GRM21BC81H475KE11L

# GRM21BC81H475KE11L MLCC Capacitor The GRM21BC81H475KE11L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive components. This component belongs to Murata's GRM series, a widely-used family of surface-mount ceramic capacitors designed for general-purpose decoupling, filtering, and coupling applications across consumer, industrial, and telecommunications equipment. MLLCs are fundamental building blocks in modern electronics, providing stable capacitance across frequency ranges while occupying minimal board space. The GRM series specifically is engineered for applications requiring reliable performance in compact form factors. These capacitors consist of alternating layers of ceramic dielectric material and precious metal electrodes, which are then sintered together to create a monolithic structure. This design delivers high volumetric efficiency and consistent electrical characteristics. Based on its part number structure, the GRM21BC81H475KE11L features a 1206-equivalent package size (0603 in metric dimensions), making it suitable for dense PCB layouts common in modern consumer electronics, industrial control systems, and telecommunications infrastructure. The compact footprint is particularly valuable in space-constrained applications such as mobile devices, edge computing nodes, IoT sensors, and automotive electronics. This specific part is configured for general-purpose use with a higher capacitance value within the GRM family portfolio. Engineers typically specify parts like this for power supply decoupling near digital logic ICs, analog signal filtering, and coupling applications where cost-effectiveness and reliability are balanced priorities. The X7R temperature coefficient characteristic of many GRM series capacitors makes them suitable for applications where stable performance across operating temperature ranges is important, without the premium cost of NPO/C0G alternatives. Murata MLLCs are recognized in the industry for consistent quality, predictable performance, and long-term availability. This makes the GRM21BC81H475KE11L an appropriate choice for engineers designing products requiring high-volume manufacturing, long production runs, or designs where component obsolescence is a concern. The part's heritage in Murata's established platform means it has been validated across numerous industrial and consumer applications. Whether you're designing power management circuits, signal conditioning boards, or general-purpose filtering networks, this MLCC provides a proven solution that balances performance, size, and cost considerations for mainstream industrial and commercial applications.
