12105C682MAT2A

The 12105C682MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the established leaders in passive component design and production. This component belongs to the 1210 package family, which is a surface-mount device measuring 12.7mm by 10.2mm, making it suitable for applications where moderate capacitance values and compact board real estate are both important considerations. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuits, serving critical functions in power distribution, signal coupling, filtering, and energy storage across a wide range of industrial and commercial applications. The "682" designation in the part number indicates the capacitance value in picofarad units, typical of AVX's naming convention for their standard capacitor lines. This mid-range capacitance makes the part applicable to general-purpose filtering and decoupling tasks rather than bulk energy storage roles. The MAT2A suffix denotes the specific dielectric material and performance classification of this capacitor. AVX employs this designation system to distinguish between different dielectric formulations, each offering distinct characteristics in terms of capacitance stability, voltage rating, temperature behavior, and frequency response. Engineers selecting components from this family need to understand that ceramic capacitors exhibit capacitance variation across temperature ranges and applied voltage levels, with different dielectric classes offering trade-offs between stability and capacitance density. Engineers commonly specify AVX MLCCs in this package size for applications including power supply circuits, signal path filtering in amplifiers and data acquisition systems, RF circuit tuning, industrial control boards, and telecommunications equipment. The 1210 package strikes a practical balance—larger than smaller packages like 0805, allowing for higher capacitance values and better voltage ratings, yet still compact enough for high-density board layouts where space optimization matters. Selection of this particular part over alternatives would typically depend on matching the exact capacitance value requirement, voltage rating specification, and temperature stability characteristics needed for a specific circuit design. Engineers working with AVX components benefit from consistent quality, wide availability through distribution channels, and reliable performance in demanding industrial environments. When designing circuits requiring this specific capacitance and package combination, the 12105C682MAT2A provides a dependable solution backed by established manufacturing standards and technical support resources common to AVX's component portfolio.
