1825SA470JAT1A

The 1825SA470JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This component represents the type of capacitor commonly found in industrial electronics, telecommunications equipment, power management circuits, and consumer electronics applications where reliable energy storage and signal filtering are required. Multilayer ceramic capacitors like this model are constructed from alternating layers of ceramic dielectric material and metallic electrodes, stacked and sintered to create a compact package with significant capacitance in a small footprint. The "1825" designation refers to the package size—specifically a surface-mount format measuring approximately 18mm by 25mm—making it suitable for automated assembly on printed circuit boards where space efficiency matters but miniaturization to ultra-small packages is not the primary constraint. The part number suffix "SA" typically indicates the voltage class and dielectric type used in this particular capacitor series. AVX's capacitors in this family are engineered for general-purpose industrial and commercial applications, offering a balance between performance, reliability, and cost-effectiveness. These components are designed to withstand standard temperature operating ranges appropriate for most indoor electronic equipment environments. Engineers select this specific part number when they need a capacitor with particular capacitance value, voltage rating, and package size that fits their circuit design requirements. The surface-mount package format allows for efficient production throughput in modern manufacturing environments, reducing assembly labor and improving overall system reliability compared to through-hole alternatives. The use of ceramic dielectric material provides stable capacitance across moderate temperature variations and delivers low equivalent series resistance, which is beneficial in filtering, coupling, and decoupling applications. This component would typically be specified in power supply circuits, audio equipment, industrial control systems, and various consumer electronics where intermediate-value capacitors are needed for energy buffering or AC signal filtering. The larger package size compared to smaller MLCCs allows for higher voltage ratings or capacitance values without requiring specialized handling, making it a practical choice for cost-conscious designs that don't require the smallest possible components. When evaluating alternatives, engineers would consider other AVX capacitors in similar package sizes and voltage classes, as well as competing manufacturers' offerings, based on the exact electrical requirements of their specific circuit application, thermal environment, and production volume requirements.
