GRM155R61A102KA01D

The GRM155R61A102KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for use in a wide range of industrial, consumer, and telecommunications applications where reliable energy storage and signal filtering are essential. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics. They function as energy storage devices and are commonly used for decoupling, filtering, coupling, and timing applications across circuit boards. The GRM155R61A102KA01D belongs to Murata's GRM series, which represents a well-established family of general-purpose MLCCs that balance performance, cost-effectiveness, and availability for mainstream industrial applications. The part number itself encodes important design parameters. The "0603" case code indicates this capacitor uses a 0603 surface mount package format (0.063 by 0.031 inches), making it suitable for compact PCB layouts while remaining accessible for automated pick-and-place assembly and manual rework. This package size represents a practical middle ground in component miniaturization—small enough for dense circuit boards but large enough to handle without specialized equipment. This capacitor is typically specified in power supply circuits, where it provides bulk capacitance and noise reduction near voltage regulators and digital logic. It's also commonly found in analog signal conditioning circuits, RF applications, and general-purpose filtering stages. Engineers often select Murata MLCCs for their consistent dielectric performance across temperature ranges and frequency bands, low equivalent series resistance (ESR), and proven reliability in demanding environments. The GRM155R61A102KA01D is particularly valued in applications requiring standardized, off-the-shelf components that don't demand exotic materials or extreme performance specifications. Its widespread adoption across the electronics industry means design engineers can rely on well-documented performance characteristics and assured long-term availability through multiple distribution channels. For engineers designing industrial control systems, consumer electronics, automotive electronics, or telecommunications infrastructure, specifying established Murata MLCC part numbers reduces design risk and simplifies supply chain management. When selecting this exact part versus alternatives, engineers consider Murata's manufacturing quality standards, the proven track record of the GRM series in field applications, and the component's ability to meet standard industrial operating conditions. This capacitor represents a reliable choice for engineers who prioritize dependable performance over specialized high-end characteristics.
