Why High-Voltage MLCCs Matter in Modern Power Electronics
As electric vehicles and high-performance consumer electronics adopt silicon carbide (SiC) MOSFETs for higher efficiency and faster switching, the demand for capacitors that withstand elevated voltages and temperature extremes has increased. Resonant and snubber circuits in onboard chargers (OBCs) and advanced power-supply units rely on components that maintain stable characteristics under repeated high-voltage stress. Even minor performance shifts can result in heat buildup, reduced efficiency or premature failure.
Murata addresses this need with the launch and mass production of a 15nF, 1.25kV C0G MLCC in the 3225M (1210-inch) size, designed specifically for high-voltage, high-reliability power conversion.
How the New 1.25kV C0G MLCC Differentiates Itself
Murata’s new MLCC combines high voltage tolerance, low loss, and stable capacitance within a compact footprint, enabling designers to reduce board size while meeting the requirements of fast-switching SiC devices. Where typical high-voltage capacitors increase in size as voltage ratings rise, Murata leverages proprietary ceramic materials, thin-layer moulding and high-precision stacking to deliver 1.25kV performance in a 3.2mm × 2.5mm package.
Its C0G dielectric—aligned with EIA standards—ensures minimal capacitance drift and stable operation from –55°C to +125°C, making it suitable for resonant tanks and snubber networks that experience constant thermal and electrical cycling. The product line spans 4.7nF to 15nF with tight tolerances from ±1% to ±5%, giving designers flexibility in matching component values to switching frequency and circuit topology.
Supporting SiC MOSFET Adoption and High-Reliability Applications
SiC MOSFETs typically operate around 1.2kV, requiring capacitors that exceed this threshold and remain stable during fast switching. The new Murata MLCC is specifically engineered for these conditions, suppressing voltage spikes and improving overall conversion efficiency in OBCs, industrial power modules and high-performance consumer power supplies.
Its combination of compact size and high reliability also allows manufacturers to reduce thermal stress, maintain consistent power delivery and design smaller, more efficient power stages.
Murata’s Commitment to Miniaturisation and Sustainability
The new MLCC reflects Murata’s wider strategy to advance high-voltage ceramic capacitor technology through further miniaturisation, increased capacitance density and higher voltage ratings. Alongside electrical performance, Murata continues to emphasise sustainability by improving material efficiency, reducing waste and integrating recycling processes into MLCC manufacturing.
