08055A391KAT4A

The AVX 08055A391KAT4A is a thin-film multilayer ceramic chip capacitor designed for general-purpose and timing circuit applications in industrial and consumer electronics. This component belongs to AVX's established line of surface-mount capacitors, featuring a compact 0805 package size that makes it suitable for modern PCB designs where space optimization is critical. Multilayer ceramic capacitors (MLCCs) like this model are fundamental building blocks in electronic circuits, serving functions including signal coupling, decoupling, filtering, and energy storage. The 0805 package format—measuring approximately 2.0 x 1.25 millimeters—represents a widely standardized size that balances component density with ease of assembly on automated pick-and-place equipment. This standardization makes the part compatible with most modern manufacturing processes and design tools. AVX's thin-film ceramic capacitor technology is recognized for stability and reliability across consumer, industrial, and automotive applications. Components in this family are commonly specified in applications requiring consistent performance over time, such as audio circuits, power supply filtering, RF coupling stages, and precision timing applications. The multilayer construction provides capacitance in a very small footprint, allowing designers to meet increasingly stringent size and weight requirements without sacrificing circuit performance. Engineers typically specify AVX ceramic capacitors when they require proven reliability, established supply chain availability, and predictable electrical behavior over a range of operating conditions. The 0805 package size in particular offers advantages for high-volume production runs, as the part is standard across multiple suppliers and manufacturing platforms. This reduces design risk and simplifies long-term component sourcing compared to more specialized package formats. The thin-film construction of AVX's multilayer ceramic capacitors generally provides lower equivalent series resistance (ESR) compared to some alternative technologies, which can be beneficial in switching power supplies and high-frequency applications. Additionally, the ceramic dielectric material used in these capacitors typically offers temperature stability suitable for industrial temperature ranges, making them appropriate for applications beyond consumer-grade consumer electronics. Common application areas include telecommunications equipment, industrial control systems, medical device electronics, computer motherboards and peripherals, and consumer appliances. The versatility of the 0805 form factor and the established performance characteristics of AVX's multilayer ceramic technology make this part a practical choice for design engineers seeking a reliable, readily available component for general-purpose capacitive functions in their circuits.
