120 µH shielded ferrite-core inductor
The Coilcraft LPS3015-124MRC is a 120 µH shielded power inductor in the LPS3015 series, built on a ferrite core and qualified to AEC-Q200. Rated for 230 mA continuous with a saturation current floor of 220 mA, the 4.65 Ohm max DCR sets the I²R loss budget for a 2.95 mm square, 1.50 mm tall surface-mount package.
AEC-Q200 and 125 °C ceiling
That 125 °C upper limit covers under-hood and engine-bay ambient without derating the current below the 230 mA mark.
Self-resonant frequency and test conditions
Self-resonant frequency is 9 MHz — above that the inductor behaves capacitively, so the useful filtering range stops well below 9 MHz. Inductance is tested at 100 kHz, the standard power-inductor test frequency for this value range.
