1808WC222KAT1A

The 1808WC222KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, representing a reliable component widely used in industrial electronics and consumer applications. This part belongs to AVX's established line of general-purpose capacitors designed for flexibility across diverse circuit designs and manufacturing environments. The "1808" designation refers to the component's physical package size, indicating a surface-mount rectangular form factor measuring 4.5mm by 2.0mm with a height suitable for standard PCB assembly processes. This compact package allows for efficient use of board space, particularly valuable in applications where real estate is limited or where designers need to achieve higher component density without sacrificing performance or reliability. As a ceramic capacitor, this component offers several advantages that make it attractive to design engineers. Ceramic capacitors provide excellent frequency response characteristics, stable performance across operating temperature ranges typical in industrial settings, and inherent reliability through simple construction without electrolyte that can degrade over time. The MLCC construction ensures low equivalent series resistance (ESR) and equivalent series inductance (ESL), making these capacitors suitable for high-frequency applications, power supply filtering, and signal coupling/decoupling throughout a circuit. The specific part designation suggests this capacitor falls within AVX's mainstream product families intended for general industrial applications rather than specialized high-reliability or military-grade segments. This positioning makes it particularly cost-effective for volume production runs while maintaining performance standards appropriate for standard commercial and industrial electronics. Common applications for capacitors of this type and package size include power supply decoupling near integrated circuits, input/output filtering in power conversion circuits, signal coupling in audio and RF applications, and general filtering across various industrial control and instrumentation equipment. Engineers frequently specify this class of component in consumer appliances, industrial automation systems, lighting control electronics, and telecommunications infrastructure. Designers typically select this specific part when they require a proven, readily-manufactured component with well-established supply chains and proven field reliability data. The 1808 package size represents an optimal balance between performance and ease of assembly using standard surface-mount equipment found in most electronics manufacturing facilities. For engineers considering alternatives, this component's straightforward ceramic construction and established manufacturing process offer predictability in sourcing and consistent electrical performance compared to some specialized alternatives, making it an economical choice for applications where standard-grade performance metrics are sufficient.
