Murata Manufacturing Co., Ltd. (TOKYO: 6981) has announced the launch and mass production of its 15nF, 1.25kV C0G multilayer ceramic capacitor (MLCC) in the compact 1210-inch (3.2mm x 2.5mm) footprint, marking a first in the industry. The new component is designed to deliver high efficiency and stable performance under demanding high-voltage conditions, particularly in onboard chargers (OBCs) for electric vehicles (EVs) and power supply circuits for high-performance consumer electronics.
Resonant and snubber circuits, which are critical for efficient power conversion and voltage/current peak suppression, increasingly require capacitors that can sustain performance under repeated exposure to high voltage and current. Even minor deviations in capacitance or losses can generate heat, reduce efficiency, or cause system failures. Recent adoption of silicon carbide (SiC) MOSFETs, which support higher switching speeds and improved efficiency, has driven demand for capacitors rated above 1.2kV, with stable performance across broad temperature ranges.
Murata’s new MLCC leverages proprietary ceramic and electrode materials, thin-layer molding, and high-precision stacking technology to meet these requirements. The C0G characteristics, compliant with EIA standards, offer low loss and minimal capacitance variation across temperatures from -55°C to +125°C, making it well-suited for both resonant and snubber circuits. The series also provides design flexibility, with capacitance options ranging from 4.7nF to 15nF and tolerances of ±1% to ±5%.
The company emphasized that the new MLCC supports the latest SiC MOSFET technologies while contributing to efficient power conversion and reliability in high-voltage applications. Murata also reaffirmed its commitment to ongoing miniaturization, higher voltage ratings, and environmental sustainability, focusing on reduced resource use, minimized waste, and recycling in production processes.
