GRM31BR72D223KW01L

The GRM31BR72D223KW01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a mainstream offering for general-purpose capacitive filtering and energy storage applications across industrial, consumer, and commercial electronics. Multilayer ceramic capacitors like this component are constructed from alternating layers of ceramic dielectric material and metal electrodes, compressed and fired into a compact monolithic package. The resulting structure provides excellent volumetric efficiency, making MLCCs ideal for space-constrained applications. The GRM31BR72D223KW01L uses a 1206 package format (3.2mm x 1.6mm), a widely standardized surface-mount footprint that facilitates automated assembly and integration into modern PCB designs. This particular part number indicates a capacitor within Murata's mid-range performance tier, suitable for standard industrial and consumer applications rather than specialized high-reliability or high-temperature environments. Engineers typically specify components from this series for decoupling and bypass functions in power supply circuits, noise filtering, signal conditioning, and general energy storage requirements in switching power supplies, audio equipment, automotive subsystems, telecommunications hardware, and industrial control boards. The GRM31BR72D223KW01L's specific designation within the product family suggests it is optimized for voltage and capacitance values commonly encountered in mainstream 3.3V and 5V logic circuits and moderate-voltage analog applications. The 1206 package size represents a practical balance between component density and ease of handling during assembly, making it a cost-effective choice for high-volume manufacturing while remaining accessible for prototype and small-batch development work. Engineers select this exact part variant over alternatives based on several factors: Murata's reputation for consistent quality and reliability, the established supply chain for GRM series components, compatibility with standard automated assembly processes, proven field performance across diverse applications, and the availability of detailed technical documentation and application notes from the manufacturer. The standard 1206 package ensures compatibility with most commercial PCB assembly equipment without requiring specialized tooling or process modifications. The GRM31BR72D223KW01L represents a foundational component in countless electronic systems, functioning as a dependable solution for engineers who require a well-established, cost-effective capacitor with predictable electrical characteristics and broad industry acceptance.
