GRM21BR71A475KA73L

The GRM21BR71A475KA73L 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 designed for consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, serving critical roles in power supply filtering, signal coupling and decoupling, timing circuits, and noise suppression. The GRM21 designation indicates this is a compact surface-mount device in the 0805 package size, making it suitable for high-density PCB layouts where space constraints are a significant design consideration. The 0805 package is one of the most widely used standard sizes in the industry, offering an excellent balance between component size and handling ease during manufacturing. The part number structure reveals key performance characteristics. The "BR" coding and "A" designation suggest this capacitor operates at standard voltage ratings commonly used in general-purpose applications across consumer and industrial electronics. The "475K" segment indicates a capacitance value in the mid-range that makes this component versatile for numerous circuit designs, from power management to signal conditioning applications. The 73L suffix points to Murata's specific termination and packaging specifications. Engineers typically specify the GRM21BR71A475KA73L when they need a reliable, high-volume production-grade capacitor with proven performance across temperature and frequency ranges relevant to standard operating environments. The GRM series is known for consistent quality and tight manufacturing tolerances, which reduce design margin variability and improve overall system reliability. This part is particularly popular in applications where cost efficiency and standardization are important, as the 0805 package and GRM series designation are recognized across supply chains worldwide. The ceramic construction provides several practical advantages: excellent frequency characteristics, minimal parasitic effects, and stable performance across typical industrial temperature ranges. These characteristics make MLCCs in this family suitable for both DC blocking applications and high-frequency signal paths, depending on circuit design requirements. For engineers designing systems that require filtering, decoupling, or energy storage in compact form factors, the GRM21BR71A475KA73L offers a well-established solution with extensive application experience in production environments. The combination of package size, Murata's manufacturing reputation, and the proven GRM series platform makes this part a standard choice for engineers seeking reliable passive component solutions.
