08055A4R7JAT4A

The AVX 08055A4R7JAT4A is a thin-film chip capacitor designed for high-reliability applications in industrial and commercial electronics. This component belongs to AVX's established line of precision capacitors, engineered to meet demanding requirements across telecommunications, aerospace, medical devices, and military equipment where stable performance and long-term reliability are critical. The "08055" designation indicates this capacitor uses a 0805 metric package (2.0mm × 1.25mm), a widely standardized surface-mount form factor that balances compact size with practical handling and assembly characteristics. This size makes it suitable for space-constrained circuit designs while remaining large enough to deliver meaningful capacitance values without excessive cost. The thin-film construction technology provides superior performance compared to standard ceramic capacitors in several key areas, including lower distortion, excellent frequency stability, and minimal capacitance drift over time and temperature cycling. AVX thin-film capacitors in this series are typically specified where circuit designers need predictable, stable capacitance across operational temperature ranges and frequency bands. They exhibit lower equivalent series resistance (ESR) and lower equivalent series inductance (ESL) compared to alternatives, making them particularly valuable in high-frequency signal conditioning, precision analog circuits, and filtering applications. The thin-film dielectric material also generally demonstrates reduced aging effects and better performance under AC signal conditions than conventional dielectrics. Engineers commonly select AVX thin-film chip capacitors for coupling and decoupling applications, precision measurement circuits, audio equipment, and RF/microwave signal processing where capacitance accuracy and stability directly impact system performance. The 0805 package size is especially popular in mixed-signal designs where multiple small-value capacitors must be deployed densely across a PCB for effective noise management and signal integrity. The "4R7" portion of the part number typically indicates the capacitance value, following standard electronic component marking conventions. The suffix codes reference specific performance grades, voltage ratings, and manufacturing specifications within AVX's product matrix, ensuring that this particular part number represents a specific combination of electrical characteristics and reliability certifications. For applications requiring capacitors with tighter tolerances, superior frequency response, minimal temperature coefficient variations, or compliance with aerospace and military standards, the AVX thin-film approach offers measurable advantages over commodity alternatives. This makes the 08055A4R7JAT4A a preferred choice for design engineers who prioritize long-term performance stability and regulatory compliance over lowest unit cost.
