18251A362JAT2A

The AVX 18251A362JAT2A is a tantalum capacitor designed for demanding industrial and electronic applications requiring high reliability and stable performance. Tantalum capacitors from AVX are widely recognized for their combination of high volumetric efficiency, low leakage current, and excellent frequency characteristics, making them suitable for precision circuitry where space constraints and performance consistency matter. This component belongs to AVX's established tantalum capacitor portfolio, which serves applications spanning military, aerospace, medical devices, telecommunications infrastructure, and industrial control systems. The specific part number designation indicates a surface-mount configuration typical of modern electronics manufacturing, allowing for compact board layouts and automated assembly processes. Tantalum capacitors in this family are valued in filtering, decoupling, and energy storage roles where miniaturization without sacrificing performance is essential. Tantalum capacitors operate by using tantalum pentoxide as the dielectric material, which provides superior dielectric strength compared to conventional ceramic or aluminum electrolytic alternatives. This characteristic enables engineers to achieve higher capacitance values in smaller packages, a critical advantage in space-constrained applications like portable instrumentation, avionics, medical implants, and compact industrial electronics. The technology also delivers predictable behavior across temperature ranges and frequency spectra, supporting stable circuit operation in challenging environments. Engineers typically specify AVX tantalum capacitors when applications demand proven reliability with established long-term performance history. This is particularly relevant in military, medical, and safety-critical systems where component failure carries significant consequences. The extended temperature operating range and low equivalent series resistance (ESR) of quality tantalum capacitors make them preferable to alternatives in power supply filtering, signal conditioning, and timing circuits where performance degradation cannot be tolerated. The 18251A362JAT2A designation follows AVX's established naming conventions, which encode package geometry, voltage rating, capacitance value, and tolerance information. This standardized approach allows design engineers familiar with AVX's product ecosystem to quickly identify suitable alternatives and understand performance parameters within the series. Tantalum capacitors do require proper circuit design consideration, particularly regarding voltage derating and reverse-voltage protection, as the technology is sensitive to voltage stress beyond rated limits. However, when properly applied within specifications, they deliver excellent long-term stability and predictable behavior, which is why they remain the preferred choice for high-reliability applications despite the availability of newer competing technologies.
