B82464G4224M – EPCOS

Overview

The EPCOS B82464G4224M is a shielded, wirewound drum core inductor designed for robust energy storage and filtering applications. Its critical operational characteristic is the precise 220 µH inductance value, essential for maintaining stable circuit operation. A key design consideration for this component is managing the trade-off between its high saturation current (750mA) and its relatively low DC resistance (440mΩ max); exceeding saturation current can lead to significant inductance drop, impacting filtering effectiveness, while a lower DCR is crucial for minimizing power dissipation in high-current designs.
