1 µH shielded drum core for power rail filtering
The Coilcraft LPS5015-102MRC is a 1 µH shielded drum-core inductor rated for 1.9 A continuous with a saturation current floor of 3.6 A — the headroom between rated and saturation means the core holds its inductance well past the nominal load, so a DC-DC converter drawing 1.5 A still sees the full 1 µH at the switching edge.
Shielded construction and self-resonant ceiling
The ferrite core and full magnetic shield contain the flux within the package — adjacent traces on a dense 4-layer board see minimal coupling, which matters when the inductor sits next to a sensitive analog converter or a high-impedance feedback node. The self-resonant frequency of 183 MHz is well above the switching band of most POL converters (300 kHz to 2 MHz typical), so the inductor behaves as a pure inductive element across the operating bandwidth with no parasitic capacitive roll-off.
