180 µH at 175 mA with saturation headroom
The LPS3015-184MRC: Rated inductance is 180 µH ±20% at 100 kHz test frequency. The continuous DC current rating is 175 mA, while the saturation current (Isat) is 170 mA — the two values are nearly equal, so the inductor saturates just above the rated current. In a power-supply output filter or a DC-DC converter, the peak inductor current must stay below 170 mA to avoid a hard roll-off in inductance. Maximum DC resistance is 8.6 Ohm, which at 175 mA produces a copper loss of roughly 260 mW — a meaningful fraction of the inductor's self-heating budget in a compact 2.95 mm × 2.95 mm footprint. The 1.50 mm seated height keeps it usable in low-profile card assemblies.
Temperature range and deployment context
Combined with the AEC-Q200 rating, this inductor is suited for engine-bay or transmission-control environments where the ambient temperature can reach 125°C. The self-resonant frequency is 7.5 MHz, so the useful inductive region extends into the low-MHz switching range typical of automotive DC-DC converters and EMI filter stages.
Shielded ferrite construction in a nonstandard footprint
The ferrite core is fully shielded, which contains the magnetic flux and reduces radiated EMI into adjacent circuitry — important in a dense automotive ECU layout where the inductor shares a 2.95 mm × 2.95 mm land pattern with sensitive analog or digital traces. The nonstandard package means the footprint is specific to the LPS3015 series; confirm the PCB land pattern against the Coilcraft drawing before layout sign-off.
