2225AC821KAT1A

The 2225AC821KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose and industrial electronic applications. This component belongs to the 2225 case size family, which represents a larger surface-mount format that offers higher capacitance density and robust mechanical construction compared to smaller chip capacitor packages. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic circuit. They function to store electrical energy, filter noise, couple or decouple signals, and stabilize voltage supplies. The MLCC technology offers reliable performance across a wide temperature range and maintains stable capacitance characteristics under varying electrical stress, making these capacitors suitable for demanding industrial environments. The 2225 package format is particularly valued in applications where moderate to higher capacitance values are required within reasonable physical space constraints. This size strikes a practical balance between component density and handling convenience during manufacturing, making it common in power supply circuits, signal conditioning, and general decoupling applications throughout industrial control systems, telecommunications equipment, and automotive electronics. AVX is a well-established manufacturer known for producing high-reliability ceramic capacitors used in aerospace, defense, and industrial sectors. Components from this manufacturer are typically specified where long-term stability, consistent performance, and resistance to environmental stresses are critical factors. AVX capacitors undergo rigorous quality control and are often selected for applications requiring documented traceability and consistent batch-to-batch performance. Engineers typically specify the 2225AC821KAT1A when they need a specific capacitance value in the ceramic chip format with AVX's quality assurance standards. The exact capacitance designation embedded in the part number indicates a particular value selection within AVX's standard series. This part would be chosen over alternatives based on several factors: the required capacitance value itself, the need for AVX's specific manufacturing quality or certification level, voltage rating requirements for the application, and compatibility with existing procurement and supply chain standards. The surface-mount configuration allows for automated assembly using standard pick-and-place equipment, reducing manufacturing costs and improving production throughput in high-volume applications. The larger 2225 footprint also provides better mechanical stability and lower susceptibility to handling damage compared to smaller packages, which is particularly advantageous in ruggedized or harsh industrial environments. This capacitor would be specified in power distribution networks, filtering stages, coupling circuits, and anywhere stable, reliable capacitive behavior is needed without requiring specialized high-frequency or high-temperature characteristics beyond the ceramic dielectric's normal operating range.
