B82464G4682M – EPCOS

Overview

The EPCOS B82464G4682M is a shielded, wirewound power inductor designed for demanding DC-DC converter applications, offering a nominal inductance of 6.8 µH. Its robust ferrite core and high saturation current of 4.99 A are critical for maintaining stable energy storage under significant load transients, a key consideration in automotive power management where component reliability is paramount. While its 20% inductance tolerance is acceptable for many power filtering tasks, designers must account for this variability in their control loop compensation to ensure optimal transient response and prevent potential instability, especially in systems with tight ripple requirements.
