1812CA562JAT3A

The 1812CA562JAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components. This capacitor belongs to the 1812 package family, which refers to its physical dimensions in the metric system (approximately 4.5mm × 3.2mm). The 1812 package size represents a mid-range footprint, larger than smaller 0603 or 0805 packages but more compact than larger 1825 or 1840 variants, making it suitable for space-constrained designs that still require reasonable capacitance values. As a ceramic capacitor, this component uses a ceramic dielectric material sandwiched between metal electrodes to store electrical charge. MLLCs are fundamental building blocks in modern electronics, widely used for decoupling, filtering, and energy storage across countless applications. The CA series designation indicates this is part of AVX's general-purpose ceramic capacitor line, typically designed for use in standard industrial and commercial applications rather than specialized high-reliability or automotive-grade segments. The specific part number suffix "562" relates to the capacitance value designation. While the exact value should be confirmed through the manufacturer's documentation, this numbering follows standard IPC conventions where the digits encode the capacitance rating. These mid-range capacitance values are commonly found in power supply circuits, signal filtering networks, and bypass applications where moderate capacitance values are needed. Engineers typically specify the 1812CA562JAT3A for applications requiring a balance between board space, performance, and cost. This part is frequently encountered in industrial control equipment, audio amplifiers, power management circuits, and general-purpose consumer electronics. The 1812 package provides adequate volumetric efficiency compared to smaller components while remaining easy to hand-solder or machine-place during manufacturing. The AVX CA series is known for consistent performance across standard temperature ranges relevant to most industrial applications. These capacitors are reliable workhorses suitable for non-critical filtering and decoupling roles where premium specifications like extreme temperature stability or exceptionally low ESR are not required. When considering alternatives, engineers might compare this part against other 1812-package MLLCs from competing manufacturers, or evaluate whether a different package size could meet their circuit requirements. The specific dielectric type and voltage rating of this part (which should be verified against official specifications) will determine its suitability for particular circuit voltage levels and temperature conditions. For designs with stringent requirements, specialized MLCC variants with enhanced characteristics may be more appropriate.
