12101A392JAT2A

The AVX 12101A392JAT2A is a multilayer ceramic capacitor (MLCC) designed for use in a wide range of electronic applications requiring compact, reliable energy storage and filtering. As a component from AVX's established capacitor portfolio, this part represents the type of fixed capacitor technology commonly found in consumer electronics, industrial control systems, telecommunications equipment, and power supply circuits. Multilayer ceramic capacitors like this model function as passive components that store electrical charge and filter high-frequency noise from power and signal lines. They are essential in modern circuit design for applications such as decoupling power supply pins on integrated circuits, filtering switching noise in converter topologies, coupling and bypassing signals in audio and RF circuits, and stabilizing voltage rails in digital logic systems. The part number structure indicates this is a standard surface-mount component in AVX's comprehensive MLCC lineup. AVX manufactures these capacitors in various dielectric grades and case sizes to serve different performance requirements, ranging from general-purpose applications to specialized uses demanding higher voltage ratings, improved temperature stability, or enhanced capacitance density. Engineers typically specify a particular AVX MLCC part number based on several critical factors. The case size affects board layout density and mechanical constraints in compact designs. The dielectric material composition determines the capacitance value, voltage rating, temperature coefficient behavior, and how the capacitance changes under applied bias voltage—factors that significantly impact circuit performance and reliability. Different dielectric grades trade off capacitance density against stability; for instance, some formulations maintain more consistent capacitance across temperature ranges and voltage conditions, while others offer higher capacitance per unit volume. In industrial and engineering applications, selecting the correct MLCC becomes particularly important for mission-critical systems. Factors such as operating temperature range, moisture absorption characteristics, and long-term reliability under thermal cycling all influence component choice. AVX MLCCs are widely specified in industrial equipment because they combine proven reliability with the cost-effectiveness necessary for high-volume manufacturing. This component would be selected when a designer requires a dependable, space-efficient capacitor for filtering, coupling, or energy storage in electronic assemblies. The specific case size and electrical characteristics make it suitable for standard PCB assembly processes, whether using automated pick-and-place equipment or manual assembly methods common in industrial manufacturing environments.
