GRM31MR71E224KA01L – MURATA

Overview

The Murata GRM31MR71E224KA01L is a 0.22 µF, 25V ceramic capacitor featuring an X7R dielectric, designed for general-purpose surface-mount applications. Its primary function is to provide stable capacitance across a broad temperature range, crucial for filtering and decoupling in sensitive circuits. A key design consideration for X7R dielectrics, however, is their tendency for capacitance to decrease with applied DC voltage (DC bias), a factor engineers must account for to ensure adequate filtering margin in high-impedance or low-voltage rail applications.
