B82432T1472K – EPCOS

Overview

The EPCOS B82432T1472K is a 4.7 µH wirewound drum core inductor designed for demanding signal and power applications. Its primary function is energy storage and filtering, characterized by a robust 800 mA current rating and a low 220 mΩ DC resistance, crucial for minimizing power dissipation in high-current paths. A key design consideration for unshielded inductors like this is their susceptibility to electromagnetic interference (EMI) from adjacent components or their own radiated fields; careful layout and shielding strategies are paramount to maintain signal integrity and prevent unwanted coupling in sensitive circuits.
