Murata Manufacturing has launched the GCJ21BD72A225KE02, a soft-termination multilayer ceramic capacitor (MLCC) designed for automotive powertrain and safety applications. The new component is the first of its kind to deliver 2.2μF capacitance at 100Vdc in a compact 0805-inch (2.0 × 1.25 mm) package, setting a new benchmark for capacitance density in this category.
As automotive systems continue to evolve with increased electrification, advanced driver-assistance systems (ADAS), autonomous driving technologies, and the adoption of 48V architectures, designers require components that offer high capacitance, high voltage capability, and minimal board space usage. Additionally, automotive environments expose components to vibration and temperature fluctuations that can cause board flexing and reliability issues. Murata’s new MLCC addresses these demands by combining compact size, high performance, and enhanced resistance to mechanical stress.
Built on Murata’s proprietary ceramic material design, including fine particle size and uniformity control, the soft-termination chip MLCC achieves 2.2μF at 100Vdc in the 0805-inch size, a rating previously only possible in the larger 1206-inch (3.2×1.6mm) size. The result is an approximately 51% reduction in board mounting area compared to Murata’s previous 2.2μF/100Vdc offering, and an approximately 2.2x increase in capacitance over its previous 0805-inch, 100Vdc product. Soft termination further enhances field reliability by absorbing board flexure stress and reducing post-mount cracking.
The GCJ21BD72A225KE02 supports an operating temperature range of -55°C to +125°C and meets X7T temperature characteristics per EIA standards.
Murata will continue expanding its automotive grade MLCC lineup, delivering the miniaturization, high capacitance, high voltage ratings, and reliability that next-generation vehicles demand.
