08055A251KAT2A

The 08055A251KAT2A is a thin-film chip capacitor manufactured by AVX, designed for applications requiring stable, reliable capacitance in a compact surface-mount package. This component belongs to the 0805 family of capacitors, which are among the most widely used passive components in modern electronics due to their small footprint and versatility across voltage and capacitance ranges. Thin-film capacitors like this part are constructed using precision deposition techniques that create extremely uniform dielectric layers, resulting in excellent stability and low losses compared to many alternative capacitor technologies. This manufacturing approach makes them particularly suitable for applications where consistent performance over time and temperature is critical. The 0805 package size measures approximately 2.0mm by 1.25mm, making it ideal for high-density circuit board layouts common in industrial control systems, test equipment, automotive electronics, and telecommunications infrastructure. Engineers typically specify AVX thin-film chip capacitors when designing filtering, coupling, and decoupling circuits where predictable electrical performance is essential. These capacitors exhibit low equivalent series resistance (ESR) and stable capacitance characteristics across operating conditions, making them well-suited for RF applications, power supply circuits, and precision analog instrumentation. The compact 0805 footprint allows manufacturers to maintain smaller PCB sizes while maintaining performance requirements, which is particularly valuable in space-constrained applications. The "251K" designation in the part number indicates the capacitance value in picofarads using the standard three-digit code common to chip components. This specific value falls within a range frequently used in coupling and bypass applications throughout industrial electronics. AVX's manufacturing process ensures tight tolerances and consistent quality, which is why engineers in demanding applications—such as aerospace, medical device manufacturing, and mission-critical industrial control—often prefer this manufacturer's products. For engineers evaluating alternatives, AVX thin-film capacitors offer measurable advantages over standard dielectric variants in terms of temperature stability, frequency response, and long-term reliability. They are particularly valuable in applications where capacitor drift could impact system performance or where regulatory compliance demands documented component stability. The 0805 size remains a standard offering, ensuring continued availability and compatibility with existing design practices across the industry. This component is suitable for integration into new designs as well as repair and replacement of existing equipment, making it a practical choice for both OEM production and field maintenance applications.
