GRM31MR71E105KA01L – MURATA

Overview

The Murata GRM31MR71E105KA01L is a 1 µF, 25V ceramic capacitor featuring an X7R dielectric, critical for applications demanding stable capacitance over a moderate temperature range. While X7R offers a favorable balance between capacitance density and temperature stability compared to lower-class dielectrics, designers must account for its inherent voltage coefficient of capacitance (VCC). This means the effective capacitance can decrease significantly at higher applied voltages, a key consideration when sizing decoupling capacitors for sensitive analog circuits or when operating near the 25V limit.
