1808CA221JAT1A

The 1808CA221JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This capacitor features an 1808 package size, which refers to metric dimensions of 18mm by 8mm, making it suitable for applications where moderate component density and reliable performance are required. Multilayer ceramic capacitors like this model are among the most widely used capacitive components in modern electronics. They consist of alternating layers of ceramic dielectric material and metal electrodes, stacked and fired together to create a compact, durable component. This construction method allows manufacturers to achieve relatively high capacitance values in small packages while maintaining good stability across temperature ranges and operating conditions. The "CA" designation in the part number indicates this capacitor belongs to AVX's standard general-purpose ceramic capacitor family, designed for use in a broad range of industrial and commercial applications. These capacitors are typically selected for coupling, decoupling, filtering, and energy storage functions in power supplies, audio equipment, instrumentation, telecommunications hardware, and consumer electronics. The 1808 package size positions this component in the mid-range category, offering a practical balance between capacitance handling capability and board real estate efficiency. Engineers commonly specify ceramic capacitors in this family for applications requiring stable operation over extended temperature ranges and good frequency response. The inherent low ESR (equivalent series resistance) of multilayer ceramic construction makes these capacitors particularly valuable in high-frequency circuits and power distribution networks where rapid charge and discharge cycles are necessary. The robust ceramic dielectric also provides good voltage handling and reliability in demanding industrial environments. The specific capacitance value of this part would typically be found in the part number itself, though the exact marking may require reference to AVX's documentation. When comparing alternatives, engineers evaluate factors including the dielectric system used, voltage rating, temperature coefficient, and tolerance specifications to ensure optimal performance for their specific circuit requirements. For industrial buyers and design engineers, MLCCs in the 1808 package represent a cost-effective solution that combines proven reliability with consistent electrical performance. The widespread availability and established supply chain for AVX components in this category make them a practical choice for both prototype development and high-volume production scenarios where component standardization and long-term sourcing stability are important considerations.
