1812GA101KAT1A

The 1812GA101KAT1A is a multilayer ceramic capacitor manufactured by AVX, designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the GA series of AVX capacitors, which are widely specified in industrial, consumer, and telecommunications equipment where reliable performance and compact size are essential. Multilayer ceramic capacitors (MLCCs) like this model function as energy storage devices and AC/DC filters in power supply circuits, signal conditioning networks, and high-frequency applications. The 1812 designation refers to the component's physical package size, indicating a surface-mount device with dimensions of 0.18 by 0.12 inches (4.5 x 3.2 mm). This compact footprint makes it ideal for dense PCB layouts while maintaining robust electrical performance, a key reason engineers select 1812-sized capacitors for space-constrained designs. The GA series represents AVX's mid-range ceramic capacitor offering, commonly used in applications requiring stable capacitance across operating conditions without the premium performance specifications of specialized military or aerospace-grade alternatives. These capacitors are particularly popular in consumer electronics, industrial control systems, power management circuits, and general RF/microwave applications where cost-effectiveness and proven reliability are priorities. Multilayer ceramic capacitors in this size and series typically deliver excellent high-frequency characteristics with low equivalent series resistance (ESR) and equivalent series inductance (ESL), making them suitable for bypass and decoupling functions in digital logic circuits and power distribution networks. The 1812 package also offers improved thermal properties compared to smaller packages, benefiting applications where component heat dissipation is a design consideration. Engineers often specify the 1812GA101KAT1A over smaller ceramic capacitors when circuit performance requires larger capacitance values, better voltage handling, or enhanced current-carrying capability. Conversely, designers may choose this exact part over larger packages when space savings and cost reduction are competing priorities. The GA series provides a practical middle ground in AVX's capacitor portfolio, offering proven performance in mainstream industrial and commercial applications without requiring specialized material systems or extended lead times. This surface-mount component is compatible with standard automated assembly processes and standard soldering profiles used in modern electronics manufacturing. Its widespread adoption across various industries reflects the reliability and versatility of ceramic capacitor technology in contemporary circuit design.
