GRM31BR72J102KW01L

The GRM31BR72J102KW01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading capacitor producers. This component belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications, and automotive applications. Multilayer ceramic capacitors are fundamental passive components found in virtually every modern electronic circuit. They function as energy storage devices, signal coupling and decoupling elements, and filtering components. The GRM31BR72J102KW01L is specifically designed for applications requiring reliable capacitance in a compact form factor, making it ideal for space-constrained designs where PCB real estate is premium. This particular part number indicates several important characteristics about the component's design. The "31" in the part designation refers to the 1206 package size (3.2mm × 2.5mm), a standard metric package dimension that offers a balance between compact footprint and ease of hand-assembly and rework. The "BR" designation indicates the capacitor operates with a Class 2 dielectric material, which provides good volumetric efficiency while accepting wider temperature coefficient ranges compared to Class 1 alternatives. This makes it suitable for general-purpose applications where exact capacitance stability across temperature is less critical than cost and size optimization. The "J" in the part code indicates a capacitance tolerance of ±5%, a standard specification for many industrial and consumer applications. This tolerance level is appropriate for coupling, decoupling, filtering, and timing applications where precise capacitance values are not essential to circuit function. Engineers typically specify the GRM31BR72J102KW01L when designing power supply filters, AC coupling networks, EMI suppression circuits, and signal conditioning stages in industrial control systems, audio equipment, computing peripherals, and automotive electronics. The 1206 package size makes it particularly attractive for high-volume manufacturing environments where automated pick-and-place equipment can reliably handle components at production speeds. Murata's GRM series is distinguished by consistent quality, wide availability through distribution channels, and proven long-term reliability in field applications spanning decades. Engineers select this specific part number when they need a dependable, cost-effective capacitor solution that meets standard industrial specifications without overspecifying performance characteristics or paying for premium materials unnecessary for the application.
