GRM219D80E476ME44D

The GRM219D80E476ME44D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which encompasses a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications, and automotive applications. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronic circuits. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and energy storage in timing circuits. The compact form factor and reliable performance of ceramic capacitors make them ideal for high-density PCB designs where space constraints are a consideration. The part number coding indicates several key characteristics. The GRM219 designation tells us this is a surface-mount device with a 0805 package size (approximately 2.0mm x 1.25mm), making it suitable for automated assembly and fitting into space-constrained applications. The "D" in the part number indicates this capacitor is rated for 80-volt operation, making it appropriate for circuits requiring moderate voltage handling. The "476" segment of the part number denotes a capacitance value in the microfarad range, typical for bulk capacitance applications in power management circuits. Murata's GRM series capacitors are manufactured using advanced dielectric materials and construction techniques that provide excellent stability across temperature ranges and frequency responses. These capacitors are designed to meet demanding industrial and commercial standards, with characteristics such as low equivalent series resistance (ESR) and reliable performance in demanding thermal environments. They are commonly found in switching power supplies, voltage regulators, LCD display controllers, and general filtering applications where cost-effectiveness and reliability must be balanced. Engineers typically specify Murata GRM series capacitors when they require a proven, widely-available component with consistent quality and established supply chains. The extensive documentation and long manufacturing history of this series make it a trusted choice for both prototype development and high-volume production runs. The 0805 package size allows for compatibility with standard pick-and-place equipment, simplifying manufacturing processes and reducing assembly costs. For applications requiring surface-mount capacitors in the 80-volt class with standard capacitance values, the GRM219D80E476ME44D represents a reliable, industry-standard solution that has been validated across countless consumer and industrial designs.
