08055C472KAT2A – AVX

Overview

The KYOCERA AVX 08055C472KAT2A is a high-performance multilayer ceramic capacitor (MLCC) designed for robust signal integrity and filtering applications. Its X7R dielectric offers a stable capacitance across a wide temperature range (-55°C to +125°C), making it suitable for demanding environments. A critical design consideration for X7R dielectrics, however, is their susceptibility to capacitance change with applied DC bias; engineers must account for this derating to ensure predictable circuit behavior, especially in voltage-sensitive analog signal paths or power supply decoupling where precise impedance is paramount.
