'For IT' 100x Voltage 1000·630V Grade Automotive MLCC
Increasing Demand for High-Voltage MLCCs for Electric Vehicle Fast Charging
Following Camera Modules, MLCCs... "Strengthening Automotive Business"
Samsung Electro-Mechanics, which has identified automotive electronics (electric and electronic equipment for vehicles) as one of its core growth engines, has developed a ‘high-voltage multilayer ceramic capacitor (MLCC)’ applicable to electric vehicles and is expanding its product lineup for automotive electronics.

On the 19th, Samsung Electro-Mechanics announced that it has developed five types of automotive MLCCs that can reliably supply power in environments using 630V (volts) or higher, and plans to supply them to global automotive parts customers.
MLCCs are components that control the stable flow of current in electronic device circuits. At least 3,000 to 10,000 are used in a single vehicle.
The automotive MLCCs developed by Samsung Electro-Mechanics have a voltage rating more than 100 times higher than the existing IT MLCC voltage of 6.3V. These are high-difficulty, high-value-added products guaranteed for 630V and 1000V. They are designed to withstand high voltage, thereby enhancing battery stability. The products developed by Samsung Electro-Mechanics are classified into five types according to size and voltage.

The new products will be installed in onboard chargers (OBC), which are key components of electric vehicle charging systems. The onboard charger is a device that receives power from an external charger and charges the battery inside the vehicle. It is one of the core components that determine driving performance and the amount of electricity that can be charged at one time.
Choi Jae-yeol, Vice President and Head of the Component Business Division at Samsung Electro-Mechanics, said, "We have proven our technological capabilities by developing high-voltage MLCCs for automotive electronics. We will enhance our technological competitiveness by developing and manufacturing core raw materials for MLCCs in-house, and increase market share through internalizing equipment and expanding production capacity."
The high-voltage MLCC market for electric vehicles is expected to grow at an average annual rate of about 22%, from $4 billion (approximately 5.3 trillion KRW) this year to about $11 billion (approximately 14.7 trillion KRW) by 2029.
