1808CC473MAT1A

The 1808CC473MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established producers of passive electronic components. This part belongs to the general family of surface-mount ceramic capacitors in the 1808 package size, which is a relatively compact form factor widely used in modern circuit board designs where space efficiency is important. Multilayer ceramic capacitors like this one serve as fundamental building blocks in electronic circuits, providing energy storage, filtering, decoupling, and signal coupling functions. The 1808 package denotes a surface-mount configuration measuring approximately 4.5mm by 2.0mm, making it suitable for automated assembly processes used in volume manufacturing. This package size represents a middle ground between smaller 0603 and 0805 capacitors and larger packages, offering engineers a balance between board space constraints and adequate capacitance values within manageable voltage ratings. The "CC" designation in AVX's naming convention typically indicates a general-purpose multilayer ceramic capacitor series designed for broad industrial and commercial applications. The "473" portion of the part number refers to the capacitance value, which in standard electronic component notation indicates 47 multiplied by 10 to the 3rd power, representing the capacitive value in picofarads. The "MAT1A" suffix provides manufacturing date coding and specific variant information particular to AVX's production tracking. Engineers commonly specify MLCC components like the 1808CC473MAT1A in power supply circuits, where they filter and stabilize voltage rails. They also appear in audio signal paths, RF applications, timing circuits, and digital logic boards where decoupling capacitors are essential for reducing noise and maintaining signal integrity. The 1808 package size makes this part particularly relevant in space-constrained applications where designers need reasonable capacitance values without resorting to larger packages or alternative technologies. The choice of an AVX multilayer ceramic capacitor over alternatives often comes down to reliability requirements, cost optimization, and compatibility with established supply chains. AVX is recognized for consistent quality in MLCC production and maintains widespread availability through distribution networks. Engineers selecting this specific part number would typically have validated it against their circuit requirements regarding voltage rating, capacitance tolerance, temperature stability characteristics, and environmental operating conditions. For industrial and commercial electronics manufacturers, the 1808 package MLCC category represents a mature, well-understood technology with predictable performance and established manufacturing practices, making it a standard choice for production environments where component reliability and supply continuity are critical concerns.
