1812WC471MAT3A

The 1812WC471MAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading producer of passive electronic components. This part belongs to the 1812 package family, which refers to its physical dimensions in the metric system—indicating a surface-mount component with a footprint suitable for automated assembly on printed circuit boards. Multilayer ceramic capacitors like this are among the most widely used passive components in modern electronics. They function to store and release electrical energy, filter noise, couple or decouple signals, and stabilize voltage supplies across countless applications. The ceramic dielectric material provides reliable performance across a broad range of frequencies and environmental conditions, making MLCCs ideal for both consumer and industrial equipment. The 1812 package size represents a mid-range capacitor footprint, offering a practical balance between capacitance value, voltage rating, and physical board space. This makes it suitable for applications where designers need reasonable capacitance without consuming excessive real estate on the PCB. The "WC" designation within the part number indicates this capacitor is part of AVX's general-purpose ceramic capacitor family, typically engineered for standard industrial and commercial applications rather than specialized high-reliability or high-temperature environments. Common application areas for 1812 package MLCCs include power supply filtering, signal coupling in audio and RF circuits, timing circuits, decoupling near integrated circuit power pins, and noise suppression in switching power supplies. They are frequently found in consumer electronics, telecommunications equipment, automotive systems, industrial control boards, and various embedded computing applications. Engineers typically specify this exact part number when they require a capacitor with the specific electrical characteristics encoded in the designation—particularly the capacitance value and voltage rating that the "471" and other code elements represent. The AVX brand heritage and manufacturing standards associated with this part make it a reliable choice where consistency and performance predictability matter across production runs. The surface-mount 1812 package allows for efficient automated placement during board assembly, reducing manufacturing costs compared to through-hole alternatives while maintaining robust mechanical connection to the PCB. This combination of proven ceramic dielectric technology, established package standardization, and manufacturer reliability makes the 1812WC471MAT3A a dependable component choice for designers specifying passive filtering and energy storage solutions in their circuit designs.
