12105A182JA14A

The AVX 12105A182JA14A is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications in industrial and commercial electronics. This component belongs to the 1210 case size family, a standard surface-mount package widely used in power distribution, signal conditioning, and filtering circuits across a broad range of equipment. Multilayer ceramic capacitors like this part are fundamental passive components used to store and release electrical charge. In practical applications, they serve critical roles including decoupling (removing noise from power supplies), coupling (passing AC signals while blocking DC), filtering (smoothing voltage ripples), and energy storage in switched-mode power supplies and audio amplifiers. The 1210 package strikes a balance between component density and capacitance value, making it popular in modern PCB layouts where space is constrained but reliable mid-range capacitance is required. The "182" portion of the part number indicates the capacitance value within AVX's standard coding scheme. The "JA14A" suffix provides information about the component's temperature characteristics, voltage rating, and dielectric material composition—factors that determine its operating range and reliability in specific thermal and electrical environments. AVX manufactures this part with their proprietary dielectric formulations, designed to maintain stable performance across the temperature ranges typical in industrial equipment, from standard operating conditions through more demanding thermal cycling scenarios. Engineers often specify this exact part number when designing circuits that require predictable, stable capacitive performance in a compact surface-mount form factor. The 1210 case size allows efficient use of PCB real estate compared to larger through-hole alternatives, while providing better mechanical stability on modern automated assembly lines than smaller 0805 or 0603 packages when higher capacitance values are needed. This capacitor would typically be found in power management sections, analog signal paths, or RF circuits in industrial automation equipment, test instrumentation, power conversion systems, and communications hardware. Its MLCC construction provides excellent frequency response, low equivalent series resistance (ESR), and cost-effective manufacturing, which collectively make it a reliable choice for OEM designers balancing performance requirements with manufacturing efficiency and cost considerations. Selecting the AVX 12105A182JA14A over alternatives ensures compatibility with existing designs, proven reliability in field applications, and consistent performance characteristics that engineers can depend on during product lifecycle management and design revisions.
