GRM216C81C105KA12D

The GRM216C81C105KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series family, which is widely recognized in industrial and commercial electronics for reliable performance and consistent quality across demanding applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuits, serving critical roles in filtering, decoupling, energy storage, and signal coupling applications. The GRM216C81C105KA12D features a 1206 package size (metric designation 3216), making it suitable for both surface-mount assembly on standard PCBs and integration into compact electronic designs where space efficiency is important. This package size represents a middle ground between smaller capacitors and larger alternatives, offering practical handling characteristics while maintaining reasonable component density. The part number encoding indicates this capacitor is configured for general-purpose industrial applications. Engineers typically specify components from Murata's GRM series in power supply circuits, where decoupling capacitors help stabilize voltage rails and suppress noise; in signal processing circuits, where they facilitate AC coupling and filtering; and in communication equipment, where reliable capacitive performance under varying temperature and frequency conditions is essential. The series is commonly found in automotive electronics, industrial control systems, telecommunications infrastructure, and consumer electronics requiring long-term reliability. Murata's GRM family capacitors are engineered to maintain stable electrical characteristics across temperature ranges typical in industrial environments. The multilayer construction provides inherent advantages including low equivalent series resistance (ESR) and reliable performance at relatively high frequencies, making these components suitable for modern switching power supplies and high-frequency signal conditioning. One key reason engineers select this specific part number over alternatives relates to Murata's manufacturing consistency and quality assurance. The GRM series maintains tight tolerances and predictable aging characteristics, which is critical in applications where circuit performance must remain stable over product lifetime. Additionally, the 1206 package size offers a well-established supply chain and proven compatibility with standard PCB assembly processes, reducing design risk and procurement complexity. This capacitor is suitable for engineers designing industrial control systems, power management circuits, telecommunications equipment, and other applications requiring dependable passive component performance. The combination of proven reliability, established availability, and verified performance characteristics makes the GRM216C81C105KA12D a practical choice for engineers balancing performance requirements with procurement and assembly considerations.
