GRM1555C1H100GA01D

The GRM1555C1H100GA01D is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, which comprises general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors (MLCCs) like this model are among the most widely deployed passive components in modern electronics. They function to store electrical charge, filter noise, couple or decouple signals, and stabilize voltage supplies in circuits. The GRM series is known for reliable performance in mainstream applications where cost-effectiveness and consistent quality are essential requirements. The part number structure reveals key characteristics of this component. The "1555" designation indicates the physical package size, specifically a 0402 metric size (1.0mm × 0.5mm), making it suitable for compact, space-constrained designs common in portable devices and miniaturized industrial electronics. The "C1H" portion of the code denotes the electrical characteristics class, which typically indicates this is a general-purpose capacitor with moderate temperature stability suitable for many standard applications. The "100GA01D" suffix provides additional specification information related to the capacitance value, voltage rating, and manufacturing specifications particular to this variant. Murata's GRM series capacitors are manufactured using advanced ceramic dielectric materials and multilayer construction techniques, which enable high volumetric efficiency. These capacitors are designed to meet stringent reliability standards and are widely trusted in applications ranging from power supply decoupling to EMI filtering. Engineers typically specify this particular part when designing circuits that require a compact, cost-effective capacitor with proven long-term reliability. The GRM series is particularly popular in designs where standard industrial-grade performance is sufficient, making it a go-to choice for high-volume production runs. The 0402 package size is especially valuable in modern PCB layouts where board space is at a premium, such as in wearable devices, IoT sensor modules, portable test equipment, and distributed industrial control systems. The robust manufacturing standards associated with Murata's GRM line make this component suitable for both standard operating environments and moderately challenging conditions encountered in industrial settings. Designers often choose this specific part family because the extensive market adoption means proven field reliability data, excellent availability through multiple distribution channels, and compatibility with standard PCB assembly processes. For applications where performance requirements fall within the general-purpose range, this capacitor represents a practical, economical solution backed by manufacturer quality assurance.
