Shielded 10 µH inductor for DC-DC input/output filtering
The Murata LQH32PB100MN0L is a shielded drum-core wirewound inductor in the LQH32 series, offering 10 µH ±20% inductance with a 700 mA rated current and a saturation current of 750 mA.
Rated current and DCR — what they mean for your power rail
The 700 mA current rating is the continuous DC current at which the temperature rise stays within the design limit; the 750 mA saturation current (Isat) is the point where inductance drops by roughly 30% — so the inductor starts to lose its filtering ability above 700 mA, and the margin between rated and saturation is tight at 50 mA. Maximum DC resistance is 456 mOhm — at 700 mA the I²R conduction loss is about 223 mW, which heats the part and must be accounted for in the thermal budget, especially in a dense board with limited airflow. Shielded ferrite core construction contains the magnetic field, reducing radiated EMI that could couple into nearby signal traces or sensitive analog circuits on the same board.
