Its 200 mOhm maximum DC resistance keeps conduction losses manageable at rated current, while the unshielded construction means the magnetic field extends beyond the part — board layout should keep sensitive traces and other inductors clear of the flux path. ## 1812 footprint and self-resonant frequency The self-resonant frequency of 120 MHz defines the upper usable band — above that point the component behaves capacitively, so for filtering or DC-DC converter applications keep the switching frequency well below 120 MHz to stay in the inductive region. ## Active production, sourced per RFQ Pricing and lead time are confirmed at quote time against the requested quantity — availability is verified through independent and franchised distribution channels.","metaTitle":"Murata LQH43NN1R0M03L Drum Core Inductor, 1 µH, 500 mA","metaDescription":"Murata LQH43NN1R0M03L wirewound drum core inductor, 1 µH ±20%, 500 mA, 200 mOhm DCR, 1812 SMD.
