GRM155R71C473KA01D

The GRM155R71C473KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part represents a mid-range offering within Murata's GRM series, which is widely recognized in industrial and commercial electronics applications for reliable performance and consistent quality. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, used for energy storage, noise filtering, and signal coupling across countless applications. The "155" in the part number indicates a 0402 case size, which is one of the most common surface-mount package formats. This compact footprint makes it ideal for space-constrained designs where board real estate is at a premium, particularly in portable equipment, industrial control systems, and consumer electronics. The GRM series from Murata is engineered for applications requiring stable capacitance across varying operating conditions. These capacitors are commonly found in power supply circuits, signal processing paths, and as decoupling elements near integrated circuits. The robust construction and materials used in Murata's multilayer ceramic technology provide good reliability in both consumer-grade and industrial-duty applications. Engineers typically specify the GRM155R71C473KA01D when they need a cost-effective, proven capacitor solution with the dimensional and electrical characteristics this part offers. The 0402 package size combined with Murata's quality standards makes it suitable for high-volume manufacturing environments where consistent performance and traceability are important. This part is particularly common in applications ranging from telecommunications infrastructure to factory automation systems, HVAC controls, and industrial instrumentation. The X7R dielectric material commonly used in similar GRM series capacitors provides predictable behavior across temperature ranges typical of industrial environments, making it preferred over other ceramic formulations for applications where temperature stability matters. The part's design allows it to handle the thermal cycling and mechanical stresses present in industrial settings without significant capacitance drift. Designers working on next-generation products or replacement designs often specify this exact part number to maintain compatibility with established supply chains and proven board layouts. The widespread availability of the GRM series means engineers can confidently specify these components knowing they'll remain accessible for production runs and future revisions. For applications requiring multilayer ceramic capacitors in the 0402 package with proven field history and industrial-grade reliability, the GRM155R71C473KA01D represents a standard specification that balances performance requirements with practical manufacturing and sourcing considerations.
