GRM155R61C224KA12

The GRM155R61C224KA12 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 applications in consumer electronics, industrial equipment, and telecommunications devices where reliable energy storage and signal filtering are required. Multilayer ceramic capacitors like this model are constructed from alternating layers of ceramic dielectric material and metal electrodes, all stacked and fired into a single compact component. This construction method allows manufacturers to achieve relatively high capacitance values in a very small physical footprint, making MLCCs essential for modern printed circuit board (PCB) design where space constraints are critical. The part number designation itself provides key information about this capacitor's characteristics. The "155" in the part number indicates a 0805 surface-mount package size (0.08 inches by 0.05 inches), which is one of the most commonly used standard sizes in electronics manufacturing. This compact package allows for high-density PCB layouts while remaining easy to handle during automated assembly processes. The "224" designation refers to the capacitance value, following standard electronic color code conventions. This particular model belongs to Murata's general-purpose ceramic capacitor family, suitable for applications including power supply decoupling, signal coupling and decoupling, noise filtering, and timing circuits. Engineers often specify Murata MLCCs in this size and class for mainstream commercial and industrial products because of their consistent quality, predictable performance, competitive pricing, and broad availability across distribution channels worldwide. Compared to alternative capacitor technologies, MLCCs offer several advantages that make them the default choice for this application class. They provide stable capacitance across a wide operating temperature range, have low equivalent series resistance (ESR), and exhibit minimal leakage current. They are also non-polarized, eliminating installation orientation concerns on the PCB. Their small size and weight make them ideal for portable devices and space-constrained equipment. Murata's reputation for quality control and consistency makes the GRM155R61C224KA12 a reliable choice for engineers designing products requiring long-term reliability and minimal field failures. The widespread use of this type of capacitor in thousands of designs worldwide means extensive design reference materials, application notes, and proven circuit topologies are readily available to development teams.
