GRM155R61E474KE01D

The GRM155R61E474KE01D is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across industrial and consumer electronics applications. Multilayer ceramic capacitors (MLCCs) like this component are fundamental building blocks in modern electronics, serving essential functions in power supply circuits, signal coupling and decoupling, filtering, and timing applications. The GRM series specifically is engineered to provide reliable performance across diverse temperature and voltage operating conditions, making these capacitors suitable for demanding industrial environments as well as standard commercial applications. The part number encoding reveals key characteristics: the "155" in the designation indicates a 0402 metric package size (1.0mm x 0.5mm), which is one of the most popular small form factors in modern electronics manufacturing. This compact package enables high-density circuit board layouts, particularly valuable in space-constrained applications such as industrial controllers, power management systems, telecommunications equipment, and portable instrumentation. The "E" in the part number designates the voltage class and dielectric material type used in this capacitor. Murata's GRM series employs Class II dielectric formulations, which offer excellent volumetric efficiency and capacitance density compared to Class I ceramics. This makes them ideal when designers need to achieve specific capacitance values in minimal board space. Engineers typically specify the GRM155R61E474KE01D when they require a cost-effective, reliable capacitor that balances performance across temperature ranges and maintains stable capacitance under varying electrical stress. The 0402 package size is particularly advantageous for automated pick-and-place assembly, reducing manufacturing costs while maintaining high throughput in production environments. This component is commonly found in power distribution networks on microcontroller boards, as decoupling capacitors on analog and digital ICs, in RF and analog signal chains, and in filtering applications throughout industrial equipment. Its proven reliability track record and widespread adoption make it a safe choice for engineers designing systems requiring long-term stability and minimal field failures. When selecting between competing capacitor options, engineers favor this specific part number for applications demanding the combination of small physical size, proven reliability, competitive cost, and performance characteristics that the GRM series consistently delivers across temperature and application variations.
