1808AC102MAT1A

The 1808AC102MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part number designates a capacitor in the 1808 case size, which corresponds to metric dimensions and represents a medium-sized surface-mount package commonly used in modern electronics. Multilayer ceramic capacitors are fundamental passive components found in virtually every type of electronic equipment. They function to store electrical charge, filter noise, stabilize voltage supplies, and couple or decouple signals in circuits. The 1808 package strikes a balance between component size and capacitance value, making it suitable for applications where space is constrained but reasonable capacitance is needed. The alphanumeric suffix in this part number indicates specific electrical and material characteristics. AVX's designation system embeds information about the capacitance value, voltage rating, temperature coefficient, and dielectric material composition. The AC designation within the part number typically relates to the capacitor's dielectric type and performance class, which determines its suitability for different temperature ranges and operating conditions. This component is widely specified in industrial electronics, telecommunications equipment, power management circuits, consumer electronics, and automotive applications. Engineers select MLCCs like this part for bulk capacitance in power supply decoupling networks, signal filtering, and energy storage in DC-DC converters. The 1808 size is particularly popular in designs where engineers need to balance board space constraints against the requirement for multiple capacitors of modest capacitance values. Engineers choosing the 1808AC102MAT1A over alternatives would typically be considering factors such as AVX's reputation for reliability, the specific electrical characteristics embedded in the part number, compatibility with existing circuit designs, and qualification requirements for their application. Industrial and automotive buyers often prefer capacitors from established manufacturers with documented performance history and consistent quality standards. The surface-mount package format allows for automated assembly using standard pick-and-place equipment, reducing manufacturing costs compared to through-hole alternatives. The small physical footprint enables high-density circuit board layouts, important for modern compact equipment designs. When sourcing this component, engineers should verify that the specific electrical parameters—capacitance value, rated voltage, and temperature characteristics—match their circuit requirements. AVX maintains detailed technical documentation for their product lines, and cross-referencing with application requirements ensures proper performance and reliability in the final system.
