GRM21BR71H184KA01L

The GRM21BR71H184KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, telecommunications, and automotive applications. MLLCs like this component consist of multiple thin layers of ceramic dielectric material interleaved with metal electrodes, all fired together to create a monolithic structure. This construction method allows manufacturers to achieve relatively high capacitance values in compact surface-mount packages, making them ideal for modern printed circuit board designs where space is at a premium. The part designation "GRM21" indicates this is a 1206-size component in the imperial measurement system, which translates to approximately 3.2mm by 2.5mm in metric dimensions. This is one of the most common package sizes for MLLCs, striking a balance between handling ease during automated assembly and space efficiency on circuit boards. The "BR" designation points to this capacitor's X7R temperature coefficient classification, which means it maintains relatively stable capacitance across a wide operating temperature range—a characteristic that makes it suitable for applications experiencing temperature fluctuations. The "71H" portion of the part number indicates the voltage rating. The remaining alphanumeric characters specify the capacitance value, dielectric material properties, and termination finish. Murata's GRM21BR series capacitors with this profile are frequently specified in coupling, decoupling, and filtering applications where moderate voltage ratings and stable temperature performance are required. Engineers typically select this exact part when they need a reliable, proven MLCC with consistent electrical characteristics across production batches. Murata's quality control and extensive application experience make the GRM series a safe choice for designs requiring high reliability. The 1206 package size offers practical advantages during both prototype development and high-volume manufacturing, as it's compatible with standard pick-and-place equipment and manual rework procedures. This capacitor is particularly common in industrial control boards, power supply circuits, and audio equipment where stable performance across temperature variations is important. The combination of proven design, established supply chain presence, and broad application compatibility makes this part number a standard recommendation across many engineering disciplines. Whether designing new equipment or replacing components in existing systems, engineers choose the GRM21BR71H184KA01L for its predictable performance and field-proven reliability in demanding environments.
