Its 70 mA current rating and 14.5 Ohm max DCR define the load and loss budget for DC-DC output filters, bias line chokes, and low-frequency signal conditioning where the self-resonant frequency of 2.7 MHz is not exceeded. ## What the key ratings mean for your BOM line At 560 µH ±5%, this part suits applications needing a moderate inductance value with tight tolerance, such as LC filters or ripple suppression in low-current rails. The 70 mA continuous current rating is the hard ceiling — exceeding it saturates the ferrite core and collapses inductance, so derate for ambient temperature and ripple current when sizing for a 50 mA load. The 14.5 Ohm max DCR at 70 mA produces an I²R loss of roughly 71 mW, which is manageable in free air but should be factored into the thermal budget if the inductor is in a densely populated board section. A Q factor of 40 at 796 kHz indicates reasonable AC loss at typical switching frequencies for this inductance class. The 2.7 MHz self-resonant frequency means the part behaves inductively below that point — above it, parasitic capacitance dominates and the impedance drops. ## Active production — sourcing posture It is available through both authorized distribution and independent channels.","metaTitle":"Murata LQH43MN561J03L 560 µH Inductor, 70 mA, 1812","metaDescription":"Murata LQH43MN561J03L unshielded wirewound inductor, 560 µH ±5%, 70 mA, 14.5 Ohm DCR, 1812 SMD.
