1808SA181KAT1A

The AVX 1808SA181KAT1A is a surface-mount ceramic capacitor designed for general-purpose energy storage, filtering, and signal coupling applications in electronic circuits. This component belongs to the 1808 package family, a standardized rectangular form factor measuring 4.5mm x 3.2mm, which provides a reliable balance between compact size and handling ease in automated assembly processes. Ceramic capacitors of this type are widely used in industrial control systems, telecommunications equipment, power supply circuits, and consumer electronics where consistent performance and cost-effectiveness are priorities. The 1808 package size makes this component particularly suitable for space-constrained designs that still require robust through-hole or surface-mount reliability without requiring the ultra-miniaturization of smaller packages like 0603 or 0402. The "SA" designation within AVX's product naming typically indicates a standard performance class ceramic capacitor, suggesting this part is intended for standard industrial and commercial applications rather than specialized military or high-reliability segments. This positioning makes it appropriate for applications where performance requirements are well-defined but extreme environmental conditions or mission-critical reliability demands are not present. Ceramic capacitors in this package family are valued by design engineers for their stability across operating environments, low equivalent series resistance, and excellent frequency response characteristics. The 1808SA series generally exhibits low parasitic effects, making these components suitable for high-frequency filtering, AC coupling, and bypass applications. Their compact footprint allows circuit designers to achieve effective noise suppression and signal integrity in densely populated PCBs. Engineers commonly specify this exact part number when they have validated the 1808 package size within their manufacturing processes, established relationships with AVX as a supplier, or require compatibility with existing bill-of-materials specifications. The standardized nature of this package also simplifies supply chain management and reduces qualification burden compared to proprietary or less common component families. When selecting between similar alternatives, engineers consider factors including the specific capacitance value, voltage rating, and temperature coefficient of this part relative to their circuit requirements. The AVX 1808SA series represents a well-established product line with consistent manufacturing processes and long-term availability, factors that support reliable production planning in industrial applications. This component is best suited for applications requiring dependable filtering, decoupling, or energy storage where the balance of performance, cost, and size fits the engineering constraints of the design.
