GRM155R61A224KE19J

The GRM155R61A224KE19J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to the GRM series, which is widely recognized across industrial and consumer electronics applications for reliable performance and consistent quality. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronic circuits. They serve critical functions including energy storage, signal filtering, noise decoupling, and voltage smoothing in power distribution networks. The GRM series is particularly popular in applications requiring compact form factors without compromising electrical performance. The "155" designation in the part number indicates this capacitor uses a 1206 package size (imperial notation), making it a surface-mount device suitable for automated assembly on printed circuit boards. This package size represents a balance between component density and ease of handling during manufacturing, making it ideal for space-constrained designs while remaining compatible with standard pick-and-place equipment. The compact footprint allows engineers to maximize board real estate efficiency without sacrificing the circuit's electrical requirements. Murata's GRM series capacitors are engineered for applications spanning automotive electronics, telecommunications infrastructure, industrial control systems, power supplies, and consumer electronics. They are particularly valued in applications requiring long-term reliability, stable performance across temperature variations, and resistance to mechanical stress during assembly and operation. The specific variant indicated by "KE19" suggests this part operates within a defined voltage and temperature coefficient class, designed to maintain stable capacitance across typical industrial operating ranges. This stability makes such capacitors suitable for circuits where capacitance drift could impact performance, such as precision timing circuits, filter networks, and coupling/decoupling applications. Engineers often specify Murata GRM series capacitors when they require components that combine proven reliability, wide availability, and consistent performance characteristics across production runs. The GRM155R61A224KE19J specifically would be selected when the circuit design calls for a particular combination of capacitance value, voltage rating, and temperature stability that this exact part number provides. Murata's extensive documentation, established supply chain presence, and track record of quality make this series a standard choice for design engineers seeking dependable passive components. Whether supporting high-frequency filtering, decoupling in power-sensitive circuits, or general-purpose energy storage, this multilayer ceramic capacitor represents a mature, thoroughly proven solution in the passive components market.
