GRM155R61A104KA01D

The GRM155R61A104KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This particular part belongs to Murata's GRM series, a family of general-purpose ceramic capacitors widely used across consumer, industrial, and automotive electronics. Multilayer ceramic capacitors are fundamental passive components found in nearly every modern electronic circuit. They serve critical functions including energy storage, signal coupling, noise filtering, and voltage smoothing in power supply circuits. The GRM155 designation indicates this capacitor uses a 0402 metric package size (1.0mm × 0.5mm), making it suitable for compact, space-constrained applications where miniaturization is essential without sacrificing reliability. The "R61" designation within the part number refers to the specific dielectric material system used in this capacitor. Murata's R61 formulation is a mid-range dielectric type optimized for a balance between capacitance stability, voltage handling, and cost-effectiveness. This makes the GRM155R61A104KA01D particularly well-suited for general-purpose applications where tight capacitance tolerance and stable performance across operating temperature ranges are required, but extreme performance specifications are not critical. Engineers specify this exact part number in applications requiring reliable, proven performance in mass-produced electronic devices. Common end-use segments include telecommunications equipment, computer motherboards and peripherals, industrial control systems, and consumer electronics where cost efficiency and proven reliability are priorities. The 0402 package size is especially prevalent in modern portable devices and space-limited applications where circuit density is a key design consideration. The GRM155 series has become an industry standard, which means extensive design history, proven long-term reliability data, and wide availability across multiple distributors. This standardization reduces design risk and simplifies procurement for manufacturers running high-volume production. Engineers working with legacy designs or requiring compatibility with existing circuit layouts frequently specify Murata GRM series capacitors due to their consistent pin configurations and performance characteristics across product generations. For applications requiring precise specification details such as exact capacitance value, voltage rating, temperature coefficient, and tolerance class, the full part number should be cross-referenced with manufacturer documentation. The complete alphanumeric designation encodes all of these critical parameters in a standardized format. This component represents Murata's commitment to providing dependable passive components that form the foundation of reliable electronic systems across diverse industrial and consumer applications worldwide.
