GRM21BE71C475MA12L

The GRM21BE71C475MA12L is a multilayer ceramic capacitor manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part belongs to the GRM series of general-purpose ceramic capacitors, which are widely used in consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors (MLCCs) like this component are essential passive elements in modern circuit design. They function to store and release electrical energy, filter noise, couple and decouple signals, and stabilize voltage supplies across a broad range of electronic systems. The compact size and reliability of ceramic capacitors make them ideal for space-constrained applications where performance and longevity are critical. The part number itself encodes key specifications about this capacitor. The "21" in the designation indicates the physical case size, specifically a 0805 package (2.0 mm × 1.25 mm × 1.25 mm), making it suitable for surface-mount assembly on printed circuit boards. This package size strikes a practical balance between miniaturization and ease of handling during manufacturing. The "MA" suffix identifies this as a commercial-grade component operating across standard industrial temperature ranges, appropriate for most non-extreme applications. What distinguishes the GRM21BE71C475MA12L within Murata's product portfolio is its specific dielectric material and electrical characteristics. The X7R dielectric class, indicated in the part number, provides stable capacitance across a wide temperature range with relatively low distortion, making it suitable for applications requiring consistent performance. This ceramic formulation is more stable than Y5V or Z5U alternatives, though it does offer somewhat lower volumetric efficiency. Engineers typically specify Murata GRM series capacitors for their proven reliability, consistent quality, and wide availability. The company's manufacturing processes and quality control standards mean these components maintain tight tolerances and low defect rates, which is crucial in high-volume production environments and applications where component failure could be costly. Additionally, Murata offers extensive documentation and design resources that simplify integration into complex electronic systems. This multilayer ceramic capacitor is commonly found in power supply circuits, RF filters, signal conditioning stages, and general decoupling applications across consumer and industrial electronics. Its proven track record and availability in global supply chains make it a trusted choice for design engineers and procurement specialists seeking reliable passive component solutions.
