Key Specifications

The CGA3E2X8R2A103M080AA boasts several key specifications that underscore its suitability for high-performance applications. Its ‘Automotive Grade’ designation, coupled with ‘AEC-Q200’ qualification, signifies that it has undergone rigorous testing to meet the strict reliability requirements of the automotive industry. The ‘Tolerance’ of ±20% indicates the permissible variation in its nominal capacitance value, which is 10nF (nanofarads). This capacitance value is crucial for determining how much charge the capacitor can store. The ‘L x W Size’ of 1.6mm x 0.8mm, corresponding to the EIA 0603 package, denotes its compact surface-mount form factor, enabling space-saving designs in modern electronic assemblies. The ‘T(Max.) / mm’ of 0.9mm specifies its maximum thickness, an important parameter for board layout and component clearance. The ‘Temp. Chara.’ of X8R is a critical attribute, indicating its temperature coefficient of capacitance. X8R capacitors are known for their stable capacitance change of ‘±15%’ over a wide ‘Operating Temp. Range’ from -55°C to 150°C, making them suitable for applications exposed to extreme thermal conditions. The ‘Rated Voltage [DC] / V’ of 100V specifies the maximum DC voltage that can be continuously applied across the capacitor without risk of breakdown, ensuring robust operation in higher voltage circuits. Finally, its ‘Product Status’ as ‘Production’ confirms its active manufacturing and availability for new designs and mass production.
