12101A472KAT2A

# AVX 12101A472KAT2A Product Description The AVX 12101A472KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and energy storage applications across industrial and commercial electronics. This component belongs to AVX's established capacitor product line, manufactured with ceramic dielectric technology that provides stable performance across a wide range of operating conditions. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronic circuits. They function by storing electrical energy in an electric field between multiple thin ceramic layers, making them essential for power supply filtering, signal coupling and decoupling, bypass filtering near integrated circuits, and EMI suppression. Due to their small physical size relative to their capacitive value, MLCCs enable compact circuit board layouts while maintaining reliable performance. The 12101A472KAT2A designation indicates this is a specific formulation within AVX's capacitor portfolio. The part number structure contains information about the component's rated characteristics and packaging format. This capacitor is housed in a surface-mount package suitable for automated assembly on printed circuit boards, which is the standard for modern industrial and consumer electronics manufacturing. Engineers typically specify AVX MLCCs for their reputation for reliability, temperature stability, and consistent performance over extended product lifecycles. AVX capacitors are widely used in power management circuits, industrial control systems, telecommunications equipment, medical devices, automotive electronics, and consumer appliances where ceramic capacitor technology is the preferred choice. The brand is recognized in the industry for quality control and adherence to international standards. The specific selection of this part number over alternatives would typically be driven by several factors: the exact capacitance value required by the circuit design, the voltage rating needed for the application, physical space constraints on the PCB, temperature operating range specifications, and the frequency characteristics demanded by the circuit. Different manufacturers and product lines offer varying trade-offs between capacitance stability across temperature ranges (known as temperature coefficient), voltage derating characteristics, and cost. When designing circuits requiring capacitive elements for filtering or energy storage, engineers consult component datasheets to match the part's electrical properties with circuit requirements. For high-reliability applications, the manufacturer's quality certifications and long-term production availability are also significant selection criteria. AVX maintains established supply chains and documentation standards that support engineering teams in applications ranging from military and aerospace contexts down to standard industrial equipment where component traceability and consistency are important.
