08055A271J4T2A

The AVX 08055A271J4T2A is a surface-mount multilayer ceramic capacitor (MLCC) in the 0805 package size, commonly used across industrial electronics, telecommunications, automotive, and consumer applications. This component represents the standard workhorse of modern circuit design, offering reliable energy storage and signal filtering in compact form factor suitable for high-density PCB layouts. Multilayer ceramic capacitors like this part are fundamental passive components used for coupling, decoupling, filtering, and bypassing applications throughout electronic equipment. In power supply circuits, they stabilize voltage rails by absorbing transient current spikes and reducing noise. In signal processing circuits, they couple AC signals while blocking DC components or filter unwanted frequency content. The 0805 case size—measuring 2.0mm by 1.25mm—strikes an effective balance between compactness and ease of handling and soldering, making it economical for both manual prototype work and automated manufacturing. The "271J" designation in this part number encodes critical electrical characteristics. The J tolerance specification indicates the capacitance value has defined limits suitable for general-purpose filtering and coupling applications where precise values are less critical than reliability and consistency. This part belongs to AVX's established multilayer ceramic capacitor family, representing proven technology manufactured to established standards with consistent performance across temperature ranges typical for industrial and commercial-grade electronics. Engineers specify components like the 08055A271J4T2A when designing circuits requiring proven reliability, small footprint, and cost-effectiveness rather than specialized performance attributes. The 0805 package remains ubiquitous because it offers clear advantages: it's widely supported by PCB layout libraries and assembly equipment, second-sourcing options are available from multiple manufacturers, and procurement costs remain competitive. This standardization reduces design risk and manufacturing complexity compared to selecting rare or specialized alternatives. Applications commonly featuring this capacitor type include motherboards and computing equipment, industrial control systems, automotive electronics, power management modules, RF and analog signal conditioning circuits, and consumer appliances. The ceramic dielectric material provides stable performance across typical operating temperature ranges encountered in these markets. The surface-mount technology enables modern manufacturing methods including pick-and-place automation and reflow soldering. For designers choosing between available capacitor options, this part represents a practical specification where application requirements align with its capabilities: non-critical capacitance values, moderate voltage ratings, and standard operating conditions. Stocky availability of 0805 ceramic capacitors from established manufacturers like AVX makes this package size a default choice in commercial and industrial product design, balancing performance needs against practical constraints of cost, supply chain reliability, and manufacturing efficiency.
