08055A430FAT2A

The AVX 08055A430FAT2A is a thin-film chip capacitor designed for precision applications requiring stable capacitance performance across temperature and frequency ranges. This component belongs to AVX's established family of 0805 surface-mount capacitors, a standard package size widely used in modern electronic assembly processes. Thin-film capacitors are manufactured using vacuum deposition techniques to create highly uniform dielectric layers, resulting in superior performance compared to conventional ceramic or film technologies in demanding applications. The 0805 package format (measuring approximately 2.0mm x 1.25mm) makes this component compatible with standard pick-and-place equipment and industry-standard PCB layouts, reducing design and manufacturing complexity. This capacitor is particularly valued in applications where capacitance stability, low distortion, and predictable performance under varying operating conditions are critical requirements. Common uses include precision analog signal conditioning, high-frequency filtering, coupling and decoupling circuits in instrumentation, medical device electronics, aerospace and defense systems, and audio-grade filtering applications where component quality directly impacts system performance. The thin-film construction provides several inherent advantages over ceramic alternatives. These capacitors typically exhibit lower equivalent series resistance (ESR), reduced voltage coefficient effects, and minimal microphonic behavior—making them ideal for low-noise audio circuits and sensitive measurement equipment. The technology also provides excellent frequency response characteristics and stable performance across a broad temperature range without the reliability concerns sometimes associated with ferroelectric ceramic materials. Engineers specify thin-film capacitors like the 08055A430FAT2A when design requirements demand precise, predictable capacitance values that remain stable throughout the product's operational life. This is particularly important in legacy circuit designs where component matching and performance consistency affect overall system calibration, or in new designs where tight tolerances are necessary to meet performance specifications without requiring active component tuning. The 0805 package size positions this component as a practical choice for space-constrained designs that still require the performance benefits of thin-film technology. It offers a balance between the smaller 0603 package (which may limit capacitor construction options) and larger packages that consume excess PCB real estate. For engineers evaluating capacitor options, the AVX 08055A430FAT2A represents a component selected when the application demands the reliability and performance characteristics of thin-film construction in a widely-supported surface-mount format. It serves applications ranging from consumer electronics requiring exceptional audio quality to industrial instrumentation and defense systems where long-term performance stability is non-negotiable.
