The 140 mA continuous current rating and 2.83 Ohm max DCR define the conduction loss budget in a power rail or bias-T application — the DC resistance alone drops 0.4 V at full rated current, so the available voltage at the load is that much lower than the rail feeding the inductor. Shielding is built in, which keeps the magnetic field contained within the component body — useful when the inductor sits near sensitive analog circuitry or a noisy switching node on the same board layer. ## Current handling and saturation margin Rated current is 140 mA, but the saturation current (Isat) is 280 mA — double the continuous rating. This means the inductance holds stable up to 280 mA before dropping off, giving headroom for transient peaks without the inductor saturating and losing its filtering action. The self-resonant frequency is 3 MHz. Above that frequency the inductor behaves capacitively, so the useful filtering band stops well before 3 MHz. For a buck converter switching at 500 kHz to 1 MHz, this part still provides inductive impedance; for a 2 MHz switcher, the margin is thin. The ferrite core material maintains its magnetic properties across this range, though DCR rises with temperature — expect a 20–30% increase in copper loss at 125°C compared to 25°C. Tape-and-reel packaging supports automated pick-and-place for volume assembly.","metaTitle":"Murata LQH43PB151M26L 150 µH Shielded Power Inductor, 140 mA","metaDescription":"Murata LQH43PB151M26L drum core wirewound inductor, 150 µH ±20%, shielded, 140 mA rated current, 1812 package.
