08055A751FAT2A

# 08055A751FAT2A Thin Film Capacitor The 08055A751FAT2A is a thin film capacitor manufactured by AVX, a recognized producer of high-reliability passive components. This part represents the 0805 surface-mount package class, making it suitable for modern PCB assembly processes where space efficiency and automated manufacturing are priorities. Thin film capacitors are constructed using a specialized dielectric material—typically polypropylene or polyester—deposited as an extremely thin layer between metal electrodes. This construction method enables several performance characteristics that distinguish thin film capacitors from ceramic alternatives. They generally offer superior frequency response, lower equivalent series resistance (ESR), and excellent stability across temperature ranges. These properties make them particularly valuable in applications where signal integrity and low distortion are critical requirements. The 0805 form factor places this capacitor in the small passive component category, with dimensions roughly 0.080 by 0.050 inches. Despite its compact footprint, capacitors in this package retain good current-carrying capability and thermal performance, making them popular in both consumer electronics and industrial equipment where board density is a consideration. Common applications for thin film capacitors of this type include power supply filtering, signal conditioning circuits, audio frequency coupling stages, and RF applications where phase stability matters. They are frequently found in medical devices, telecommunications equipment, industrial control systems, and precision instrumentation where reliability and predictable performance over time are non-negotiable. Their low ESR characteristics make them suitable for high-frequency switching power supplies and signal processing circuits requiring minimal insertion losses. Engineers typically specify thin film capacitors like the 08055A751FAT2A over ceramic alternatives when the application demands tighter tolerances, lower dissipation factor, or superior temperature coefficient stability. While ceramic capacitors have progressed significantly, thin film technology remains the preferred choice for audio circuits, precision analog applications, and situations where component aging or frequency-dependent behavior must be minimized. The AVX brand carries established reputation for manufacturing consistency and long-term availability, which influences specification decisions in aerospace, medical, and military-grade applications where component continuity throughout a product's lifecycle is essential. The thin film construction inherently provides self-healing properties under certain fault conditions, adding another layer of reliability for critical circuit positions. For engineers evaluating this part, consideration should be given to the application's frequency range, required ripple current handling, temperature operating environment, and long-term stability demands. The 0805 package's prevalence in modern manufacturing infrastructure also simplifies sourcing, assembly planning, and PCB design standardization.
