GRM188C80G475KE19J

The GRM188C80G475KE19J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the leading producers of passive components for electronics. This part belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors designed for use in consumer and industrial electronic equipment. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics. They function as energy storage devices, signal coupling and decoupling elements, and noise filtering components in circuits. The GRM188 designation indicates this capacitor uses a relatively compact 0603 surface-mount package, making it suitable for high-density PCB layouts where space efficiency is critical. This package size strikes a practical balance between miniaturization and ease of assembly and rework, making it popular in both volume production and prototype development. Murata's GRM series capacitors are specified for general industrial and commercial applications, offering reliable performance across typical operating temperature ranges. These capacitors employ ceramic dielectric material, which provides stable electrical characteristics while maintaining a low profile and minimal footprint on printed circuit boards. The "80" in the part number indicates the voltage rating class, while "475K" denotes the capacitance value and its tolerance. The "G" designator reflects the dielectric type and performance class, positioning this part as suitable for mainstream industrial use rather than high-reliability military or aerospace applications. Engineers typically specify this exact part number when they require a capacitor that meets specific size constraints, voltage requirements, and capacitance values for decoupling power supplies, filtering high-frequency signals, or coupling AC signals between circuit stages. The 0603 package is particularly favored in compact consumer electronics, IoT devices, telecommunications equipment, and industrial control systems where board real estate must be optimized without sacrificing electrical performance. Alternatives to this specific part might include other capacitors in Murata's GRM family with different voltage ratings or capacitance values, or competing products from manufacturers such as Samsung Electro-Mechanics, TDK, or Kemet. However, engineers choosing this exact part number are typically committing to Murata's manufacturing quality, established supply chain reliability, and the performance characteristics specific to this voltage and capacitance combination. The GRM188C80G475KE19J represents a dependable, standard-performance capacitor suitable for the vast majority of general-purpose industrial and commercial electronic applications requiring compact surface-mount passive components.
