1812AA561KAT1A

# 1812AA561KAT1A - AVX Thin Film Chip Capacitor The 1812AA561KAT1A is a thin film chip capacitor manufactured by AVX, a recognized producer of passive electronic components. This part belongs to the 1812 chip package family, which designates a surface-mount form factor measuring 1.8mm by 1.2mm. Thin film capacitors in this size class are engineered for high-frequency applications and precision filtering where stable performance over temperature and frequency ranges is essential. Thin film technology provides superior characteristics compared to standard ceramic capacitors for certain demanding applications. These capacitors are manufactured using thin film deposition techniques that enable tighter tolerance control, lower equivalent series resistance (ESR), and more stable capacitance values across operating conditions. The "AA" designation in AVX's naming convention typically indicates the voltage class and materials used in the device's construction. The "561" portion of the part number encodes the capacitance value and multiplier according to standard electronics industry conventions, representing a specific capacitance within AVX's product family. Engineers specify the 1812AA561KAT1A in applications requiring precision analog filtering, signal conditioning, power supply decoupling in high-speed digital circuits, and RF/microwave filtering stages. The compact 1812 package allows integration into space-constrained designs while maintaining electrical performance. These capacitors are particularly valued in telecommunications equipment, test and measurement instruments, medical devices, and aerospace/defense systems where reliability and performance consistency matter significantly. The chip capacitor construction method and AVX's manufacturing quality make this part suitable for harsh industrial environments and applications requiring extended operational life. The surface-mount package facilitates automated assembly processes, reducing manufacturing complexity compared to through-hole alternatives while enabling higher circuit density. When selecting the 1812AA561KAT1A over alternatives, engineers typically prioritize the combination of package efficiency, thin film performance advantages, and AVX's reputation for consistent production quality. This part competes favorably against standard multilayer ceramic capacitors when tighter tolerance specifications, lower losses, or superior frequency stability are required. Its form factor also provides advantages over larger discrete packages when board real estate is constrained. For applications involving high-frequency signal paths, precision reference circuits, or systems where capacitor performance drift could compromise overall accuracy, the thin film construction and proven AVX manufacturing process make this component a reliable choice backed by established component history in professional electronics markets.
