MLCC, to the nanoscale and applied an ultra-precision layering process. The rated voltage (the maximum voltage the product can withstand without damage) was also increased by 1.5 times to 6.3 V compared to existing products, enhancing durability.

Samsung Electro-Mechanics has recently strengthened its lineup of high value-added automotive products with high temperature, high pressure, and high reliability, and is expanding MLCC supply to global automotive parts manufacturers and automakers. Kim Dooyoung, Vice President and Head of the Component Business Division at Samsung Electro-Mechanics, said, "We will strengthen our technological competitiveness by developing and manufacturing core raw materials for MLCCs in-house, and expand our market share in automotive MLCCs through internalizing facilities and enhancing production capacity."
