1825SC472KAT1A

The 1825SC472KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive components for industrial and commercial electronics. This component belongs to the 1825 case size family, which corresponds to metric dimensions of 4.5mm × 3.2mm, a widely used standard in compact electronic assemblies where space efficiency is important but component accessibility remains practical. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions in power distribution, signal coupling, filtering, and noise suppression across countless applications. The "SC" designation in this part number indicates this capacitor is designed with specific electrical characteristics suited to standard commercial applications. These capacitors are constructed from multiple layers of ceramic dielectric material with interleaved metal electrodes, allowing manufacturers to achieve relatively high capacitance values in small physical packages. The 1825 package size strikes an important balance in industrial design. It is substantially smaller than older through-hole or larger surface-mount alternatives, enabling dense circuit layouts essential in modern control systems, power electronics, and instrumentation. Yet it remains large enough to handle meaningful current and voltage levels without the extreme miniaturization challenges of 0402 or 0201 packages, making it a practical choice for manufacturing and field repair scenarios. AVX's ceramic capacitor offerings in this family are commonly specified in industrial power supplies, motor drives, LED lighting controllers, telecommunications equipment, and automation control boards. Engineers typically select this specific part number and package size when they need reliable filtering or coupling capacitance in space-constrained designs where the 1825 form factor optimizes the circuit board layout without requiring surface-mount soldering equipment designed for ultra-miniature components. The MLCC technology offers several advantages that make it preferable to alternative capacitor types in many applications. Ceramic capacitors provide stable performance across wide temperature ranges, exhibit low equivalent series resistance (ESR), and deliver excellent high-frequency characteristics. They are also highly cost-effective for volume production, which makes them standard in industrial equipment manufactured at scale. For engineers evaluating alternatives, the 1825 case size represents a practical middle ground compared to larger packages or multilayer ceramic alternatives with different dimensional profiles. The AVX brand carries strong reliability credentials and is widely recognized by procurement and engineering teams in industrial sectors, making this part a straightforward specification choice for designs requiring proven performance and supply chain confidence.
