12065A102KAT2A

# AVX 12065A102KAT2A Product Description The AVX 12065A102KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose and industrial applications requiring reliable energy storage and filtering across a broad range of operating conditions. As a component in AVX's established capacitor lineup, this part serves as a building block in power supplies, signal conditioning circuits, and embedded systems where compact form factors and cost-effective performance are required. Multilayer ceramic capacitors function by storing electrical charge across multiple alternating layers of ceramic dielectric material and metallic electrodes. They provide rapid charge and discharge characteristics, making them ideal for decoupling, bypass filtering, and energy smoothing applications. The 12065 designation refers to the package size—a surface-mount form factor that balances board real estate efficiency with handling and assembly considerations in automated manufacturing environments. Engineers commonly specify ceramic capacitors like this one in power distribution networks to suppress voltage transients and maintain stable supply rails for digital and analog integrated circuits. They are equally prevalent in RF circuits, timing applications, and noise filtering stages where their low equivalent series resistance and inductance provide effective high-frequency performance. The multilayer construction enables significant capacitance density, allowing designers to meet capacitance requirements without excessive board space consumption. The "A" designation within AVX's part numbering scheme typically indicates a standard dielectric class suited for applications where capacitance stability across temperature and voltage ranges is important but not critical. This positioning makes such capacitors appropriate for mainstream industrial, telecommunications, and consumer electronics applications rather than demanding military or aerospace contexts. Reasons an engineer might select this specific part include AVX's well-established quality reputation, the balance of performance and cost in the standard capacitor class, compatibility with standard surface-mount assembly processes, and proven long-term availability. For designers working within established supply chains or migrating from previous AVX designs, part continuity and manufacturer support become additional specification drivers. The compact 12065 package integrates readily into dense circuit board layouts while maintaining sufficient lead spacing for automated pick-and-place equipment and solder reflow processes. Engineers working on space-constrained applications—such as portable instrumentation, control modules, or distributed sensor networks—often favor this form factor for its practical balance of density and manufacturability.
