The shielded construction contains the magnetic flux, reducing radiated EMI into nearby traces or components — a practical advantage when the inductor sits next to a switching regulator or a sensitive analog front-end. ## Footprint and integration constraints Surface-mount on a nonstandard case — the pad layout matches the Coilcraft LPS4018 footprint; the 5.9 Ω maximum DCR means the I²R loss at 170 mA is about 170 mW, so the inductor runs warm but stays within the ferrite core's temperature rating under normal convection. The self-resonant frequency of 5.5 MHz sets the upper limit for the switching frequency in a buck or boost converter — above that the inductive impedance drops and the part behaves capacitively.","metaTitle":"Coilcraft LPS4018-334MRC Shielded Power Inductor, 330 µH","metaDescription":"Coilcraft LPS4018-334MRC shielded drum-core inductor, 330 µH ±20%, 170 mA rated, 180 mA saturation, AEC-Q200 qualified.
