Rated for 940 mA continuous DC with a saturation current of 1.05 A, it handles the ripple current in a buck converter output stage without saturating under transient loads. Maximum DC resistance is 144 mOhm, which at rated current gives about 127 mW of I²R loss — a factor for thermal budget in a dense 1212 footprint. The self-resonant frequency of 30 MHz means it behaves as an inductor well into the HF switching range, suitable for converters switching at 1–2 MHz. ## Package and rework considerations The shielded ferrite construction reduces radiated EMI, which helps when routing near sensitive analog or RF traces. The part is supplied in tape-and-reel for automated pick-and-place.","metaTitle":"Murata LQH3NPN3R3MGRL Drum Core Inductor, 3.3 µH, 940 mA","metaDescription":"Murata LQH3NPN3R3MGRL shielded wirewound inductor, 3.3 µH ±20%, 940 mA, 144 mOhm DCR, 30 MHz SRF, 1212 package.
