GRM188C81C475KE11J

The GRM188C81C475KE11J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, a leading supplier of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across industrial, consumer, and telecommunications applications. Multilayer ceramic capacitors are among the most commonly used passive components in modern electronics. They store and release electrical energy, filter signals, decouple power supplies, and stabilize voltage in circuits. The GRM series is designed for versatility, offering reliable performance across diverse operating conditions and making these capacitors suitable for cost-sensitive applications where general-purpose performance meets project requirements. The part number designation contains key information about the component's characteristics. The "188" in the part number indicates the package size—specifically 0603 in metric (1.6mm × 0.8mm × 0.8mm)—a standard size that balances compact form factor with ease of assembly on modern circuit boards. This size is particularly popular in space-constrained designs while remaining straightforward to handle with automated pick-and-place equipment. The "C81" notation points to the dielectric material type, which influences the capacitor's temperature stability and performance characteristics. Ceramic capacitors in this family typically experience capacitance variation with temperature, making them suitable for general-purpose applications rather than precision circuits requiring tight tolerance maintenance across temperature ranges. Engineers select the GRM188C81C475KE11J for applications requiring a general-purpose capacitor in a compact surface-mount package. Common uses include power supply filtering on digital logic boards, decoupling in microcontroller circuits, EMI suppression, signal coupling and bypassing, and voltage stabilization in consumer electronics and industrial control systems. The 0603 package size makes this component particularly attractive for high-density PCB designs where board real estate is at a premium. The Murata GRM series has earned widespread adoption due to consistent quality, reliable long-term availability, competitive pricing, and compatibility with standard manufacturing processes. Engineers often specify these capacitors when general performance characteristics meet circuit requirements and when volume-cost efficiency is important. For applications requiring superior temperature stability, lower ESR, or higher voltage ratings, alternative capacitor types or different series may be considered. However, for standard filtering, decoupling, and coupling applications across consumer and industrial electronics, the GRM188C81C475KE11J provides proven, dependable performance in a standard package format that integrates seamlessly into established supply chains.
