GRM21A5C2D100JW01D

The GRM21A5C2D100JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This is a general-purpose capacitor designed for broad use across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. Multilayer ceramic capacitors like this part are fundamental passive components used to filter, couple, bypass, and decouple signals in electronic circuits. They provide stable capacitance across a wide range of operating conditions and are valued for their compact size, reliability, and cost-effectiveness. The GRM21A5C2D100JW01D belongs to Murata's GRM series, which is recognized throughout the electronics industry for consistent quality and performance in standard applications. The part number itself contains encoded information about its specifications. The "21" in the designation indicates a 0805 metric package size (2.0mm × 1.25mm), a widely used surface-mount form factor that balances ease of handling with space efficiency on modern PCBs. This compact package makes it suitable for densely populated circuit boards where space is at a premium. The "A" denotes the tolerance class, while the "5C" identifies the dielectric material type, which determines the capacitor's temperature stability characteristics and voltage rating. The "100J" portion specifies the capacitance value and tolerance band. Engineers specify Murata MLCCs like this model for several reasons. Murata maintains exceptionally tight quality controls and consistent component behavior across production batches, which is critical in manufacturing environments where reliability and predictability are essential. The GRM series offers excellent high-frequency performance with low equivalent series resistance (ESR) and inductance (ESL), making these capacitors suitable for applications requiring signal integrity. Additionally, these capacitors demonstrate stable performance across industrial temperature ranges, which is essential for equipment operating in variable environments. The 0805 package size is a standard footprint in the industry, ensuring compatibility with commonly used PCB assembly equipment and design patterns. This standardization reduces design complexity and manufacturing costs compared to less common package types. The part is equally at home in straightforward DC blocking and coupling applications as it is in more demanding filtering circuits in switched-mode power supplies or high-speed digital circuits. For design engineers working on product development, maintenance, or repair documentation, the GRM21A5C2D100JW01D represents a reliable, readily-available choice for general-purpose capacitance needs where the specified electrical characteristics align with circuit requirements.
