1812HA820JAT1A

The 1812HA820JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, part of the company's established film capacitor product line. This component features a 1812 case size (imperial designation), which translates to physical dimensions of approximately 18mm by 12mm, making it suitable for applications where moderate component density and space efficiency are required on printed circuit boards. Multilayer ceramic capacitors of this type are fundamental passive components used across virtually every segment of industrial electronics. They serve critical functions including signal coupling and decoupling, power supply filtering, noise suppression, and high-frequency signal conditioning. The 1812 package size strikes a practical balance between capacitance capability and PCB real estate consumption, making it popular in applications where designers need higher capacitance values than smaller packages offer, but space constraints prevent using larger formats. AVX's capacitor offerings in this category are engineered for reliability in demanding industrial environments. Components designated with the "HA" designation within the 1812 package family typically target applications requiring stable performance across temperature variations and extended operational lifespans. These capacitors are commonly found in power distribution systems, industrial control equipment, telecommunications infrastructure, automotive electronics, and renewable energy converters where robustness and consistent electrical performance are essential. The 1812 package size provides several practical advantages for circuit designers. It offers substantially higher volumetric efficiency than smaller packages, allowing engineers to achieve necessary filtering and energy storage functions without multiplying component counts. This reduces assembly complexity and improves board-level reliability by minimizing solder joints and interconnection points. Additionally, the larger format provides better thermal dissipation characteristics compared to significantly smaller alternatives, which can be important in applications with elevated operating temperatures or high ripple current conditions. Engineers typically specify this exact part number when their circuit design calculations require the specific capacitance value indicated in the part designation, combined with the mechanical constraints of the 1812 package and AVX's particular dielectric formulation and manufacturing quality standards. Industrial buyers often prefer established manufacturers like AVX for mission-critical applications where component failure could result in system downtime or safety concerns, justifying the selection of this particular component over lower-cost alternatives from less established suppliers. This component is suitable for applications ranging from industrial power supplies and motor drives to test equipment, factory automation controllers, and distributed renewable energy systems where proven performance and consistent availability are priorities.
