GRM21BR72A223MA01L

The GRM21BR72A223MA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive components. This capacitor is part of Murata's GRM series, which represents a widely-used family of general-purpose ceramic capacitors designed for mainstream industrial and consumer electronics applications. Multilayer ceramic capacitors like this unit are fundamental passive components found in virtually every modern electronic device. They serve essential functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization. The GRM series specifically targets applications requiring reliable performance at competitive cost-effectiveness, making these capacitors popular in power management circuits, audio systems, automotive electronics, telecommunications equipment, and industrial control boards. The part number itself encodes critical information about this component. The "GRM21" designation indicates a 0805 metric package size (2.0mm × 1.25mm), which is one of the most common surface-mount capacitor formats in modern PCB design. This compact footprint makes it ideal for space-constrained applications while remaining large enough for reliable soldering and handling in automated assembly processes. The "BR" code identifies the dielectric material composition and electrical characteristics appropriate for general industrial use. The "72A" specification relates to the voltage rating and dielectric system used in this particular variant. Engineers typically specify Murata's GRM series capacitors when they need proven reliability, consistent performance across temperature ranges, and availability from multiple distribution channels worldwide. Murata's quality standards and extensive production capacity make these components suitable for both prototype development and high-volume manufacturing runs. The GRM family offers a broad range of capacitance values and voltage ratings, allowing designers to select the exact component needed for their circuit requirements. This capacitor exhibits the typical characteristics of modern MLCCs, including low equivalent series resistance (ESR), compact dimensions that facilitate high-density PCB layouts, and stable performance across standard industrial temperature ranges. The construction uses multiple layers of ceramic dielectric material with internal metal electrodes, a design that provides excellent volumetric efficiency and cost-effectiveness compared to alternative capacitor technologies. The 0805 package size strikes an optimal balance between handling ease, automated placement compatibility, and space efficiency, making it the preferred choice for cost-sensitive manufacturing environments. Whether used in consumer electronics, industrial instrumentation, or embedded systems, the GRM21BR72A223MA01L represents a standard solution for general-purpose capacitive filtering and energy storage applications where reliability and value converge.
