GRM188C81C475KE11D

The GRM188C81C475KE11D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part represents a standard general-purpose capacitor designed for use in a wide range of industrial and commercial electronic applications where reliable energy storage and filtering are essential. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics due to their compact size, low cost, and consistent performance across temperature and frequency ranges. The GRM188 series designation indicates this is a surface-mount component in the 0603 imperial package size (approximately 1.6mm × 0.8mm), making it suitable for high-density circuit board layouts where space constraints are critical. This compact footprint allows design engineers to minimize board area while maintaining necessary filtering and decoupling functionality. This capacitor is typically employed as a decoupling or bypass capacitor in digital and analog circuits, where it suppresses voltage transients and filters high-frequency noise on power supply rails. Common applications include switching power supplies, audio amplification circuits, RF equipment, consumer electronics, telecommunications hardware, and industrial control systems. Engineers often specify multiple MLCCs of varying capacitance values on a single board to achieve effective filtering across a broad frequency spectrum. Murata's GRM188 series is known for stable electrical performance and long-term reliability in demanding environments. These capacitors are designed to meet strict quality standards and demonstrate excellent frequency characteristics, making them particularly valuable in applications requiring consistent performance over extended operational lifespans. The ceramic dielectric material used in these capacitors provides stable capacitance across temperature variations, an important consideration for equipment operating in industrial settings with wide temperature swings. The specific part number designation indicates particular electrical characteristics optimized for general-purpose applications. Engineers might select this exact part number when their circuit design requires a capacitor with the particular electrical properties and performance envelope this device provides. Murata's manufacturing reputation and the widespread design adoption of the GRM188 series also make this part a low-risk specification choice for production designs. Whether you're designing consumer products, industrial equipment, telecommunications infrastructure, or automotive electronics, having reliable general-purpose MLCCs in standard package sizes is fundamental to successful circuit design and long-term product reliability.
