1808XA331KAT2A

The 1808XA331KAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established producers of passive electronic components. This part belongs to the 1808 chip package family, which refers to its surface-mount form factor measuring 4.5mm × 3.2mm. Capacitors in this package size represent a widely used middle ground in PCB design, offering sufficient capacitance density while remaining compatible with standard manufacturing equipment and assembly processes. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, used to store and release electrical energy, filter noise, decouple power supplies, and perform timing functions. The 1808 package is particularly common in consumer electronics, industrial control systems, telecommunications equipment, and automotive applications where moderate capacitance values and compact board space are required. The "X" designation in the part number typically indicates temperature stability characteristics suitable for general-purpose applications across standard industrial temperature ranges. The "A" suffix generally denotes AVX's standard reliability and performance classification for commercial and industrial use. This positioning makes the part appropriate for applications that don't require specialized high-reliability screening or extreme environmental performance, helping to balance cost and functionality for the majority of engineering designs. Engineers select specific MLCC part numbers like the 1808XA331KAT2A based on several factors beyond basic package size. The exact capacitance value, voltage rating, dielectric material, and temperature coefficient all influence which component best fits a particular circuit function. Within the 1808 family, manufacturers offer variants optimized for different requirements—some prioritizing high-voltage performance, others maximizing capacitance density, and still others emphasizing low equivalent series resistance for high-frequency applications. AVX's product portfolio in the 1808 package encompasses a broad range of specifications, allowing designers to find close matches for their electrical requirements without oversizing components or accepting unnecessary cost penalties. The widespread adoption of this package size means that engineers typically have multiple sourcing options and can reference established application notes and design guides. For circuit designers working on industrial equipment, power management circuits, signal conditioning, or embedded systems, the 1808 package remains a practical choice where space is moderately constrained but not at a premium. The combination of proven manufacturing processes, broad availability, and established performance history makes MLCCs in this format a reliable specification for many applications.
