12101C823JAT2A

The AVX 12101C823JAT2A is a multilayer ceramic capacitor (MLCC) designed for demanding industrial and commercial electronics applications. This component represents a core passive element found in power supplies, filtering networks, signal conditioning circuits, and various embedded systems where reliable energy storage and AC coupling are critical. Multilayer ceramic capacitors like this part are constructed from alternating layers of ceramic dielectric material and metal electrodes, compressed into a compact package. This construction method enables manufacturers to achieve high capacitance values within small physical footprints, making them ideal for space-constrained modern electronics. The 12101C series from AVX is part of the company's established MLCC portfolio, recognized for consistent quality and reliable performance across commercial and industrial temperature ranges. This particular part number indicates a surface-mount device format, which is the overwhelming standard in modern board assembly. Surface-mount capacitors enable automated pick-and-place manufacturing, reducing assembly costs and improving production consistency compared to through-hole alternatives. Engineers typically specify surface-mount MLLCs when designing new products intended for volume production. AVX's capacitors in this family are commonly specified in switching power supply designs, where they function as bulk capacitors to stabilize voltage rails and suppress noise. They are also frequently used in analog signal processing circuits, decoupling applications near integrated circuits, and filtering stages in measurement instruments. The ceramic dielectric material provides stable capacitance across typical operating conditions while maintaining relatively flat frequency response characteristics. When selecting among competing MLCC options, engineers consider several factors beyond simple capacitance rating. Component size, voltage rating, temperature coefficient behavior, ESR (equivalent series resistance), and the manufacturer's track record for reliability all influence the decision. AVX parts are widely accepted in industrial settings due to their consistent performance and availability through established distribution channels. The specific construction and materials used in this series help ensure predictable behavior in applications ranging from consumer electronics to professional instrumentation. The ceramic chemistry, layer count, and electrode configuration determine each capacitor's electrical performance envelope. Different AVX MLCC series offer varying balances between capacitance density, voltage handling, and temperature stability. Engineers reviewing this part number would be evaluating it as a candidate for a specific circuit role where these performance characteristics align with their design requirements. Capacitors from established manufacturers like AVX provide documentation and reliability data that support qualification processes in regulated industries, making them preferable to generic alternatives in many professional applications.
