1812PC474MAT1A

The 1812PC474MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This component belongs to the popular 1812 package family, which denotes its physical dimensions in metric notation (approximately 4.5mm x 3.2mm x 2.5mm). Capacitors in this package size are widely used in industrial electronics, consumer devices, telecommunications equipment, and power management applications where moderate capacitance values and reasonable board space efficiency are required. Multilayer ceramic capacitors like this part are constructed from alternating layers of ceramic dielectric material and metal electrodes, which are fired together to create a monolithic structure. This construction method enables high volumetric efficiency and reliable performance across a broad temperature range. The 1812 package represents a mid-sized offering that balances capacitance density against ease of handling and automated assembly on modern production lines. The "PC" designation in the part number indicates this capacitor is from AVX's established PC series, which is designed for general-purpose applications requiring stable performance and good cost-effectiveness. These capacitors are commonly specified in filtering circuits, decoupling applications, timing networks, and signal conditioning stages throughout industrial control systems, measurement equipment, and automation hardware. Engineers frequently choose components from this series for applications where component reliability and long-term availability are priorities, given AVX's established market presence and consistent production volumes. The 1812 package size makes this capacitor suitable for both through-hole and surface-mount assembly, depending on the specific termination style of individual parts within the family. Its moderate size allows engineers to achieve desired capacitive values without consuming excessive board real estate, making it practical for space-constrained applications while remaining large enough to handle in manual assembly operations if needed. Typical reasons an engineer might select this exact part include compatibility with existing designs already qualified on AVX multilayer ceramic capacitors, the proven reliability of the PC series in field applications, established supply chain relationships with this manufacturer, and the component's balance of performance, size, and cost. The 1812 package also offers better high-frequency characteristics compared to larger packages while providing more capacitance options than smaller alternatives, making it a versatile choice for mid-range industrial applications.
