South Korean electronic component company Samsung Electro-Mechanics has expanded its range of automotive high-voltage multilayer ceramic capacitor (MLCC) products to support larger sizes.

The trend towards using higher voltages in EV power electronic components, including onboard chargers, motor drive inverters, DC-DC converters, wireless power transfer systems, battery management systems, compressors and pumps is increasing demand for high-voltage MLCCs.

To address these requirements, Samsung Electro-Mechanics has started mass production of its CL43B222KJRRPJ#, CL43B224KHU6PJ#, CL43B474KEU6PJ# models. The company has improved the bending strength in the large 1812-inch (4.5×3.2 mm) format by using proprietary ceramics, micronizing materials and soft termination technologies. This extends the company’s product coverage from the existing 1210-inch size.

The X7R dielectric (-55° C to 125° C) MLCCs offer a rated voltage range of 250 V ~ 2,000 V and a capacitance range of 2.2 nF ~ 470 nF.
