It is rated for 1.24 A continuous current with a DCR of 74.4 mOhm max, making it a fit for switching regulator output filters and power rail smoothing in space-constrained designs. ## Current handling and saturation margin Rated at 1.24 A continuous with a saturation current (Isat) of 1.7 A, the inductor offers a 37 % headroom above the rated current before inductance rolls off — the saturation point is the hard ceiling; the current rating is the thermal limit in free air. Self-resonant frequency of 100 MHz means the inductor behaves as an inductor well into the HF band, so it filters switching noise from a 1–2 MHz buck converter without parasitic capacitance dominating. ## Shielded construction and temperature range Shielded ferrite core contains the magnetic field — critical when the inductor sits next to a sensitive analog rail or RF section on the same board, as stray flux can couple into adjacent traces.","metaTitle":"Murata LQH3NPN1R0MGRL Shielded Wirewound Inductor, 1 µH","metaDescription":"Murata LQH3NPN1R0MGRL drum core wirewound inductor, 1 µH ±20%, shielded, 1.24 A, 74.4 mOhm DCR, 1212 package.
