1808AC472KAT1A

The 1808AC472KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established names in passive component design. This component belongs to the 1808 package family, which refers to the physical dimensions in metric notation (approximately 4.5mm x 2.0mm), making it a compact surface-mount device suitable for modern PCB layouts where space efficiency is important. Multilayer ceramic capacitors like this one are fundamental building blocks in electronic circuits, serving critical functions including energy storage, signal filtering, decoupling, and voltage stabilization. The "AC" designation within the part number typically indicates the dielectric material and general performance category, suggesting this capacitor is designed for general-purpose applications where stable performance across moderate temperature ranges is required. The 1808 package size represents a common mid-range footprint in capacitor selection. Engineers choose this size when they need a balance between space constraints and practical soldering and handling requirements. It's larger than 0603 or 0805 packages but smaller than 1812 or 1825 packages, making it ideal for applications where board density is significant but not extreme. This AVX component is typically specified in industrial control systems, consumer electronics, automotive modules, telecommunications equipment, and computer peripherals. Common circuit applications include power supply filtering on DC rails, noise suppression near integrated circuits, signal coupling and decoupling networks, and bypass filtering in mixed-signal designs. Engineers frequently encounter these capacitors in power management circuits, where they help reduce voltage ripple and transient noise. Ceramic capacitors in general are preferred for many applications because they offer excellent frequency response, compact form factors, cost-effectiveness at volume, and good reliability when properly applied. The 1808 package strikes a practical balance for many design teams working within standard manufacturing constraints. When selecting the 1808AC472KAT1A specifically, engineers would consider it for designs requiring the AVX manufacturing quality standard, the particular electrical characteristics of the AC dielectric series, and the proven compatibility with standard PCB assembly processes. AVX's manufacturing consistency makes this part suitable for applications where long-term reliability and repeatability across production batches are important factors. For exact electrical specifications including capacitance value, voltage rating, tolerance, temperature coefficient, and ESR characteristics, reference the manufacturer's technical documentation, as these details are critical to proper circuit design and should be confirmed against your specific application requirements.
