08055C391KAJ2A

The AVX 08055C391KAJ2A is a thin-film capacitor designed for precision applications requiring stable, reliable performance in compact form factors. This component belongs to the 0805 package family, which is a standard surface-mount size widely used across industrial electronics, telecommunications equipment, and precision instrumentation. Thin-film capacitors from AVX are engineered for applications where consistent capacitance stability, low dissipation factor, and predictable temperature behavior are critical. The 0805 package provides an excellent balance between small footprint and handling ease, making it suitable for high-density printed circuit board layouts common in modern industrial control systems, measurement devices, and signal conditioning circuits. This particular part number indicates a capacitor optimized for general-purpose applications across industrial and commercial temperature ranges. Engineers typically specify thin-film capacitors in this package when they need better tolerance control, lower parasitic effects, and more stable performance compared to standard ceramic capacitors. The technology offers reduced capacitance drift over temperature and time, making it valuable in precision analog circuits, filtering applications, and timing-critical designs where component consistency matters. Common application areas include industrial power supplies, precision data acquisition systems, audio signal processing, sensor interfaces, and control electronics. The compact 0805 size is particularly advantageous in space-constrained designs where board real estate is at a premium, yet performance requirements remain demanding. Manufacturers and system integrators choose AVX thin-film capacitors like the 08055C391KAJ2A when specifications call for repeatable electrical behavior and reduced component-to-component variation. This is especially important in medical devices, aerospace applications, and test equipment where reliability and measurement accuracy cannot be compromised. The thin-film construction provides superior performance compared to electrolytic or basic ceramic alternatives in applications sensitive to capacitance stability, ESR characteristics, or frequency response. The 0805 package format ensures compatibility with standard automated assembly processes, reducing manufacturing complexity and cost while maintaining the performance advantages of thin-film technology. This part represents a practical engineering choice for designers balancing performance requirements with practical manufacturing and cost considerations in demanding industrial applications. For exact electrical specifications, operating temperature range, and detailed performance characteristics of this specific part number, reference materials and technical documentation from AVX should be consulted during the design phase.
