GRM21BC7YA475ME11K

The GRM21BC7YA475ME11K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part belongs to the GRM series, which represents Murata's general-purpose MLCC line designed for broad industrial and commercial applications. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions in filtering, decoupling, energy storage, and signal coupling across countless applications. The GRM21BC7YA475ME11K specifically features a 1210 package size, which is a standard Surface Mount Device (SMD) footprint measuring 12.0 mm by 10.0 mm. This package size makes it suitable for applications requiring moderate capacitance values where board space is a consideration, but where larger leaded components are not preferred or practical. Based on its part number designation, this capacitor is configured for general industrial use with characteristics typical of the GRM21BC7 series. Parts in this series are commonly specified in power supply filtering, noise suppression, and energy storage applications across industrial control systems, telecommunications equipment, consumer electronics, and automotive electronics. The ceramic dielectric material provides stable performance across a wide temperature range, making these capacitors reliable in environments with moderate thermal variation. Engineers typically specify Murata's GRM series capacitors when they require dependable performance at a reasonable cost point, coupled with excellent availability and proven field reliability. Murata's manufacturing processes ensure consistent electrical characteristics and low defect rates, which are critical considerations in industrial designs where component failure can impact system uptime. The 1210 package size offers a practical balance—it accommodates reasonable capacitance values while remaining compatible with standard PCB assembly processes and not consuming excessive board real estate. This component is frequently used in switching power supplies, DC-DC converters, audio amplifier circuits, and various industrial sensor and control modules. The multilayer ceramic construction provides excellent high-frequency performance characteristics, making it particularly valuable in modern switched-mode power supply designs where rapid charging and discharging cycles occur. For engineers evaluating alternatives, the GRM21BC7YA475ME11K represents a mature, well-characterized solution from an established manufacturer. Murata's extensive product documentation, application notes, and broad market acceptance make this part a low-risk specification choice for designs requiring proven reliability and consistent supply chain availability. The specific combination of package size, dielectric material, and electrical characteristics makes this part number particularly suited to mid-range industrial applications where cost efficiency and performance must be balanced effectively.
