1825SC472KAT3A

The 1825SC472KAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized producer of passive electronic components. This component belongs to the 1825 case size family, which refers to the SMD (surface-mount device) package dimensions of 18mm × 25mm. MLCCs are among the most widely used capacitors in modern electronics due to their compact form factor, reliability, and cost-effectiveness. Multilayer ceramic capacitors function as energy storage and filtering elements in electronic circuits. They are constructed from alternating layers of ceramic dielectric material and metal electrodes, which are stacked and sintered together to create a compact package with significant capacitance in a small footprint. The "SC" designation in this part number typically indicates the series classification and dielectric material type used by AVX. The 1825 package size makes this capacitor suitable for applications requiring moderate to high capacitance values while maintaining reasonable board space efficiency. Engineers commonly specify capacitors in this size range for power supply filtering, signal coupling and decoupling, energy storage in switching power supplies, and noise suppression in industrial control systems, automotive electronics, and consumer electronics. Key reasons an engineer might select the 1825SC472KAT3A include its proven reliability in demanding environments, suitability for automated assembly processes, and AVX's reputation for consistent manufacturing quality. The larger case size compared to smaller 0805 or 1206 packages allows for higher voltage and capacitance ratings, making it appropriate when those performance levels are required without resorting to electrolytic capacitors or other bulkier alternatives. This component is typically used in applications operating at room to moderately elevated temperatures. The ceramic dielectric construction provides stable performance across temperature variations, though like all MLCCs, some capacitance variation with temperature should be expected and considered during circuit design. The 1825 form factor offers practical advantages for industrial applications where component reliability and accessibility are important. Compared to smaller SMD packages, it is easier to handle during repair and rework, and the larger size facilitates better thermal distribution in high-power applications. Engineers working with power distribution systems, industrial automation equipment, telecommunications infrastructure, and embedded systems frequently incorporate capacitors from the 1825 family as part of their filtering and energy management strategies. The combination of AVX manufacturing standards and the proven 1825 package specifications makes this component a dependable choice for applications where performance consistency is critical.
