GRM21BC80J106KE19L

The GRM21BC80J106KE19L 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 for delivering reliable performance across consumer, industrial, and automotive applications. Multilayer ceramic capacitors like this model function as energy storage and filtering devices in electronic circuits. They are designed to suppress noise, stabilize voltage levels, block DC while passing AC signals, and couple or decouple signals between circuit stages. The compact form factor and high volumetric efficiency of MLLCs make them ideal for space-constrained applications where board real estate is at a premium. The part number structure provides insight into the component's key characteristics. The "21" in the designation indicates a 0805 metric package size (2.0mm x 1.25mm), a standard surface-mount format that balances ease of handling with integration density. This size is favored in modern electronics manufacturing, compatible with standard pick-and-place equipment and wave or reflow soldering processes. The "BC80" designation refers to the dielectric material composition, specifically a ceramic formulation designed for stable capacitance over temperature and voltage ranges typical of industrial and consumer applications. Murata's GRM series capacitors are engineered for applications requiring consistent electrical performance under varying operational conditions. They are commonly found in power supply circuits, signal conditioning stages, RF filtering applications, and general decoupling roles throughout industrial control systems, telecommunications equipment, medical devices, and automotive electronics. Engineers specify these capacitors in situations where reliability, compact size, and stable performance characteristics are essential requirements. The 0805 package size offers practical advantages for engineers and manufacturers. It provides better mechanical robustness compared to smaller packages, reducing handling damage during assembly while remaining small enough for dense circuit board layouts. The inherent mechanical strength of the ceramic material and Murata's manufacturing quality control make this series suitable for applications subject to thermal cycling, vibration, and humidity exposure. Engineers typically select the GRM21BC80J106KE19L when they need a proven, readily available capacitor that meets established industrial standards and offers predictable performance. The combination of Murata's reputation for quality, the standardized 0805 package compatibility, and the established GRM series track record in demanding applications makes this part a reliable choice for new designs and production builds requiring stable, long-term performance. The component's widespread adoption in industrial electronics means design resources, application notes, and manufacturing support are well-established.
