Electronic component company Samsung Electro-Mechanics is expanding its range of automotive high-voltage multilayer ceramic capacitor (MLCC) products to support larger sizes.
With a trend toward higher-voltage applications in electric vehicles (EVs), high-voltage is being applied to various power electronic components, including:
- Onboard chargers (OBC)
- EV motor drive inverters
- Dc-dc converters
- Wireless power transfer systems (WPT)
- Battery management systems (BMS)
- Compressors
- Pumps
As a result, there’s an increasing demand for high-voltage multilayer ceramic capacitors. In addressing these requirements, Samsung Electro-Mechanics says it has improved the bending strength in larger sizes by using proprietary ceramics, micronizing materials, and leveraging soft termination technologies to meet high-voltage demands. At the same time, it’s enhancing the bending strength in the larger 1812-inch (4.5×3.2mm) format from the existing 1210-inch size.
The company is currently mass-producing the following products: CL43B222KJRRPJ#, CL43B224KHU6PJ#, and CL43B474KEU6PJ#. The X7R dielectric (-55° to 125° C) MLCCs offer a rated voltage range of 250 ~ 2,000 V and a capacitance range of 2.2 ~ 470 nF.
