GRM21A5C2E470JW01D

The GRM21A5C2E470JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This specific part belongs to Murata's GRM series, which is widely recognized in industrial and consumer electronics applications for delivering reliable performance in compact form factors. This capacitor is housed in a 1206 package (metric 3216), making it a surface-mount component suitable for automated assembly processes. The compact size allows engineers to integrate multiple capacitors into space-constrained circuit designs while maintaining electrical performance. The 1206 package has become a standard footprint across the electronics industry, simplifying procurement and reducing design complexity for manufacturers. The alphanumeric designation indicates this is a general-purpose MLCC with characteristics suited to broad industrial applications. Multilayer ceramic capacitors like this one are essential in modern electronics, functioning as energy storage elements, noise filtering components, coupling/decoupling circuits, and frequency compensation elements. They appear in power supply circuits, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and countless consumer devices. Murata's GRM series capacitors are engineered for applications requiring stable performance across operating temperature ranges typical of industrial environments. These components are designed to withstand the thermal cycling, vibration, and electrical stress common in manufacturing equipment, test instruments, power conversion circuits, and embedded systems. The ceramic dielectric material provides excellent frequency stability and low equivalent series resistance, which is particularly valuable in high-frequency filtering applications and power distribution networks. Engineers typically specify Murata MLCCs over competing alternatives when application requirements demand proven reliability, consistent performance, and design flexibility. Murata's extensive qualification testing, adherence to international standards, and broad range of capacitance values and voltage ratings make their products suitable for both consumer-grade and mission-critical applications. The GRM series specifically balances cost-effectiveness with performance, making it a popular choice for design engineers managing budget constraints without compromising reliability. The 1206 package size represents an optimal balance for many engineers—larger than smaller packages like 0603, offering better mechanical strength and easier hand handling during prototyping, yet still compact enough for high-density PCB layouts. This combination of proven manufacturer reputation, established package standard, and versatile electrical characteristics makes the GRM21A5C2E470JW01D a practical choice for applications requiring dependable capacitance in a miniaturized format.
