The 1008 (2520 metric) footprint and 1.00 mm seated height fit tight PCB stacks where the self-resonant frequency of 200 MHz keeps the inductor above the switching noise band of a 2 MHz DC-DC converter. AEC-Q200 qualification means this inductor passed the automotive-grade stress tests: thermal shock, moisture resistance, and mechanical shock per the passive-component qualification standard. ## DC resistance and current rating: the thermal budget check At 520 mA the 124 mOhm DCR produces a self-heating I²R loss of 33.5 mW. In a 125°C ambient the temperature rise stays within the ferrite core's Curie limit, but the board-level copper pad area under the 1008 package sets the actual thermal resistance — a solid ground-plane pour on the inner layer pulls heat out of the component faster than a narrow trace. The ±10% tolerance on 680 nH means the actual inductance at the DC bias point can shift by up to 68 nH. For a buck converter's output filter, this shifts the corner frequency; the control-loop compensation should be designed for the worst-case inductance, not the nominal value.","metaTitle":"Murata LQH2HNHR68K03L Inductor, 680 nH, 520 mA, AEC-Q200","metaDescription":"Murata LQH2HNHR68K03L shielded wirewound inductor, 680 nH ±10%, 520 mA, 124 mOhm DCR, AEC-Q200 qualified.
