1808SC222KAT1A

The 1808SC222KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized producer of passive electronic components. This component belongs to the 1808 package family, which denotes its physical dimensions in metric notation (approximately 4.5mm x 2.0mm), making it a surface-mount device suitable for modern PCB assembly processes. Multilayer ceramic capacitors like this unit are fundamental building blocks in electronic circuit design, serving multiple critical functions including energy storage, filtering, decoupling, and signal coupling across a broad spectrum of applications. The ceramic dielectric material provides stable performance and reliable capacitance retention across typical operating conditions. The "SC" designation within the part number indicates this capacitor belongs to AVX's standard ceramic capacitor series, commonly employed in general-purpose industrial and commercial electronics. These components are frequently specified in power supply circuits, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and consumer electronics where reliable, cost-effective capacitance is required. Engineers select the 1808 package size as a practical middle ground in surface-mount capacitor options. It offers sufficient physical size for reasonable capacitance values while maintaining compatibility with automated manufacturing processes and standard PCB layouts. This package density supports both high-volume production and specialized applications where space efficiency matters but extreme miniaturization is not the primary constraint. The 1808SC series from AVX represents a mature, well-established product line with extensive field history. This proven track record makes these capacitors attractive for applications where component reliability and predictable long-term performance are essential. Original equipment manufacturers and contract manufacturers alike rely on this series for designs requiring stable capacitive performance without exotic specifications. Typical reasons an engineer might specify this exact part include established design precedent, known compatibility with existing manufacturing processes, proven performance in field applications, and favorable cost-to-performance ratio. The 1808 package also provides reasonable accessibility for rework and repair operations when necessary during manufacturing or field service. Industries deploying these capacitors range from telecommunications and data center infrastructure to industrial automation, HVAC systems, power conversion equipment, and embedded computing applications. The component's versatility and established supply chain make it a practical choice for both new product development and legacy system support or component replacement. For detailed electrical specifications, operating ranges, and application guidance specific to your circuit requirements, consulting the manufacturer's technical documentation is recommended to ensure optimal component selection for your design parameters.
