08055A121JAT2A

The 08055A121JAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components for industrial and commercial applications. This component is housed in a 0805 surface-mount package, making it suitable for modern printed circuit board assembly where space efficiency and automated manufacturing are priorities. Multilayer ceramic capacitors like this unit are among the most widely used capacitive components in electronics manufacturing. They function by storing electrical charge between multiple ceramic layers separated by metallic electrodes, enabling compact energy storage and signal conditioning across a broad range of electronic circuits. The 0805 form factor represents a standard footprint that balances component density with practical handling and soldering characteristics, widely adopted across consumer electronics, telecommunications, industrial control systems, and automotive applications. The part number designation indicates this capacitor belongs to AVX's established MLCC family, which serves general-purpose capacitance needs in applications requiring stable performance across standard operating conditions. Engineers typically specify components from this series for decoupling, filtering, bypass, and coupling functions within power supplies, audio circuits, RF applications, and digital logic systems. The multilayer construction provides reliable performance in environments where consistent capacitance and low equivalent series resistance are important. Designers often choose AVX MLCCs in the 0805 package when they need a balance between miniaturization and thermal performance. The compact size allows for high-density circuit layouts while maintaining adequate surface area for thermal dissipation during manufacturing and operation. This package size is particularly common in applications ranging from portable battery-powered devices to stationary industrial equipment where space on the PCB is limited but reliability cannot be compromised. The specific part number 08055A121JAT2A encodes information about the capacitor's electrical characteristics and construction, with the designation allowing for precise specification and traceability in production environments. Engineers working with legacy designs, medical devices, industrial controllers, or systems requiring component consistency and long-term availability often specify exact part numbers rather than generic equivalents, ensuring manufacturing repeatability and reducing qualification risks. For applications requiring a compact, proven ceramic capacitor solution with the reliability and consistency associated with AVX manufacturing, this component represents a standard industrial-grade option suitable for incorporation into a wide variety of electronic assemblies.
