GRM155R71H472KA01D – MURATA

Overview

The Murata GRM155R71H472KA01D is a high-performance 4700 pF X7R multilayer ceramic capacitor (MLCC) designed for demanding SMT applications. Its primary function is stable energy storage and filtering across a wide temperature range, crucial for maintaining signal integrity. A key design consideration for X7R dielectrics, like this 50V rated component, is the inherent capacitance variation with applied DC bias and temperature, which engineers must account for in circuit design to avoid unexpected performance shifts, especially in sensitive analog front-ends.
