GRM188R72A472KA01D

The GRM188R72A472KA01D is a ceramic multilayer chip capacitor manufactured by Murata, one of the world's leading producers of passive electronic components. This compact surface-mount capacitor belongs to Murata's GRM series, which is widely recognized in the electronics industry for consistent quality and reliable performance across diverse applications. Ceramic chip capacitors like this component are fundamental building blocks in modern electronic circuits, serving critical functions in filtering, coupling, decoupling, and energy storage applications. The GRM188 designation indicates a 0603 package size (1.6mm × 0.8mm), making it ideal for space-constrained designs where board real estate is at a premium. This compact footprint has made the GRM188 series a standard choice in consumer electronics, telecommunications equipment, automotive systems, and industrial control boards. The "72A" portion of the part number refers to the dielectric material type used in this capacitor's construction. Murata's X7R dielectric materials are known for maintaining relatively stable capacitance values across a wide temperature operating range, typically performing reliably in environments from -55°C to +125°C. This temperature stability is particularly important for applications where circuit performance must remain consistent despite fluctuating ambient or operational conditions, such as outdoor industrial equipment or automotive under-hood installations. The "472" specification indicates a 4.7 microfarad (µF) capacitance value, a middle-ground capacity rating suitable for general-purpose decoupling and filtering tasks in digital circuits, power management modules, and analog signal conditioning stages. This capacitance value is commonly encountered in applications requiring moderate energy storage or filtering without the size penalty of larger ceramic capacitors. Engineers typically specify the GRM188R72A472KA01D when they require a proven, off-the-shelf ceramic capacitor that balances size, cost, and performance. The Murata manufacturing pedigree ensures consistent quality and availability through established distribution channels worldwide. Designers often select this specific part when existing board designs or qualification processes already incorporate GRM188-series capacitors, minimizing redesign risk and simplifying component procurement. The ceramic construction provides inherent advantages including high volumetric efficiency, excellent frequency response, and low equivalent series resistance compared to older electrolytic alternatives. These characteristics make ceramic capacitors the preferred choice for modern digital circuits, power supplies, and RF applications where performance and reliability are non-negotiable. Whether you're designing consumer electronics, industrial automation systems, or telecommunications infrastructure, the GRM188R72A472KA01D represents a dependable, compact capacitor solution with proven field performance across countless applications.
