Rated at 670 mA continuous with a saturation current floor of 570 mA, it handles the ripple current of a moderate-load buck converter without entering hard saturation. ## DC resistance and conduction loss The maximum DC resistance is 336 mOhm — at 670 mA the I²R loss is 151 mW, which must be dissipated into the 1212 (3030 Metric) footprint. The ferrite core material keeps core losses low at typical switching frequencies below the 20 MHz self-resonant point. ## Temperature range and saturation margin Operating from -40°C to 105°C, the inductor suits industrial and automotive-adjacent environments where the ambient inside an enclosure can reach 85°C. The saturation current of 570 mA is 85% of the rated current — a 15% margin means the inductance holds within tolerance under peak transient loads, but the margin narrows at high temperature as the core approaches saturation earlier.","metaTitle":"Murata LQH3NPN100MGRL 10µH Shielded Inductor, 670mA","metaDescription":"Murata LQH3NPN100MGRL drum core wirewound inductor, 10µH ±20%, shielded, 670mA rated, 336mOhm DCR, 1212 package.
