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. ## Active lifecycle and sourcing posture Marked as Active in production.","metaTitle":"Murata LQH32CH4R7M33L Drum Core Inductor, 4.7 µH, 650 mA","metaDescription":"Murata LQH32CH4R7M33L wirewound drum core inductor, 4.7 µH ±20%, 650 mA, 150 mOhm DCR, 1210 package.
