2225HA471KAT1A

The 2225HA471KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established producers of passive components. This capacitor is housed in a 2225 case size, which represents a medium-format surface-mount package commonly used in electronics requiring a balance between board space efficiency and capacitance value. The alphanumeric designation within the part number indicates specific electrical and performance characteristics that define its role within a given circuit. Multilayer ceramic capacitors like this model serve as fundamental building blocks in modern electronic design. They function to store and release electrical energy, filter noise from power supplies, couple or decouple AC signals, and stabilize voltage rails across countless applications. The 2225 package size makes this part particularly suited to mid-range power applications where designers need reliable performance without consuming excessive PCB real estate. AVX's multilayer ceramic capacitors in this series are commonly specified in industrial control systems, telecommunications equipment, automotive electronics, and power management circuits. Engineers often encounter these capacitors in AC-DC power supplies, where they help manage transient voltage spikes and reduce electromagnetic interference. They also appear frequently in audio amplifiers, LED driver circuits, and precision instrumentation where signal conditioning is critical. The 2225 case format offers several advantages that influence design decisions. Compared to smaller 1206 or 1210 packages, the 2225 geometry allows for higher capacitance values or higher voltage ratings within the same dielectric material family. This makes it a practical choice when designers need specific electrical performance without resorting to larger packages or multiple components in parallel. The package also provides reasonable thermal characteristics for reflow soldering processes used in modern manufacturing. Engineers typically specify the 2225HA471KAT1A when their circuit requirements call for the exact electrical characteristics this part provides—whether related to its capacitance value, voltage rating, temperature stability class, or ESR (equivalent series resistance) profile. AVX's reputation for consistent quality and reliability across production batches makes this part attractive for applications requiring predictable performance over time and temperature cycling. This capacitor would typically be found in designs where component selection is driven by specific performance requirements rather than cost minimization alone. Its presence in a bill of materials usually indicates that the circuit designer has evaluated alternatives and determined this particular part's characteristics—its dielectric type, package size, and rated specifications—as optimal for the intended function.
