GRM155R61A273KA01D

The GRM155R61A273KA01D 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 applications requiring reliable energy storage, filtering, and signal coupling in compact spaces where board real estate is at a premium. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, used across virtually every industry that designs circuit boards. The GRM155 series is characterized by its compact 0402 package size (1.0mm x 0.5mm), making it ideal for high-density PCB layouts found in smartphones, wearables, IoT devices, automotive electronics, industrial control systems, and consumer appliances. The small form factor allows engineers to maximize functional density while minimizing overall device footprint and weight. This particular part number indicates a capacitor from Murata's general-purpose ceramic capacitor family, suitable for applications where stable performance across standard operating temperature ranges is required. Ceramic capacitors in this series are commonly specified for decoupling and bypass applications near power supply pins of integrated circuits, where they effectively suppress high-frequency noise and voltage transients. They're also used in timing circuits, filtering applications, and general energy storage functions throughout power distribution networks. Engineers typically select Murata's GRM155 series when they need a balance of cost-effectiveness, reliability, and consistent electrical performance in a space-constrained design. The 0402 package size represents an industry standard that's widely available across multiple manufacturers, reducing procurement risk while offering competitive pricing. Murata's manufacturing quality and strict process controls make their MLCCs particularly attractive for demanding applications in automotive, medical, and industrial sectors where component reliability directly impacts system performance and field failure rates. The X7R or similar temperature-stable dielectric materials used in many GRM155 capacitors provide predictable capacitance behavior across operating temperature ranges, making them suitable for applications requiring temperature compensation or stable high-frequency performance. This contrasts with Y5V or Z5U dielectrics, which exhibit greater capacitance variation with temperature and are typically reserved for less critical filtering roles. For engineers designing with tight component placement requirements or working on miniaturized PCBs, this Murata capacitor offers proven reliability combined with the practical advantages of an extremely popular standard package size. Its widespread use in high-volume consumer and industrial products has established extensive design history and application knowledge within the engineering community.
