The 560 µH value and the 60 mA current ceiling mean it is sized for low-current filtering or energy storage in a DC-DC converter output stage where the load pulls under 50 mA steady-state — the 60 mA rating gives a 20% margin for ripple current at the switching frequency. The self-resonant frequency is 2.7 MHz, which sets the upper bound for the switching frequency of the converter it feeds — above 2.7 MHz the inductor behaves capacitively and the filtering collapses. For a 1 MHz buck converter the 2.7 MHz SRF leaves enough headroom. ## AEC-Q200 — why this matters for the BOM Rated AEC-Q200, the inductor is qualified for automotive-grade stress — temperature cycling, vibration, and humidity bias per the AEC-Q200 passive-component standard. ## Package and footprint — 1812 body, unshielded The unshielded construction means the inductor radiates a magnetic field — keep sensitive analog traces or low-level sensor inputs at least 5 mm away from the body to avoid coupling into the signal path. The Q factor is 40 at 796 kHz, which is a moderate Q for a wirewound ferrite-core inductor at this inductance — the core losses dominate over the winding resistance at the test frequency. For a resonant tank circuit, the 40 Q means the -3 dB bandwidth is about 20 kHz around the 796 kHz centre.","metaTitle":"Murata LQH43NH561J03L Inductor, 560 µH, 60 mA, AEC-Q200","metaDescription":"Murata LQH43NH561J03L drum core wirewound inductor, 560 µH, 60 mA, 13.56 Ohm DCR, AEC-Q200.
