Overview
The SCHAFFNER RI403PC is a robust fixed inductor designed for efficient energy storage and filtering in power electronics circuits. Its primary function is to impede changes in current, a critical characteristic for smoothing rectified AC or stabilizing switching currents. A key design consideration for inductors of this type is the trade-off between inductance value and saturation current; while the 1.8 mH rating provides significant filtering capability, designers must carefully manage operating currents to prevent core saturation, which drastically reduces effective inductance and compromises performance. This unshielded radial component, with its 3A current rating and 105mΩ DCR, offers a balance of performance and cost-effectiveness for numerous power management applications.
Key Features
