1808CC122KAT1A

The 1808CC122KAT1A is a multilayer ceramic capacitor manufactured by AVX, representing a core component used across countless industrial and commercial electronic applications. This capacitor belongs to the 1808 package family, which refers to its surface-mount form factor with dimensions of 1.8mm × 0.8mm, making it suitable for compact, high-density PCB designs where space constraints are critical. Multilayer ceramic capacitors (MLCCs) like this model function as energy storage and filtering elements in circuits. They are engineered to block DC voltage while allowing AC signals to pass, making them essential for power supply filtering, signal coupling, decoupling, and noise suppression applications. The ceramic dielectric construction provides stable performance across various temperature ranges and frequency bands, which is why these components are favored in demanding industrial environments. The "122" designation in the part number indicates the capacitance value in standard electronic notation. AVX's 1808 series capacitors are widely deployed in industrial control systems, telecommunications equipment, automotive electronics, power management circuits, and consumer electronics. Engineers frequently specify components from this family in applications requiring reliable performance under thermal stress, vibration, and environmental variation. What distinguishes a specific part number like the 1808CC122KAT1A is its precise combination of electrical characteristics, including its voltage rating, temperature coefficient class, and tolerance specifications. These parameters determine how the capacitor will perform in a particular circuit design. Engineers select this exact part number when their circuit design requires the particular electrical behavior and reliability metrics that this configuration provides—whether that involves specific voltage handling capability, temperature stability, or performance consistency over the component's operational life. The 1808 package size represents an optimal balance between component miniaturization and manufacturing practicality. It is small enough for modern high-density assemblies yet large enough to maintain reasonable handling and placement tolerances during manufacturing. This makes it economical for high-volume production while remaining practical for specialized industrial applications. AVX, a well-established manufacturer in the passive components industry, maintains strict quality standards for their MLCC products, ensuring consistency and reliability across production batches. The 1808CC122KAT1A is part of a broader ecosystem of capacitor options, but engineers choosing this specific part number have determined it meets their exact circuit requirements in terms of electrical performance, physical constraints, and operational reliability.
