1812SA390MAT1A

# 1812SA390MAT1A Product Description The 1812SA390MAT1A is a surface-mount ceramic capacitor manufactured by AVX, featuring an 1812 case size designation. This component belongs to the SA series family, which represents a general-purpose multilayer ceramic capacitor (MLCC) line designed for broad industrial and commercial applications. In the 1812 package format, this capacitor offers a compact footprint suitable for high-density circuit board layouts while maintaining reasonable capacitance and voltage handling capabilities. The SA series is engineered as a cost-effective solution for standard filtering, coupling, decoupling, and bypass applications across a wide range of electronic equipment and industrial control systems. Ceramic capacitors of this type are widely used in power supply circuits, where they provide high-frequency noise filtering and voltage stabilization. They appear frequently in audio equipment, telecommunications hardware, industrial automation controllers, and general-purpose consumer electronics. The 1812 package size represents a middle ground in the capacitor landscape, offering better volumetric efficiency than larger through-hole designs while providing adequate current-handling characteristics for many mainstream applications. The SA series from AVX is known for combining reliable performance with cost efficiency, making it a popular choice for original equipment manufacturers and contract assemblers working on budget-conscious projects where premium performance specifications are not required. These capacitors use standard ceramic dielectric materials and construction methods that have been proven in the field for decades. Engineers might specify this exact part number when designing equipment that requires a proven, readily available general-purpose capacitor with good thermal stability and consistent performance across typical operating temperature ranges. The combination of established manufacturing processes, widespread compatibility with standard pick-and-place equipment, and proven field reliability makes this part number attractive for mid-volume production runs where supply chain predictability matters as much as performance metrics. The 1812 format also provides practical advantages during assembly and repair. The package size allows for straightforward solder reflow processing while remaining accessible for rework or hand soldering if needed. The capacitor can interface with standard PCB trace widths and via patterns without requiring specialized design considerations. For engineers evaluating alternatives, this part represents the mainstream industrial choice when application requirements do not demand specialized characteristics such as extreme temperature ranges, ultra-low ESR performance, or high-voltage operation. Its prevalence in the market and established supply channels make it a low-risk selection for standard circuit design applications.
