The ferrite core and shielded construction keep radiated noise low, which matters when the inductor sits near sensitive analog or RF stages on the same board. ## Current and DCR — what drives the fit Rated for 700 mA continuous with a saturation current of 780 mA, the part handles the full DC bias without the inductance dropping off the datasheet curve — the margin between the two figures is tight, so a load that peaks near 780 mA pushes the core into saturation. Maximum DC resistance is 270 mOhm — at 700 mA the I²R loss is about 132 mW, which the 1.80 mm profile must dissipate into the board copper.","metaTitle":"Coilcraft LPS4018-183MRC 18 µH Shielded Inductor, AEC-Q200","metaDescription":"Coilcraft LPS4018-183MRC 18 µH shielded drum core inductor, 700 mA, 270 mOhm DCR, AEC-Q200 rated.
