Samsung electro-mechanics unveils high-voltage MLCCs for growing EV market

As electric vehicle technology evolves, manufacturers are increasingly adopting higher voltage platforms to enhance performance and efficiency. While earlier EV models operated on 400V systems, the industry is now shifting towards 800V platforms. These higher voltage systems not only support faster charging capabilities but also improve drivetrain efficiency, especially at high torque and speeds.

This transition presents new challenges for key electronic components like onboard chargers (OBCs), motor drive inverters, DC-DC converters, battery management systems (BMS), wireless power transfer systems (WPTs), and various subsystems, all of which require MLCCs capable of handling higher voltage ratings.

Samsung Electro-Mechanics has engineered its latest MLCCs with advanced features to meet these high-voltage requirements. Utilising proprietary ceramic materials, micronisation techniques, and innovative soft termination technology, the new capacitors offer enhanced bending strength and durability in their compact 1812-inch (4.5×3.2mm) size. These enhancements ensure reliable performance in EV components exposed to high voltage and harsh automotive conditions.

Additionally, the new MLCCs are compliant with AEC-Q200, the global standard for stress resistance in passive electronic components used in the automotive sector. They also meet RoHS and REACH standards, and can operate in temperatures up to 125°C.

Mass production of these cutting-edge MLCCs is already in progress, with part numbers CL43B222KJRRP#, CL43B224KHU6PJ#, and CL43B474KEU6PJ#. Samples are available upon request for manufacturers seeking to incorporate high-voltage solutions into their EV designs.
