GRM155R61A106ME21D

The GRM155R61A106ME21D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to Murata's GRM series, which represents a well-established family of general-purpose ceramic capacitors widely used across industrial, commercial, and consumer electronics applications. MLLCs are fundamental passive components that store and release electrical charge, making them essential for filtering, decoupling, timing circuits, and signal conditioning in virtually every electronic system. The GRM series is specifically designed for applications where reliability, compact size, and cost-effectiveness are important considerations. The part number designation provides clues about its construction and characteristics. The "155" in the part number indicates a 0402 metric package size, which measures approximately 1.0mm × 0.5mm × 0.5mm. This compact footprint makes it ideal for space-constrained applications, from handheld industrial devices to complex control systems and instrumentation where board density is a critical design factor. The small size does not compromise functionality, as modern ceramic capacitor technology delivers excellent performance in minimal physical space. Murata's GRM series capacitors are constructed using advanced multilayer ceramic technology, offering good stability across temperature variations and reliable performance in demanding industrial environments. These capacitors are suitable for use in power supply filtering, EMI suppression, coupling and decoupling applications, and signal path circuits in industrial control systems, test equipment, telecommunications infrastructure, automotive electronics, and renewable energy systems. Engineers specify this exact part when they need a proven, reliable general-purpose capacitor in a very small package with Murata's quality assurance backing. The GRM series has an established track record in production environments, making it a lower-risk choice compared to lesser-known alternatives. Additionally, Murata's extensive global distribution network and consistent manufacturing standards mean that design teams can confidently source this component across multiple production runs without concern for inconsistent performance or obsolescence. The specific combination of package size, manufacturer reputation, and the GRM series' broad compatibility with standard PCB assembly processes makes the GRM155R61A106ME21D an efficient choice for engineers designing systems where component reliability and availability are non-negotiable. Whether designing new equipment or maintaining legacy systems, this capacitor represents a balanced solution for cost-sensitive applications requiring high volume compatibility.
