1825HC472KAT3A

The 1825HC472KAT3A is a multilayer ceramic capacitor manufactured by AVX, representing a versatile passive component widely used in industrial electronics, telecommunications equipment, and consumer applications. This component belongs to the high-capacitance ceramic capacitor family, designed to provide stable energy storage and filtering capabilities in compact form factors. Multilayer ceramic capacitors (MLCCs) like this part function as energy storage and filtering elements in electronic circuits. They are essential for smoothing voltage ripple, decoupling power supply noise, blocking DC signals while passing AC, and stabilizing circuit operation across various frequency ranges. The 1825 designation refers to the package size, indicating physical dimensions that balance performance requirements with space constraints in modern circuit board designs. The "HC" designation in this part number typically indicates this capacitor is formulated for high-capacitance applications, meaning it delivers substantial capacitance value relative to its physical size. This makes it particularly valuable in applications where board real estate is limited but significant capacitive performance is required. Such capacitors are commonly found in power management circuits, analog signal conditioning, RF/microwave equipment, industrial control systems, and audio frequency applications. AVX's ceramic capacitors in this series are engineered for reliability in demanding industrial environments. These components can withstand mechanical stress from thermal cycling, vibration, and shock that frequently occur in factory automation, test equipment, and harsh-environment applications. The multilayer construction provides improved performance characteristics compared to single-layer alternatives, including better frequency response and more stable behavior across operating conditions. Engineers typically specify this exact part when design requirements call for a specific combination of capacitance value, package size, and voltage rating that this component provides. The 1825 case size offers a middle ground between smaller 1206 or 1210 packages and larger alternatives, making it suitable for applications requiring good capacitance density without excessive board footprint. Compared to electrolytic capacitors, MLCCs like this offer superior high-frequency performance, longer operational life, and greater reliability in critical applications. The choice of this particular part number often reflects consideration of factors such as the required capacitance value (as encoded in the "472" portion of the designation), voltage rating compatibility, temperature coefficient characteristics, and proven performance history in similar applications. For engineers designing industrial control modules, switching power supplies, signal processing circuits, or communications equipment, this component provides a proven solution backed by AVX's manufacturing standards and quality assurance.
