GRM188R61C475KE11J

The GRM188R61C475KE11J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to Murata's GRM series, which represents a comprehensive line of general-purpose ceramic capacitors designed for widespread industrial and commercial applications. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, used to filter, bypass, decouple, and store electrical energy across countless circuit designs. The GRM188 designation indicates this is a relatively compact surface-mount device, making it ideal for space-constrained applications where board real estate is at a premium. The 0603 package size (approximately 1.6mm x 0.8mm) positions this component as a versatile choice for both cost-sensitive consumer products and demanding industrial equipment. The "R61C" portion of the part number reflects the capacitor's dielectric material and voltage rating class. Murata's color-coded designation system helps engineers quickly identify key characteristics without requiring constant datasheet reference. The "475" indicates the nominal capacitance value, while the "K" tolerance marking is standard for general-purpose applications where tight tolerance control is not critical. This combination makes the GRM188R61C475KE11J suitable for applications where moderate capacitance stability and standard performance are sufficient. Engineers typically specify this exact part number in power supply circuits, signal conditioning networks, high-frequency filtering stages, and general PCB decoupling applications. The MLCC technology offers excellent frequency response characteristics, making these capacitors particularly valuable in RF and mixed-signal designs. Compared to tantalum or electrolytic alternatives, MLCCs provide superior high-frequency performance, greater reliability in terms of failure modes, and better resistance to mechanical shock and vibration—critical factors in industrial environments. The GRM series from Murata is widely recognized for consistent quality and proven field reliability across billions of deployed units. Engineers choose specific part numbers like this one based on precise matching of capacitance value, voltage rating, package size, and dielectric stability requirements for their particular circuit topology. The 0603 package strikes an effective balance between handling ease during assembly and space efficiency on modern PCBs. This component is commonly found in consumer electronics, telecommunications equipment, industrial control systems, automotive electronics, and medical devices. Its combination of proven performance, compact form factor, and availability through established distribution channels makes it a preferred specification for design engineers seeking dependable passive component solutions.
