Its 750 mA continuous current rating and 350 mOhm max DCR define the DC loss budget for the rail — at full rated current the copper loss is roughly 0.2 W, which the 5×5 mm package must dissipate into the board copper. Saturation current is 1 A, the hard ceiling where inductance drops by the test-defined amount — stay below this to keep the ripple current under control in a buck converter. ## Shielding and temperature range for dense boards The shielded construction contains the magnetic field within the ferrite core, reducing EMI coupling to adjacent traces and components — useful when the inductor sits near a sensitive analog rail or RF section. Self-resonant frequency is 40 MHz, well above typical 100 kHz to 2 MHz switching converters — the inductor behaves as a pure inductance in that band, with parasitic capacitance only becoming relevant above 10 MHz. ## Footprint and rework considerations No exposed pad or orientation marking beyond the standard drum-core asymmetry — verify the pad layout against the Coilcraft drawing before stencil release; the part is symmetrical in the X-Y plane, so reverse mounting is electrically identical but visually ambiguous for inspection.","metaTitle":"Coilcraft LPS5015-123MRC Shielded Drum Core Inductor, 12 µH","metaDescription":"Coilcraft LPS5015-123MRC shielded drum core inductor, 12 µH ±20%, 750 mA, 350 mOhm DCR.
