Rated for 70 mA continuous current with a maximum DC resistance of 14.5 Ohm, this unshielded inductor suits low-to-moderate current applications where the inductance value and Q factor at 796 kHz are the primary selection criteria. ## What the key ratings mean for your circuit The 560 µH inductance at 1 kHz test frequency, combined with a self-resonant frequency of 2.7 MHz, means this inductor provides effective filtering up to the low-MHz range before parasitic capacitance dominates the impedance. A Q factor of 40 at 796 kHz indicates moderate efficiency at that frequency — the ratio of reactance to resistance means some energy is lost as heat in the winding, which is typical for a wirewound part at this inductance value. The 14.5 Ohm DCR at 70 mA produces an I²R loss of roughly 71 mW — this self-heating should be factored into the thermal budget, especially in dense PCB layouts where the 1812 package has limited copper area to dissipate heat.","metaTitle":"Murata LQH43NN561J03L 560 µH Wirewound Inductor, 70 mA","metaDescription":"Murata LQH43NN561J03L drum core wirewound inductor, 560 µH, 70 mA, 14.5 Ohm DCR, 1812 SMD.
