1808GA101KAT1A

The AVX 1808GA101KAT1A is a thin-film chip capacitor designed for high-frequency and precision applications in industrial and professional electronic equipment. This component belongs to AVX's established line of surface-mount capacitors engineered to meet demanding performance requirements in filtering, coupling, and tuning circuits. The 1808 designation indicates this is an 0603 metric package size (approximately 1.6mm x 0.8mm), making it suitable for compact circuit board designs where space constraints are critical. The thin-film construction is characteristic of components specified for applications requiring superior frequency stability, low dielectric loss, and predictable performance across temperature ranges. This construction method differentiates it from standard ceramic capacitors, offering engineers more consistent electrical behavior, particularly valuable in RF circuits, instrumentation, and signal conditioning applications. The GA series identifier points to this part's role in precision applications where tolerance control and long-term stability are essential. Thin-film capacitors like this are commonly selected for phase-critical circuits, impedance matching networks, and filter designs where capacitance variation could compromise system performance. Industries ranging from telecommunications equipment to medical instrumentation to aerospace electronics regularly specify thin-film components to ensure circuit reliability and predictability. Typical application areas include high-frequency filtering in power supplies, coupling stages in RF amplifiers, timing networks in precision oscillators, and resonant circuits in sensor interfaces. The surface-mount package format allows for automated assembly processes, reducing manufacturing costs while maintaining quality in high-volume production environments. Engineers often choose this specific part over alternatives when designs demand the combination of small footprint with stable, repeatable electrical characteristics. Unlike standard multilayer ceramic capacitors, thin-film technology provides superior linearity and resistance to voltage coefficient effects, meaning the capacitance remains more stable under varying operating conditions. This makes the component particularly valuable in measurement and control systems where accuracy must be maintained over extended operational lifespans. The 1808GA101KAT1A represents a mature, well-established design from a manufacturer with deep expertise in capacitor technology. Specifying this exact part number ensures consistency in procurement and performance validation across production batches, which is important for original equipment manufacturers requiring traceable component genealogy and reliable supply chains. For engineers evaluating thin-film capacitors in this package class, this AVX component offers the combination of proven performance, established manufacturing processes, and availability through established distribution channels.
