First automotive 10 µF, 50 Vdc MLCC in 0805-inch size
Murata Manufacturing has announced that the GCM21BE71H106KE02 multilayer ceramic capacitor (MLCC) has begun mass production. It is the first 0805-inch size (2.0 x 1.25 mm) MLCC to provide a capacitance of 10 µF with a 50 V dc rating and is specifically designed for automotive applications.
This cutting-edge product marks a significant advancement in MLCC design, delivering a smaller 0805-inch package while maintaining capacitance, voltage rating, and reliability.
Improvements in advanced driver-assistance systems (ADAS) and autonomous driving (AD) technologies require deploying more ICs in vehicle systems. This increase in ICs also raises the demand for high-capacitance passive components and creates tighter spatial constraints, as more capacitors need to fit onto increasingly crowded automotive PCBs.
Designed for 12 V automotive power lines, the GCM21BE71H106KE02 capacitor utilises Murata’s proprietary ceramic material and thinning technologies to help engineers save PCB space and reduce the overall capacitor count, resulting in smaller, more efficient, and reliable automotive systems. As the first automotive-specific MLCC to achieve a 10µF capacitance with a 50 Vdc rating in the compact 0805-inch size, the GCM21BE71H106KE02 represents a significant advancement in capacitance efficiency. It offers roughly 2.1 times the capacitance of the previous 4.7 µF, 50 Vdc product, despite sharing the same physical size. Furthermore, compared to the previous 10 µF, 50 Vdc MLCC in the larger 1206-inch size (3.2 x 1.6 mm), the new MLCC occupies approximately 53% less space, providing substantial space savings for automotive applications.
Murata will continue to pursue further miniaturisation and increased capacitance of MLCCs, while expanding its product lineup to meet the evolving needs of the automotive market.
