GRM1552C1H120GA01D

The GRM1552C1H120GA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for use in a wide range of consumer, industrial, and automotive electronics applications where reliable energy storage and signal filtering are required. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics. They function as energy storage elements, noise filters, and coupling/decoupling components in circuits. The GRM1552C1H120GA01D belongs to Murata's GRM series, which represents a broad family of general-purpose MLCCs engineered for mainstream industrial applications. The part number structure reveals key information about this component's design. The "1552" designation indicates the physical package size, which is a 0402 metric size (approximately 1.0 mm × 0.5 mm). This compact footprint makes it ideal for space-constrained designs in modern electronics where board real estate is at a premium. Despite its small size, the component is engineered to deliver consistent performance in high-volume production environments. The "C1H" portion of the part number identifies this as a capacitor with a Class II dielectric material, which offers a good balance between capacitance density and temperature stability. Class II ceramics are widely used in consumer and industrial applications where moderate capacitance values and cost-effectiveness are priorities. The "120GA01D" suffix indicates the specific capacitance value and construction variant within this family. Engineers typically specify this exact part number when they need a proven, standardized component that has been validated across numerous production runs. Murata's GRM series enjoys broad adoption in the industry, which means design teams can rely on consistent availability, well-documented performance characteristics, and compatibility with established manufacturing processes. The compact 0402 package size appeals particularly to designers working with modern PCB layouts where component density is high. Common application areas for general-purpose MLCCs in this size range include power supply filtering in microcontroller circuits, signal conditioning in sensor interfaces, and EMI suppression in digital communication paths. The reliability and performance consistency of Murata's GRM components make them popular choices in industrial control systems, IoT devices, and consumer electronics where long-term stability is important. For engineers evaluating alternatives, this part represents a balanced choice combining proven reliability, standard sizing, and broad market acceptance. Its specification within the GRM family makes it suitable for both prototype development and volume production scenarios.
