100 µH shielded drum core for DC-DC filter stages
The Coilcraft LPS5015-104MRC is a 100 µH shielded drum-core inductor in the LPS5015 series, rated for 300 mA continuous current with a matching 300 mA saturation current. Shielding is specified, so the flux is contained within the ferrite core — adjacent power-stage traces or a nearby GND plane see minimal eddy-current coupling. The 12 MHz self-resonant frequency means the inductor behaves as an inductor well above the switching frequency of most buck or boost converters running 200 kHz to 2 MHz; above SRF the impedance turns capacitive and the filter response collapses.
Footprint and board-fit constraints
The nonstandard case code means the pad layout is specific to the part — there is no industry-standard 5 mm square footprint; the recommended PCB land pattern from the Coilcraft drawing should be used rather than a generic 5 mm pad. The ferrite core is brittle; excessive board flex during depanelization or rework can crack the drum, so a support fixture under the inductor during singulation is worth the setup time.
