08055A200J4T2A

The AVX 08055A200J4T2A is a thin-film capacitor designed for precision applications requiring stable performance across demanding operating conditions. This component belongs to the 0805 package family, a standard surface-mount form factor widely adopted in modern electronics manufacturing for its balance of compact size and ease of handling in automated assembly processes. Thin-film capacitors represent a specialized category within the broader capacitor market, distinguished by their construction method and resulting performance characteristics. These components are manufactured using vacuum deposition techniques that create extremely thin dielectric layers, yielding capacitors with superior stability, low distortion, and predictable behavior over time. The 0805 package designation indicates a rectangular surface-mount footprint measuring 2.0mm by 1.25mm, making it suitable for dense PCB layouts where space efficiency is critical. The "200J" marking in the part number indicates the capacitance value and tolerance class of this component. Capacitors with J-tolerance ratings are specified for applications where moderate precision is adequate but consistency and reliability remain important. This makes them suitable for filtering, coupling, and bypassing applications across industrial and commercial electronics, rather than precision instrumentation where tighter tolerances would be necessary. Engineers typically specify thin-film capacitors like this model in audio frequency applications, precision measurement systems, analog signal conditioning circuits, and filtering stages where dielectric absorption and distortion must be minimized. The construction method of thin-film capacitors results in significantly lower equivalent series resistance (ESR) and equivalent series inductance (ESL) compared to conventional ceramic alternatives, making them valuable in high-frequency coupling and decoupling applications. The 0805 package size makes this component practical for modern consumer and industrial electronics that require miniaturization without sacrificing performance. Designers choose this specific part when they need the stability advantages of thin-film construction in a universally compatible package size that integrates seamlessly with standard manufacturing equipment and assembly processes. This component would be specified over alternatives in applications where the superior frequency response and minimal distortion characteristics of thin-film technology justify the typically higher cost compared to conventional ceramic or electrolytic capacitors. Its reliability and predictable aging characteristics make it particularly valuable in professional audio equipment, precision measurement instrumentation, and long-lifecycle industrial control systems where component replacement is difficult or costly.
