GRM155R61A474KE15D

The GRM155R61A474KE15D is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, a family of surface-mount ceramic capacitors designed for high-reliability applications across industrial, automotive, telecommunications, and consumer electronics sectors. Multilayer ceramic capacitors (MLCCs) like this component serve as energy storage and filtering elements in electronic circuits. They are essential for decoupling, bypassing, and noise suppression applications. The GRM series is widely recognized for consistent performance and reliability, making these capacitors a preferred choice for engineers designing equipment that must operate in demanding environments or meet strict quality standards. The part number itself encodes important information about this capacitor's characteristics. The "155" in the designation refers to the 0805 package size, indicating a surface-mount device with compact dimensions suitable for modern PCB layouts where space optimization is critical. This small form factor allows for higher component density while maintaining standard soldering compatibility with automated assembly equipment. The GRM155R61A series is designed for general-purpose filtering and decoupling in a wide range of applications. These capacitors are commonly specified in power supply circuits, signal processing chains, and RF applications where stable capacitance and low equivalent series resistance (ESR) are important. Their reliability makes them particularly suitable for equipment used in automotive electronics, industrial control systems, medical devices, and telecommunications infrastructure. Engineers typically choose Murata's GRM series capacitors for several key reasons. First, Murata's manufacturing processes ensure consistent dielectric properties and minimal variation across production batches, which is critical for applications requiring predictable circuit behavior. Second, the GRM series offers excellent temperature stability compared to some alternative capacitor families, making these components suitable for installations in environments with wide temperature fluctuations. Third, Murata components are widely specified in reference designs and industry standards, reducing design risk and simplifying component qualification. The 0805 package size also represents an optimal balance between miniaturization and ease of handling during assembly and repair. This makes the GRM155R61A474KE15D a pragmatic choice for both prototype development and high-volume manufacturing scenarios. For engineers evaluating this component, it represents a reliable, proven solution for capacitive filtering and energy storage in standard industrial and commercial applications where Murata's quality reputation and consistent performance are valued advantages.
