1 mH shielded drum core in a 5×5 mm footprint
The LPS5015-105MRC: Rated at 100 mA with an 80 mA saturation current, this part suits DC-DC converter output filters and power-supply rail smoothing where the DC bias stays below the saturation knee. The ferrite core material and full magnetic shield keep flux contained, reducing radiated EMI in tight board layouts near sensitive analog or RF stages.
Parametric limits that govern the design
Self-resonant frequency is 3.2 MHz; above this the inductive impedance rolls off and the component behaves capacitively, so the switching frequency of the downstream converter should stay well below 3.2 MHz. Inductance is tested at 100 kHz, the standard measurement frequency for power inductors in this value range.
