GRM219C81C475MA73D

The GRM219C81C475MA73D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a family of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronic circuits. They function as energy storage elements, noise filters, and signal coupling/decoupling components across a broad range of frequencies. The GRM219 designation indicates this is a surface-mount device in a compact package format suitable for automated assembly on printed circuit boards. This packaging makes it ideal for space-constrained applications where board real estate is at a premium. The "C" in the part number references the specific dielectric material composition, which determines the capacitor's electrical characteristics and performance across temperature ranges. Murata's ceramic capacitor formulations are engineered to balance capacitance stability, electrical performance, and cost-effectiveness for mainstream industrial and commercial applications rather than specialized military or high-reliability environments. This component is commonly encountered in power supply circuits, where it helps smooth voltage ripple and stabilize DC rails. It also appears in audio signal paths, RF filtering stages, timing circuits, and general-purpose decoupling applications throughout consumer and industrial electronics. Engineers frequently specify GRM series capacitors in these roles because they offer predictable performance, excellent availability, and consistent quality across large manufacturing runs. When selecting this specific part number, engineers are typically prioritizing compatibility with existing board designs, matching component footprints and electrical requirements established in previous product generations, or adhering to company-approved component lists. The GRM series reputation for reliability and Murata's manufacturing consistency make these capacitors a low-risk specification choice for applications where proven performance is valued over exotic characteristics. The compact surface-mount package facilitates high-density PCB layouts and is compatible with standard pick-and-place assembly equipment. This makes the GRM219C81C475MA73D suitable for high-volume manufacturing environments where automation efficiency and component availability are critical factors. For engineers evaluating this part, typical considerations include verifying that the capacitance value, voltage rating, and temperature characteristics match circuit requirements, confirming package dimensions fit the PCB layout, and ensuring the component's dielectric type meets any specific performance needs in the application. The GRM series' extensive documentation and widespread use in reference designs make it a practical baseline choice for general capacitor selection.
