08055A470GAT4A

The AVX 08055A470GAT4A is a thin-film chip capacitor designed for high-reliability applications in industrial, military, and aerospace electronics. This component represents a precision capacitive solution from AVX's established line of 0805 surface-mount capacitors, a package size widely recognized for balancing compact footprint with practical handling and assembly characteristics. Thin-film capacitors are manufactured using vacuum deposition techniques that create extremely uniform dielectric layers, resulting in exceptional consistency and stability compared to conventional ceramic or film technologies. This manufacturing approach makes them particularly valuable in applications where capacitance tolerance, temperature stability, and long-term reliability are critical performance factors. The 0805 package dimensions make this component suitable for modern PCB designs where space constraints are significant but not extreme, offering a practical middle ground in the surface-mount landscape. The "470" designation indicates a 47nF capacitance value, a commonly used value in filtering, coupling, and bypass applications across analog and mixed-signal circuits. Engineers frequently specify capacitors in this range for power supply filtering, RF circuits, signal conditioning, and timing applications. The thin-film construction ensures predictable behavior across temperature variations and operating conditions, making it particularly suitable for environments where performance drift could impact system reliability. AVX thin-film chip capacitors in the 0805 format are commonly found in defense electronics, medical instrumentation, precision measurement equipment, and telecommunications infrastructure where stringent reliability requirements and environmental specifications demand superior performance. The precision tolerance and stability characteristics make this component appropriate for applications requiring close capacitance control rather than general-purpose use cases. Engineers might specify this exact part rather than alternatives when designs require the combination of small form factor with the enhanced stability and consistency that thin-film technology provides. While ceramic chip capacitors offer lower cost and smaller packages, they exhibit greater temperature coefficient effects and capacitance variation under bias voltage. Larger film capacitors provide excellent performance but consume more board space. The AVX 08055A470GAT4A occupies a specific performance-to-size niche that appeals to designers prioritizing reliability and precision in space-constrained applications. The component is designed for lead-free solder assembly and is compatible with standard reflow processes used in modern electronics manufacturing. Its qualification in military and aerospace applications suggests it meets rigorous quality and reliability standards that extend beyond typical commercial-grade components, making it a dependable choice for demanding industrial environments where component failure carries significant consequences.
