GRM21A5C2D151JW01D

The GRM21A5C2D151JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for general-purpose filtering, decoupling, and signal coupling applications across a wide range of industrial and consumer electronics. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The GRM21A5C2D151JW01D belongs to Murata's GRM series, which encompasses capacitors optimized for surface-mount assembly on PCBs. The component features a 1206 package size (metric designation 3216), making it suitable for both standard and space-constrained board layouts. This package format is one of the most common in industrial electronics, ensuring compatibility with standard manufacturing equipment and facilitating easy replacement during board rework or repair. The "5C" designation in the part number indicates this capacitor uses X5R dielectric material, a temperature-stable ceramic formulation commonly specified for applications requiring predictable performance across a wide operating temperature range. X5R dielectrics are preferred in industrial applications where environmental conditions vary significantly, such as automotive electronics, telecommunications equipment, and factory automation systems. The capacitor's construction and materials are engineered to minimize capacitance drift and maintain stable electrical characteristics under temperature fluctuations. This part number indicates a 150 nanofarad (151 represents 15×10¹) capacitance value with a 10V rated voltage, making it well-suited for low-voltage digital circuits, gate drive networks, sensor interfaces, and power supply filtering in microcontroller and embedded systems applications. Engineers frequently specify Murata MLCCs in this capacitance range for decoupling power supply pins on integrated circuits, where rapid current transients require stable local charge storage. Engineers select the GRM21A5C2D151JW01D over alternatives based on several factors: Murata's reputation for quality and consistency, the proven reliability of X5R dielectric in demanding environments, the 1206 package's balance between size and handling characteristics, and the part's availability through established supply channels. The component's RoHS compliance and standard lead-free construction make it suitable for modern manufacturing practices and environmental regulations. This capacitor represents a fundamental building block in circuit design, and its widespread use across industrial sectors reflects its proven performance in stringent applications ranging from factory control systems to telecommunications infrastructure.
