1825CA123JAT1A

The 1825CA123JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established suppliers of passive electronic components. This part belongs to the 1825 package family, which refers to its physical dimensions in the metric system—a surface-mount form factor commonly used in compact electronics where space efficiency is critical. Multilayer ceramic capacitors like this one are fundamental passive components found in virtually every modern electronic device. They function as energy storage elements, signal coupling/decoupling components, and filtering devices in analog and digital circuits. The ceramic dielectric material used in these capacitors provides stable performance across a range of operating conditions, making them suitable for applications where reliability and consistency are important. The "CA" designation within this part number indicates this capacitor belongs to AVX's general-purpose or standard ceramic capacitor line, designed for broad industrial and commercial applications rather than specialized high-reliability or high-performance segments. Engineers typically encounter these capacitors in power supply circuits, signal conditioning stages, impedance matching networks, and noise filtering applications across consumer electronics, industrial control systems, automotive electronics, telecommunications equipment, and computer hardware. The 1825 package size represents a popular choice for designers balancing component density with ease of manufacturing and repair. This size is substantially smaller than through-hole equivalents, allowing engineers to design more compact PCBs while maintaining manual rework capability if needed during assembly or field service. AVX's ceramic capacitor families are known for consistent manufacturing quality and widespread availability, which factors into design decisions. Engineers often specify parts from established manufacturers like AVX when the application requires proven reliability, when long-term availability is a concern, or when the design baseline has been validated with a particular manufacturer's process characteristics. The standardization of the 1825 package across multiple manufacturers also provides some design flexibility if supply constraints emerge. These capacitors work across a broad temperature range suitable for indoor and outdoor industrial environments. The ceramic dielectric composition affects characteristics like capacitance stability with temperature, frequency response, and voltage coefficient—factors that influence which specific part number engineers select for particular circuit requirements. For designers evaluating alternatives, considerations typically include the specific capacitance value, voltage rating, tolerance class, and the particular dielectric material's performance characteristics. AVX's broad portfolio within the 1825 package family allows engineers to select the exact electrical characteristics needed without changing package specifications, simplifying layout and assembly processes.
