4.7 µH, 650 mA — DC-DC filtering workhorse
The Murata LQH32CH4R7M33L is a 4.7 µH ±20% wirewound drum core inductor in the 1210 (3225 Metric) footprint, rated for 650 mA continuous current with a DCR of 150 mOhm. That DCR figure is the one that governs the copper loss at load — at 650 mA the I²R loss is about 63 mW, well within the 85 °C ambient ceiling for a part this size. Unshielded construction means the external field couples into nearby traces — keep sensitive analog or RF routing at least one part width away. The self-resonant frequency of 43 MHz tells you this inductor behaves as an inductor up to roughly 40 MHz; above that the parasitic capacitance dominates and the impedance rolls off.
