GRM188C81C475ME11D

The GRM188C81C475ME11D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor belongs to the GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors like this unit are among the most commonly specified passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The GRM188 designation indicates this capacitor uses a 0603 package format (metric equivalent 1608), which measures approximately 1.6mm by 0.8mm. This small surface-mount package allows for high-density circuit board layouts while maintaining robust performance characteristics suitable for both prototype development and high-volume manufacturing environments. The "C81" portion of the part number specifies the component's dielectric material and voltage rating. Murata's GRM series employs X7R or X5R dielectric formulations depending on the specific variant, providing stable capacitance values across a wide operating temperature range—a critical consideration for applications experiencing thermal cycling or extreme environmental conditions. These dielectric types offer better temperature stability compared to Y5V alternatives, making them preferred in precision timing circuits, filtering applications, and temperature-sensitive signal conditioning. Engineers typically select this specific part number when designing circuits that require reliable mid-range capacitance values in applications such as power supply filtering, decoupling networks, AC coupling stages, and EMI suppression. The compact 0603 package strikes an important balance: it occupies minimal board space while remaining large enough to handle adequate current levels and dissipate heat effectively during normal operation. The "ME11D" suffix denotes the specific termination and tape-and-reel packaging format, indicating this component is configured for automated pick-and-place assembly on standard surface-mount production lines. This packaging format has become the industry standard, ensuring compatibility with modern manufacturing equipment and supply chain processes. Murata's manufacturing quality and long-term availability make the GRM188 series a dependable choice for applications requiring components that will remain in production and accessible for extended product lifecycles. Engineers and procurement professionals often standardize on these capacitors across multiple product designs to simplify inventory management and reduce qualification complexity. Whether for consumer devices, industrial control systems, or automotive electronics, the GRM188C81C475ME11D represents a mature, well-established solution for general-purpose capacitive filtering and coupling requirements.
