1812PC104KAT1A

The 1812PC104KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This component belongs to the 1812 package family, which denotes its physical dimensions in imperial format (0.180 inches by 0.120 inches), making it a surface-mount device suitable for automated assembly processes. Multilayer ceramic capacitors are fundamental passive components used across virtually every electronic circuit board to perform energy storage, filtering, decoupling, and AC coupling functions. The 1812 package size represents a mid-range offering that balances capacitance density with ease of handling and placement on modern PCBs. This particular part is designed for general-purpose applications where designers need reliable capacitive performance without requiring extreme voltage ratings or specialized material properties. The "PC" designation in AVX's naming convention typically indicates a general-purpose ceramic capacitor formulation, while the alphanumeric suffix provides manufacturing and specification details. Engineers working with industrial electronics, consumer devices, telecommunications equipment, and automotive circuits frequently specify 1812 package capacitors when they require sufficient capacitance in a compact footprint while maintaining cost-effectiveness and broad supplier availability. The 1812 package format offers several practical advantages in modern electronics manufacturing. The larger surface area compared to smaller packages like 0805 or 0603 makes placement and rework more manageable during production and repair. Additionally, larger packages typically exhibit better mechanical reliability and lower ESR (equivalent series resistance) characteristics relative to their miniature counterparts, which can be important in power distribution networks and high-frequency filtering applications. AVX's MLCC products are recognized throughout the industry for consistent quality and performance across commercial and industrial temperature ranges. Engineers specify this part number when they need a capacitor that delivers predictable behavior across typical operating conditions without premium features or costs associated with specialized ceramic formulations. Common applications for 1812 multilayer ceramic capacitors include power supply decoupling, signal coupling and blocking, noise filtering, and timing circuits. They are widely used in automotive electronics, industrial control systems, communications infrastructure, and consumer electronics where reliability and performance must be maintained across varying environmental conditions. When selecting between similar capacitors, engineers consider the specific ceramic formulation, voltage rating, capacitance tolerance, and temperature stability required by their circuit. The 1812PC104KAT1A represents AVX's standard offering in this popular package size, making it a pragmatic choice for applications requiring dependable capacitive performance with excellent component availability and manufacturing support.
