GRM155R71H471KA01D

The GRM155R71H471KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is designed for general-purpose filtering, decoupling, and signal coupling applications across a wide range of industrial and commercial electronic equipment. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The GRM155R71H471KA01D belongs to Murata's GRM series, which encompasses a broad portfolio of capacitors in various case sizes and electrical ratings suitable for different circuit requirements. This particular part number indicates a 0402 metric case size (1.0mm × 0.5mm), making it ideal for high-density PCB layouts where space is at a premium. The small form factor does not compromise functionality, allowing designers to implement effective filtering and decoupling strategies even in compact devices. Components in this size class are standard in smartphones, tablets, IoT devices, automotive electronics, and industrial control systems where miniaturization is critical. The capacitor is constructed using multiple layers of ceramic dielectric material, which provides excellent capacitance stability and reliable performance across operational temperature ranges typical in commercial and industrial applications. Murata's manufacturing process ensures consistent quality and long-term reliability, making these capacitors suitable for mission-critical applications where component failure can impact system performance or safety. Engineers typically specify this exact part number when their circuit design calls for specific electrical characteristics offered by Murata's GRM series in the 0402 package size. The choice of this particular component over alternatives often depends on matching exact voltage ratings, capacitance values, and dielectric characteristics required by the application. Murata MLCCs are known for maintaining stable performance across temperature variations and under various electrical stress conditions, which is important for reliability-sensitive applications. Applications for this capacitor include power supply decoupling, high-frequency signal coupling, EMI filtering, and voltage smoothing in digital and analog circuits. In industrial settings, these components are found in motor controllers, power management modules, sensor interfaces, and communication equipment. The reliability and performance consistency of Murata components make them a preferred choice for engineers designing systems that must operate reliably over extended periods in demanding environments.
