1812SC682KAT1A

The AVX 1812SC682KAT1A is a multilayer ceramic capacitor (MLCC) in the 1812 surface-mount package size, a popular choice in electronics manufacturing for mid-range capacitance applications. This component belongs to AVX's established ceramic capacitor family, which has been widely adopted across industrial, consumer, and commercial electronics sectors for decades. The 1812 package designation refers to the physical dimensions of 18 mm by 12 mm, making it a moderately sized surface-mount component suitable for applications where board space is a consideration but component density is not at maximum. This package size strikes a practical balance, offering better capacitance-per-unit-area than smaller packages while remaining easy to handle and reflow on automated assembly lines. Ceramic capacitors in this series are used extensively in power supply filtering, signal coupling and decoupling, and voltage smoothing applications throughout industrial electronics. Engineers commonly specify them in circuits requiring stable capacitance across moderate temperature ranges, such as switching power supplies, amplifier circuits, audio equipment, and general-purpose DC filtering stages. The multilayer ceramic construction provides reliable performance in these roles while maintaining cost-effectiveness in production environments. The "SC" designation within this part number indicates this capacitor belongs to a specific performance class within AVX's portfolio, typically characterized by standard dielectric properties suitable for general-purpose industrial use rather than specialized high-frequency or high-voltage applications. This positioning makes it appropriate for the majority of standard power and signal conditioning tasks encountered in industrial equipment design. AVX's ceramic capacitor manufacturing process delivers consistent performance across temperature variations commonly encountered in industrial settings. These components integrate well with both legacy and modern circuit designs, making them a reliable specification for engineers maintaining existing product lines or developing new equipment that must interface with standard industry components. Engineers might select this exact part number when their circuit design calls for a specific capacitance value available in the 1812 package, and when they require a proven, readily-available component from an established manufacturer with established supply chains. The combination of the 1812 package size and AVX's manufacturing heritage makes this part suitable for applications where standardization and supply continuity are important considerations alongside electrical performance.
