1808HC101KAT1A

# Product Description The 1808HC101KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for use in a wide range of industrial and consumer electronics applications. This component belongs to the 1808 case size family, which refers to its compact surface-mount package dimensions (approximately 4.5mm × 2.0mm). The "HC" designation indicates this is part of AVX's high-capacitance series within their standard MLCC offerings. Multilayer ceramic capacitors like this part are fundamental passive components used extensively in power supply circuits, signal coupling and decoupling applications, filtering stages, and timing circuits. In industrial equipment, they serve critical roles in voltage regulation, noise suppression, and signal integrity management. Engineers commonly specify MLCCs in this package size for applications where space is limited but reasonable capacitance values are still required. The 1808 case size represents a middle ground in the surface-mount capacitor landscape. It offers greater capacitance density than smaller packages like 0805 or 1206, while maintaining a footprint suitable for modern compact PCB designs. This makes it particularly popular in industrial control systems, power distribution modules, telecommunications equipment, and automotive electronics where both performance and miniaturization are important considerations. Ceramic capacitors in the 1808 package typically offer good high-frequency performance and stable behavior across moderate temperature ranges, making them suitable for general-purpose industrial applications. They are often selected for bypass and decoupling functions near integrated circuits, where their low equivalent series resistance (ESR) and inductance (ESL) help suppress voltage transients and reduce electromagnetic interference. When selecting a specific MLCC part number, engineers consider the required capacitance value, voltage rating, dielectric material type, and temperature stability characteristics. The 1808HC series from AVX is recognized for consistent quality and reliable performance in demanding industrial environments. This particular part number would be specified when the exact combination of package size, capacitance value, voltage rating, and temperature characteristics matches the design requirements of a given application. The compact 1808 package also simplifies assembly processes and reduces overall component cost compared to larger alternatives, without sacrificing the electrical performance needed for many industrial circuits. This combination of practical benefits explains why 1808-size MLCCs remain widely used across diverse engineering applications despite the availability of larger and smaller options.
