08055A120KAT2A

The 08055A120KAT2A is a surface-mount multilayer ceramic capacitor manufactured by AVX, a recognized producer of passive electronic components. This part belongs to the 0805 package family, one of the most widely used standard sizes in modern electronics manufacturing. The component is designed for general-purpose energy storage, filtering, and signal coupling applications across consumer, industrial, and automotive electronics. Multilayer ceramic capacitors (MLCCs) like this model function by storing electrical charge across multiple thin ceramic dielectric layers. The 0805 package format—representing 0.080 inches by 0.050 inches—offers a practical balance between compact size and handling ease in both manual assembly and high-speed automated production environments. This standardized footprint makes the part compatible with virtually all modern PCB assembly equipment, reducing manufacturing complexity and cost. The AVX construction quality in this capacitor makes it suitable for applications demanding reliability in demanding environments. Engineers commonly specify MLCCs in this size range for decoupling and bypass filtering near integrated circuits, where they suppress high-frequency noise and stabilize power supply voltages. They are also used in signal path applications including coupling, blocking, and tuning circuits. The ceramic dielectric composition provides stable performance across typical industrial operating temperature ranges, making these capacitors reliable for both commercial and extended-temperature applications. The 0805 package size represents an optimal choice for space-constrained designs where smaller 0603 or 0402 packages might offer insufficient capacitance values, while larger packages would consume unnecessary board area. This middle-ground positioning explains why 0805 MLCCs remain industry standards in everything from consumer portable electronics to industrial control systems and telecommunications equipment. When selecting this specific part number, engineers typically prioritize the combination of proven AVX reliability, standardized package compatibility, and the likelihood of long-term availability. The 0805 format also offers superior mechanical robustness compared to smaller alternatives, particularly in applications subject to thermal cycling or vibration. For designers building in-house assembly capabilities or working with contract manufacturers, specifying established standard parts like the 08055A120KAT2A streamlines procurement, reduces design risk, and simplifies inventory management. This component represents the kind of foundational passive device that appears in virtually every modern electronic system, from industrial equipment and power supplies to consumer devices and embedded systems.
