12065A621FAT2A

The AVX 12065A621FAT2A is a multilayer ceramic capacitor (MLCC) designed for high-reliability applications in industrial and consumer electronics. This component belongs to AVX's established MLCC product family, representing a common form factor used extensively in modern circuit design where compact size and stable performance are essential requirements. Multilayer ceramic capacitors like this unit are fundamental passive components found in virtually every category of electronic equipment. They serve critical functions including energy storage, signal filtering, noise suppression, and decoupling in power supply circuits. The 12065 designation refers to the physical package dimensions, indicating a surface-mount component with a footprint suitable for automated assembly on standard PCBs. This size category represents a practical balance between capacitance density and ease of handling in production environments. Engineers typically specify AVX capacitors in this family for applications demanding consistent performance across temperature and frequency ranges, along with long-term reliability. These components are particularly common in industrial control systems, telecommunications infrastructure, automotive electronics, power management circuits, and precision instrumentation. The ceramic dielectric technology provides stable capacitance characteristics and low equivalent series resistance (ESR), making them suitable for both filtering and decoupling roles in signal integrity-critical designs. The "FAT" designation within the part number indicates specific dielectric material properties and performance characteristics within AVX's product range. This specification typically reflects a particular formulation optimized for specific voltage and temperature operating windows. Engineers selecting this exact part number are usually working within established design specifications where the particular combination of voltage rating, capacitance value, and temperature stability characteristics align with their circuit requirements. Compared to alternative capacitor technologies, ceramic MLCCs offer significant advantages in terms of compact size, cost-effectiveness at volume, and the ability to achieve high capacitance values in small footprints. The surface-mount design enables automated placement and reflow soldering, reducing assembly costs and improving manufacturing consistency. However, the specific selection of this part number suggests the design requires the particular electrical characteristics—such as voltage class, capacitance tolerance, or dielectric stability—that distinguish this variant from other options in the broader MLCC market. For engineers evaluating component options, the critical consideration is matching the part's rated specifications against circuit requirements for voltage, temperature operating range, and frequency response. This AVX component represents a well-established solution in industrial and commercial electronics design, offering proven reliability and consistent supply chain availability through established distribution channels.
