1808CC393KAT1A

The 1808CC393KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 1808 package family, which uses a rectangular surface-mount form factor measuring 4.5mm x 3.2mm. This compact size makes it ideal for space-constrained applications while maintaining reliable electrical performance. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling across countless industrial and consumer applications. The 1808 package size represents a popular mid-range option that balances component density with ease of assembly and handling in manufacturing environments. AVX's ceramic capacitor lines are widely recognized in engineering circles for consistent quality and reliable performance across temperature and voltage ranges. The specific designation "393" in the part number indicates the capacitance value and tolerance, following standard electronic component naming conventions. Capacitors in this series are typically employed in power supply circuits, signal conditioning, noise filtering, and voltage regulation applications. Engineers frequently specify AVX ceramic capacitors in industrial control systems, telecommunications equipment, automotive electronics, test and measurement instruments, and various embedded systems where compact, cost-effective passive components are required. A key advantage of selecting this exact part is AVX's manufacturing consistency and traceability, which matters significantly in mission-critical or regulated applications. Engineers designing medical devices, industrial automation systems, or telecommunications infrastructure often prefer established suppliers and known part families rather than unfamiliar alternatives. The 1808 case size offers a practical sweet spot—larger packages than 0603 or 0805 formats provide better current handling and thermal characteristics, yet remain significantly smaller than through-hole or larger surface-mount alternatives, making assembly efficient on modern production lines. AVX's multilayer ceramic capacitors in the 1808 package are constructed using multiple layers of ceramic material with internal electrodes, creating high capacitance density in a small footprint. This design allows for stable performance across typical operating conditions encountered in industrial and commercial equipment. Designers considering this part should verify compatibility with their specific circuit requirements, including voltage rating, tolerance class, and temperature coefficient specifications. For applications requiring detailed electrical or environmental performance data, the manufacturer's technical documentation should be consulted during the design phase to ensure optimal component selection and circuit reliability.
