GRM21BR71H473KA01L – MURATA

Overview

The Murata GRM21BR71H473KA01L is a 0.047 µF, 50V ceramic capacitor featuring an X7R dielectric, designed for general-purpose surface mount applications. Its primary function is energy storage and filtering, crucial for stabilizing voltage rails and decoupling noise in digital and analog circuits. A key design consideration for X7R dielectrics is their capacitance shift with applied DC bias and temperature; while offering a wider operating range than NP0, designers must account for this non-linearity to ensure predictable circuit performance, especially in applications with significant voltage swings or thermal variations.
