12065C102K4T4A

The 12065C102K4T4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose applications across industrial and consumer electronics. This component belongs to the established family of surface-mount capacitors commonly used in power supply filtering, signal coupling, and noise suppression circuits. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic design. They function by storing electrical charge between multiple ceramic layers, each with metallic electrodes, allowing designers to achieve significant capacitance values in compact physical packages. The 1206 case size indicates a surface-mount device measuring approximately 3.2mm × 1.6mm, representing a standard industrial footprint that balances ease of assembly with sufficient board real estate for stable mounting and soldering. The "02K" designation within the part number references the component's dielectric material and voltage rating class, which typically positions this capacitor for mid-range voltage applications common in logic circuits, power management modules, and control electronics. AVX's ceramic capacitor lines are recognized for stable performance across temperature variations and reasonable cost efficiency, making them suitable for cost-conscious designs where performance margins exist. Engineers specify this exact part number when they require a proven, readily available component with established supply chains and consistent manufacturing standards. The AVX brand carries particular value in industrial settings where traceability and long-term availability support production continuity and field repairs. Designers also select specific part numbers like this when board space is constrained and the standard 1206 package offers the right balance of capacitance, voltage handling, and size without overspecifying higher-performance alternatives that would inflate bill-of-materials costs. Typical applications include decoupling and bypass filtering on microcontroller power pins, AC coupling in audio signal chains, snubbing networks for relay circuits, and general smoothing in power distribution systems. The component's reliability in these roles stems from decades of ceramic capacitor development and millions of production units operating successfully across automotive, industrial control, telecommunications, and consumer markets. Selection of this part reflects practical engineering judgment: it addresses common circuit needs without premium specifications or exotic materials, operates reliably across standard industrial temperature ranges, and maintains predictable electrical characteristics throughout its service life. For engineers designing robust systems requiring straightforward component sourcing and proven performance history, this AVX capacitor represents a dependable choice.
