Compact 1.25-kV MLCCs ensure stability
Murata has begun mass production of 1.25‑kV multilayer ceramic capacitors (MLCCs) with a capacitance of 15 nF in a 1210-size (3.2×2.5 mm) package. These MLCCs use a Class 1 ceramic dielectric (C0G, also known as NP0), making them a strong choice for onboard chargers in electric vehicles and power supply circuits in high-performance consumer devices.
Leveraging Murata’s ceramic and electrode materials, along with thin-layer molding and precision stacking technologies, these chip capacitors are optimized for the latest SiC MOSFETs. Thanks to the inherent advantages of C0G per EIA standards—low loss and stable capacitance across a temperature range of -55°C to +125°C—they are suitable for both resonant and snubber circuits.
For added design flexibility, 1.25‑kV MLCCs in the 1210 package are also available in capacitances from 4.7 nF to 12 nF. All of the new devices, including the 15‑nF chip, are offered with tolerances of ±1%, ±2%, and ±5%.
Datasheets for the new high-voltage MLCCs in the 1210 package can be accessed here.
