18122C183KAT2A

The 18122C183KAT2A is a multilayer ceramic capacitor manufactured by AVX, one of the industry's established producers of passive electronic components. This component belongs to the broad family of ceramic disc capacitors, which are essential passive elements used across countless electronic applications for energy storage, filtering, and signal coupling. Multilayer ceramic capacitors (MLCCs) like this part are constructed from alternating layers of ceramic dielectric material and metal electrodes, all stacked and fired together to create a compact package. This construction method allows manufacturers to achieve relatively high capacitance values in small physical sizes compared to single-layer designs. The resulting components are rugged, cost-effective, and well-suited to high-volume production environments. This particular part is specified in applications where reliable DC and AC filtering is required, including power supply circuits, signal decoupling, noise suppression, and timing circuits. Engineers frequently encounter these capacitors in consumer electronics, industrial control systems, telecommunications equipment, automotive electronics, and general-purpose PCB designs. The multilayer construction provides stable performance across a wide operating range and offers good frequency response characteristics for filtering applications. The "C183" designation in the part number typically indicates the capacitance value and voltage rating within AVX's naming convention, while the "KAT2A" suffix references the specific package type, lead configuration, and termination style. AVX multilayer ceramic capacitors in this series are commonly found in applications where a balance of performance, size, and cost is prioritized. Key reasons an engineer might select this exact part include its proven reliability in established designs, compatibility with standard automated assembly equipment, widespread availability through multiple distribution channels, and AVX's reputation for consistent manufacturing quality. The specific package configuration also makes it suitable for both through-hole and surface-mount assembly depending on the exact variant and application requirements. When comparing alternatives, engineers consider factors such as temperature stability of the dielectric, equivalent series resistance (ESR), voltage derating characteristics, and long-term aging behavior. AVX capacitors in this series are engineered to meet relevant industry standards and provide predictable performance across temperature and frequency ranges typical for industrial and commercial applications. This component is appropriate for designers working on equipment requiring proven, reliable passive components with established supply chains and technical support resources.
