GRM1555C1H221GA01D

The GRM1555C1H221GA01D is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading specialists in passive electronic components. This capacitor belongs to the GRM series family, which encompasses a broad range of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors (MLCCs) are fundamental building blocks in modern electronic circuits, serving critical functions such as filtering, decoupling, energy storage, and signal coupling. The GRM series represents Murata's mainstream offering for applications where reliable, cost-effective capacitance is required without specialized performance demands. These capacitors are constructed from multiple layers of ceramic material with interspersed electrodes, allowing manufacturers to achieve useful capacitance values in compact physical packages. The "1555" designation in this part number indicates a surface-mount package size of 1.6 mm × 1.6 mm (0402 Imperial), making it suitable for high-density circuit board layouts where space is constrained. This miniature footprint is standard in modern PCB design, enabling compact products in smartphones, wearables, IoT devices, automotive electronics, and industrial control systems. The small package size also facilitates automated assembly processes, reducing manufacturing costs and improving production efficiency. Engineers typically specify Murata's GRM series capacitors when they need dependable performance in standard operating conditions with straightforward design requirements. The series offers broad voltage and capacitance ranges, allowing designers to find appropriate values for virtually any general-purpose application. These capacitors are particularly valued in decoupling applications, where they suppress noise and stabilize power supply voltages across integrated circuits. They are also commonly used in AC signal filtering, timing circuits, and impedance matching networks. The popularity of GRM-series capacitors stems from their combination of proven reliability, availability, and cost-effectiveness. Murata's manufacturing processes ensure consistent quality and long-term performance over the operational lifespan of the equipment. Unlike specialized capacitor types designed for extreme temperatures or high-voltage operation, GRM capacitors are engineered for the mainstream requirements of commercial and light industrial electronics. When selecting a specific part number like the GRM1555C1H221GA01D, engineers should cross-reference the complete technical specifications to confirm voltage rating, capacitance value, tolerance, and temperature coefficient match their circuit requirements. Murata's extensive documentation and application notes support engineers in proper selection and PCB layout considerations for optimal performance in their designs.
