1808HA470MAT1A

# 1808HA470MAT1A - AVX Multilayer Ceramic Capacitor The 1808HA470MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized producer of passive electronic components for industrial and commercial applications. This part belongs to the 1808 package family, which refers to its physical dimensions in the metric 18.0mm × 8.0mm form factor, making it a larger-format surface-mount capacitor suitable for applications requiring moderate capacitance values in a compact footprint. Multilayer ceramic capacitors are fundamental components in modern electronics, serving primarily as energy storage and signal filtering elements in power supplies, amplifiers, switching circuits, and data acquisition systems. The 1808 package size positions this capacitor in the mid-range category, offering a balance between capacitance density and ease of assembly on industrial PCBs. This particular part is designed for applications where engineers need reliable, cost-effective filtering or decoupling without requiring the space demands of larger component packages. The designation "HA" within the part number typically indicates the specific dielectric material and performance characteristics of the capacitor, which influences its voltage rating, temperature stability, and frequency response. AVX's product line spans various dielectric classes to serve different application requirements, from high-capacitance, lower-voltage designs to lower-capacitance, higher-voltage variants. Engineers typically specify AVX MLCCs in this package size for industrial control systems, telecommunications equipment, medical instrumentation, and automotive electronics where environmental reliability and consistent electrical performance are essential. The 1808 format provides sufficient capacitance for bulk filtering and decoupling applications while remaining compatible with standard surface-mount assembly processes used in high-volume manufacturing environments. The choice of an AVX component from this family reflects the manufacturer's reputation for consistent quality, established supply chain presence, and compliance with industrial standards. For applications requiring specific voltage ratings, temperature coefficients, or ESR characteristics, engineers often cross-reference multiple capacitor families to identify the best performing alternative. The 1808HA470MAT1A serves as a standard reference point within AVX's MLCC portfolio, making it identifiable and replaceable across multiple production batches and procurement cycles. This capacitor is suitable for designers working with industrial control boards, power management circuits, and signal conditioning applications where reliable passive component performance directly impacts overall system stability and longevity.
