GRM219R72A103KA01D

The GRM219R72A103KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive components. This capacitor is part of Murata's GRM series, which represents a family of general-purpose ceramic capacitors widely used in electronic equipment across industrial, consumer, telecommunications, and automotive applications. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronic circuits. They serve critical functions including filtering, decoupling, coupling, and bypassing in power supplies, audio circuits, RF applications, and signal processing stages. The compact form factor and reliability of ceramic capacitors make them ideal for high-volume manufacturing and space-constrained designs. The "219" designation in the part number indicates this capacitor uses a 0805 package size, which is a surface-mount form factor measuring 2.0mm by 1.25mm. This size represents a popular middle ground in ceramic capacitor offerings—larger than 0603 packages but smaller than 1206 packages. Engineers often specify 0805 components when they need a balance between component density and ease of assembly and rework in manufacturing environments. The "72A" segment of the part number identifies the dielectric material and voltage class. Murata's ceramic dielectric formulations are designed to meet specific performance requirements, with different classes optimized for either high capacitance density or superior stability across temperature and voltage conditions. This particular variant is suited to general industrial and consumer applications where moderate voltage ratings and reliable performance are required. The "103" element indicates the capacitance value. In standard electronics shorthand, this represents 10 with three additional zeros, translating to 10,000 picofarads or 10 nanofarads, making this a commonly used capacitance value for decoupling, coupling, and filtering applications in audio frequency and RF circuitry. Engineers typically specify the GRM219R72A103KA01D when designing cost-effective, reliable circuits in applications such as consumer electronics, industrial control systems, power management boards, and communication equipment. The combination of Murata's manufacturing quality, the proven GRM series track record, and the practical 0805 package size makes this component a trusted choice for original equipment manufacturers and contract manufacturers alike. For applications requiring specific voltage ratings, temperature stability, or tolerance specifications, consulting the component datasheet and Murata's technical documentation is recommended to ensure this part meets your circuit's exact requirements.
