1812CC103KAT3A

The 1812CC103KAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose and industrial electronic applications. This component belongs to the established 1812 chip capacitor family, which denotes its physical package size of 1.8mm × 1.2mm — a standard surface-mount dimension widely used across consumer electronics, telecommunications, automotive, and industrial control systems. Multilayer ceramic capacitors like this model serve as fundamental energy storage and filtering elements in modern circuit design. They are used to smooth voltage ripple, decouple power supply lines, filter high-frequency noise, and stabilize signal paths in analog and digital circuits. The 1812 package size offers a practical balance between compact board-level footprint and electrical performance, making it suitable for space-constrained applications where larger through-hole capacitors are impractical. The "CC" designation in AVX's naming convention typically indicates this is a general-purpose ceramic capacitor, rather than a specialized variant optimized for specific temperature ranges or voltage classes. The "103K" portion of the part number references the capacitance value and its tolerance band. This capacitor family is commonly specified in switching power supplies, DC-DC converter circuits, audio amplifiers, sensor signal conditioning, and various industrial measurement and control boards. Engineers select the 1812CC103KAT3A for applications where reliable, cost-effective capacitive filtering is needed at standard voltage levels. Surface-mount MLCCs in this size class are preferred over larger packages when board real estate is limited, yet offer better stability and lower equivalent series resistance compared to smaller 0805 or 0603 alternatives. The ceramic dielectric material provides consistent performance across moderate temperature ranges, making these components suitable for both commercial-grade and industrial environments. AVX's 1812CC series maintains consistent mechanical and electrical characteristics across production runs, providing design engineers with predictable performance and straightforward component substitution when needed. The standardized package dimensions ensure compatibility with automated assembly processes and standard pick-and-place equipment used in modern manufacturing facilities. This capacitor is typically mounted using standard reflow soldering processes, compatible with lead-free solder specifications. Its small size and proven reliability make it a staple choice for engineers designing everything from embedded controllers and IoT devices to industrial automation equipment and distributed power management systems where multiple bypass and filtering capacitors are required.
