Samsung Electro-Mechanics have developed the MFC (Molded Frame Capacitor) type CL55C543JI6MPN#, which implements 54 nF at rated voltage 1000V in a 2220 inch (5.70 × 5.50mm) size, C0G (-55 to 125°C).
As power-electronics components/systems in vehicles—such as OBCs, inverters, DC-DC converters, wireless power transfer (WPT), battery management systems (BMS), compressors, and pumps—become more integrated, higher reliability is increasingly required.
Samsung high-voltage MLCCs ensure stable performance in critical circuits such as power conversion, inverters, and battery-management systems, serving as core components that enhance EV safety and efficiency.
Application Example: Automotive (C)LLC DC-DC Converter
Resonant DC-DC converters (C)LLC are being increasingly applied to high-voltage battery charging circuits to address demands including EMI noise reduction, support for high voltages, and efficiency.
Resonant MLCCs should be designed with low ESR to minimize energy loss, maintain a stable performance under high-voltage operating conditions and ensure durability for long-term usage.
The 2220-inch Molded Frame C0G 1000V product provides a stable resonant frequency at high voltage with minimal loss and high reliability. It is a suitable solution for high-voltage battery charging circuits.
