1808SC391KAT1A

The AVX 1808SC391KAT1A is a multilayer ceramic capacitor (MLCC) from AVX's 1808 form factor family, a widely recognized and extensively used series in industrial and commercial electronics applications. This component belongs to the surface-mount technology (SMT) category, featuring the 1808 package size, which provides a compact footprint suitable for space-constrained circuit board layouts while maintaining robust electrical performance characteristics. Multilayer ceramic capacitors like this unit are fundamental passive components found in nearly every modern electronic device and industrial control system. The 1808 package format represents a mid-sized option within the MLCC spectrum, offering engineers a practical balance between component density and handling ease during manufacturing. This particular part is constructed using multiple layers of ceramic dielectric material interleaved with metallic electrodes, a proven manufacturing approach that delivers reliable capacitance in a minimal physical footprint. Engineers typically specify AVX MLCCs in the 1808 package for filtering, decoupling, and coupling applications across power supplies, signal conditioning circuits, communication modules, and industrial instrumentation. The compact SMT package allows for efficient automated assembly on modern production lines, reducing manufacturing costs and improving overall system reliability through fewer solder joints and board space optimization. The 1808 form factor is particularly popular in industrial environments where thermal cycling, vibration, and long-term operational stability are critical concerns. AVX's manufacturing processes are designed to meet demanding reliability standards required in automotive, telecommunications, medical device, and factory automation applications. These capacitors are engineered to function across broad temperature ranges typical of industrial settings, and their construction provides inherent protection against mechanical stress encountered during board assembly and deployment. When selecting this specific part number, engineers benefit from AVX's established reputation for consistency and quality within their MLCC product lines. The standardized 1808 package dimensions ensure compatibility with existing circuit board designs and manufacturing equipment calibrated for this size standard. Additionally, the availability of this part from established industrial distributors provides supply chain reliability, an important consideration for engineers designing equipment intended for long-term production runs. The multilayer ceramic construction of the 1808SC391KAT1A makes it suitable for both AC and DC applications, with the component's performance characteristics well-documented across AVX's extensive technical literature and industry references. Industrial buyers appreciate the predictability and standardization that established MLCC families provide when designing systems requiring long service life and minimal field failure rates.
