1808GC221KAT1A

The 1808GC221KAT1A is a thin-film chip capacitor manufactured by AVX, representing a precision passive component widely used in demanding electronic applications where stable capacitance and low losses are critical requirements. This component belongs to the general family of multilayer ceramic capacitors (MLCCs) designed for high-reliability industrial and military-grade applications. The part number designation indicates a 1808 case size, which refers to the physical dimensions of the component in a surface-mount package format. This compact footprint makes it suitable for modern PCB designs where space efficiency is important while maintaining robust electrical performance. The thin-film construction provides superior frequency stability and reduced dielectric losses compared to standard ceramic capacitor technologies, making this part particularly valuable in applications sensitive to capacitance drift across temperature ranges and operating frequencies. Engineers typically specify AVX components from this product line in applications requiring tight tolerance control and predictable performance over extended operating conditions. Common use cases include RF and microwave circuits, precision analog signal conditioning, timing networks, filter circuits, and decoupling applications in high-frequency environments. The thin-film technology in this series is often preferred for applications where capacitance aging and temperature coefficient stability directly impact circuit performance or where regulatory compliance demands reliable operation over the product's service life. The GC designation within AVX's product nomenclature generally indicates this capacitor is engineered for general commercial through military-grade specifications, positioning it as a versatile choice for applications requiring better performance than standard commercial-grade capacitors but without necessarily requiring the highest specification military variants. This makes it a practical solution for industrial equipment, telecommunications infrastructure, test and measurement instruments, and aerospace applications where performance reliability justifies the additional cost. When selecting this specific part versus alternatives, engineers consider the combination of thin-film technology, established manufacturing heritage from AVX, the standardized 1808 case size compatibility with existing designs, and the proven track record in precision applications. The thin-film construction is particularly advantageous when circuit designs depend on low ESR (equivalent series resistance), low dissipation factor, or minimal capacitance variation across operating conditions. For applications requiring confirmation of exact electrical specifications, operating temperature ranges, voltage ratings, or detailed performance characteristics, consulting the manufacturer's documentation for this specific part number is recommended to ensure proper component selection for your particular circuit requirements.
