GRM21BR71H104KA01K

# Murata GRM21BR71H104KA01K Multilayer Ceramic Capacitor The Murata GRM21BR71H104KA01K is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications in consumer electronics, telecommunications, and industrial control systems. This component belongs to Murata's GRM series, which represents a mainstream offering of surface-mount ceramic capacitors widely adopted across the electronics industry. Multilayer ceramic capacitors function as energy storage and filtering elements in electronic circuits. They suppress noise, stabilize voltage supplies, couple and decouple AC signals, and support signal integrity in high-frequency applications. The GRM series is engineered to provide reliable performance across a broad temperature range, making these capacitors suitable for both commercial and industrial operating environments. This particular part number indicates a 0805 package size, which refers to metric dimensions of approximately 2.0 x 1.25 millimeters. The 0805 package represents a popular mid-range form factor that balances ease of handling and placement with reasonable component density on printed circuit boards. Engineers favor this size for applications where space is moderately constrained but manual rework capability or visual inspection requirements may apply. The designation within the part number suggests this capacitor operates at rated voltages commonly encountered in industrial and consumer equipment. Murata's BR series dielectric formulation provides stability across temperature variations, making it suitable for systems that operate in environments with fluctuating thermal conditions. The GRM21 family generally targets applications requiring capacitance values in the picofarad to microfarad range. An engineer might specify the GRM21BR71H104KA01K over alternatives when design requirements call for a cost-effective, proven component with established supply chain maturity. The 0805 package offers advantages when working with standard assembly equipment and when board real estate permits a slightly larger footprint than ultra-compact alternatives. Additionally, Murata's reputation for manufacturing consistency and quality control makes this series attractive for applications where reliability and predictable performance characteristics are essential. This capacitor is commonly found in power supply filtering stages, high-frequency coupling networks, timing circuits, and EMI suppression applications. Its use spans industrial automation, power management modules, audio equipment, and consumer IoT devices. For engineers developing systems requiring stable, dependable capacitive performance without specialized environmental or performance specifications, the GRM21BR71H104KA01K provides a mainstream, readily-specified solution backed by extensive application experience and established distribution channels.
