18087A391JAT2A

The AVX 18087A391JAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, coupling, and decoupling applications in electronic circuits. This component belongs to AVX's established product family of surface-mount capacitors widely used across industrial, telecommunications, automotive, and consumer electronics applications. As a ceramic capacitor, this part functions to store and release electrical charge, making it essential for power supply filtering, high-frequency signal coupling, and noise suppression in electronic designs. MLLCs are preferred in modern electronics because they offer compact form factors, high volumetric efficiency, and reliable performance across a broad range of operating conditions. The part number designation indicates this capacitor features AVX's standard construction methods and packaging. Like other components in its family, it is designed for automated assembly processes, with a surface-mount configuration that allows for efficient placement on printed circuit boards using standard manufacturing equipment. The ceramic dielectric composition provides stable performance over typical industrial operating temperature ranges, making it suitable for applications where temperature fluctuations are a concern. Engineers typically specify this exact part when they need a cost-effective, proven capacitor solution with reliable electrical characteristics and consistent availability. AVX's reputation for quality manufacturing and adherence to industry standards makes their MLCC products a trusted choice in applications where component failure could impact system reliability. The specific part number allows procurement teams to ensure exact replacement compatibility across production batches and to maintain consistency across multiple product revisions. Multilayer ceramic capacitors like this are fundamental building blocks in modern power distribution networks. They work alongside larger bulk capacitance elements to handle high-frequency transient currents on supply rails, protecting sensitive integrated circuits from voltage spikes and noise. In telecommunications equipment, automotive electronics, and industrial control systems, multiple MLLCs are typically deployed throughout the circuit to achieve comprehensive filtering across different frequency ranges. The 18087A391JAT2A would be considered in designs where component size constraints and board real estate are important factors. Rather than using single larger capacitors, designers often implement multiple smaller MLLCs to achieve both the required total capacitance and improved high-frequency performance through their lower equivalent series resistance and inductance characteristics. For engineers evaluating capacitor options, this AVX part represents a standard industrial-grade solution offering proven performance, established supply chains, and compatibility with conventional manufacturing processes. Its selection would typically reflect design requirements for filtering or energy storage rather than specialized high-performance applications.
