08055A4R7BAT4A

The AVX 08055A4R7BAT4A is a thin-film chip capacitor designed for high-reliability applications requiring precision performance and compact board integration. This component represents AVX's commitment to delivering stable, dependable passive components for demanding industrial and commercial electronics. Thin-film capacitors like this model are constructed using advanced deposition techniques that create extremely thin dielectric layers between conductive plates. This construction method yields capacitors with exceptional stability, low parasitic inductance, and predictable behavior across temperature and frequency ranges. The 0805 package size (approximately 2.0mm × 1.25mm) makes this component ideal for space-constrained applications while maintaining sufficient lead size for reliable soldering on modern PCBs. The 4.7µF capacitance value positions this part in the mid-range for capacitance applications, making it suitable for buffering, coupling, and filtering functions across numerous circuit topologies. Engineers frequently specify thin-film capacitors in this value range for decoupling in analog signal paths, timing circuits, and precision measurement equipment where capacitance stability is critical. Typical applications include aerospace and defense electronics, medical instrumentation, high-precision industrial control systems, and telecommunications infrastructure. These environments demand components that maintain consistent electrical characteristics over extended operating lifespans despite exposure to temperature cycling, vibration, and electromagnetic interference. The thin-film construction provides superior performance compared to standard ceramic capacitors in these demanding scenarios, particularly when circuit performance depends on minimal capacitance drift and low dissipation factor. Engineers select AVX thin-film capacitors over alternatives when designs require lower ESR (equivalent series resistance), tighter capacitance tolerances, or superior frequency response characteristics. The 4.7µF value in 0805 packaging offers a practical balance between component size and performance, eliminating the need for larger packages while avoiding the cost and board space implications of using multiple smaller capacitors in parallel. The AVX brand carries significant weight in critical applications, as the manufacturer's quality control and reliability reputation make these components preferred choices for original equipment manufacturers in aerospace, defense, and medical sectors where component failure carries unacceptable consequences. Specifying established, thoroughly documented components from reputable manufacturers reduces design risk and streamlines qualification processes for regulated industries. This capacitor integrates seamlessly into automated assembly processes, supporting modern manufacturing efficiency while delivering the electrical performance characteristics that complex analog and mixed-signal designs require for optimal operation.
