15 µH shielded inductor for DC-DC input/output filters
The Coilcraft LPS4018-153MRC is a shielded drum core inductor in the LPS4018 series, delivering 15 µH ±20% inductance with an 800 mA continuous current rating and an 860 mA saturation current floor. The 260 mOhm max DCR keeps conduction losses manageable for point-of-load regulators in the 1–3 W range. The shielded ferrite core contains the magnetic field, reducing EMI coupling to nearby traces in a dense layout.
The strip-pack format suits automated pick-and-place assembly; confirm the reel quantity with your distributor if tape-and-reel is required for the line. The self-resonant frequency of 32 MHz places the inductor well above the switching frequency of most buck converters (typically 300 kHz–2 MHz), so the inductive impedance dominates and parasitic capacitance does not degrade filtering performance.
