GRM21BR71E334KA01L

The GRM21BR71E334KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading capacitor producers. This component belongs to Murata's GRM series, which represents a broad family of surface-mount ceramic capacitors widely used across industrial, consumer, and automotive electronics applications. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic device. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit applications. The GRM21BR71E334KA01L features a 1206 package size (imperial designation), which is one of the most commonly used standard surface-mount packages for ceramic capacitors. This size offers a practical balance between component density and ease of handling during manufacturing, making it ideal for high-volume production environments typical in industrial electronics. The part number structure itself reveals key specifications about this capacitor. The designation indicates this is a general-purpose capacitor from Murata's established reliability series, designed for mainstream industrial and commercial applications rather than specialized military or aerospace use. Murata's GRM series capacitors are known for consistent performance, stable capacitance values across temperature ranges, and excellent frequency characteristics suitable for digital and analog circuit applications. Engineers typically specify this exact part number when they require a proven, readily available ceramic capacitor in a standard package with predictable electrical behavior and established supply chain reliability. The 1206 package size is particularly valuable in designs where component placement must be relatively large for manual rework or inspection purposes, or where printed circuit board space constraints are less critical than in ultra-miniaturized consumer devices. Industrial applications for this capacitor include power distribution networks in control systems, signal conditioning circuits in measurement equipment, filtering in motor drives, and decoupling networks in programmable logic controllers. The GRM series' reputation for temperature stability makes these components suitable for environments where thermal cycling or elevated operating temperatures are concerns. When selecting this specific part number, design engineers benefit from Murata's extensive design documentation, established application notes, and the component's proven track record in fielded systems. The standardized 1206 package also ensures compatibility with modern pick-and-place assembly equipment and standard solder reflow processes, reducing manufacturing complexity and cost. For engineers designing industrial equipment requiring dependable passive components with straightforward sourcing and predictable long-term availability, the GRM21BR71E334KA01L represents a practical, well-established choice.
