1812SC123KAT1A

The 1812SC123KAT1A is a multilayer ceramic capacitor manufactured by AVX in the widely-used 1812 surface-mount package format. This component belongs to the general category of fixed capacitors and serves as a fundamental building block in electronic circuit design across numerous industrial and consumer applications. Multilayer ceramic capacitors (MLCCs) like this part are utilized primarily for energy storage, filtering, and signal coupling functions in power supplies, audio circuits, RF applications, and digital signal processing equipment. The 1812 package designation refers to the physical dimensions of the component, making it a mid-sized surface-mount capacitor suitable for applications requiring moderate capacitance values in a compact footprint. This size category is particularly popular in industrial control systems, telecommunications infrastructure, medical instrumentation, and automotive electronics where board space is moderately constrained but component performance and reliability are critical. AVX is recognized within the electronics industry for manufacturing capacitors that meet stringent quality standards required by industrial and professional equipment manufacturers. The SC series designation typically indicates this capacitor is optimized for standard commercial or industrial temperature ranges and general-purpose filtering applications. Multilayer ceramic capacitors in this package size are known for their stable performance across temperature variations, relatively low equivalent series resistance (ESR), and excellent frequency response characteristics compared to single-layer alternatives. Engineers typically specify parts from this family when designing circuits that require reliable capacitive performance in filtering power supply rails, decoupling high-frequency noise, or providing stable timing references. The 1812 package offers an advantageous balance between component size and electrical performance—larger than smaller packages like 0805 or 1206, yet still mountable on standard automated assembly equipment. This makes it a practical choice for designs where board density is important but performance cannot be compromised. The specific part number designation 123KAT1A contains information regarding the capacitive value and rated voltage characteristics specific to AVX's part numbering system. Engineers selecting this exact component would typically do so based on circuit requirements matching the electrical specifications this part number represents, along with the reliability track record and quality certifications that AVX components provide for demanding industrial and professional applications. For precise electrical specifications, operating ranges, and performance data for this specific part number, consultation with AVX's technical documentation is recommended to ensure proper circuit design and component selection for your application requirements.
