Rated for 650 mA continuous current with a maximum DC resistance of 130 mOhm — the DCR sets the I²R heating floor, so at full rated current the self-heating is roughly 55 mW, well within the 105°C operating ceiling. The self-resonant frequency of 43 MHz means this inductor behaves as an inductor up to that point; above 43 MHz parasitic capacitance dominates and the impedance rolls off, so it is suited for DC-DC converter output filtering and power rail smoothing where the switching fundamental stays well below 43 MHz. ## 1210 SMD footprint and board integration Unshielded construction means the magnetic field radiates from the core — adjacent traces carrying sensitive analog signals or high-speed digital lines should be kept at least one package width away to avoid coupling.","metaTitle":"Murata LQH32DN4R7M53L Drum Core Inductor, 4.7 µH, 650 mA","metaDescription":"Murata LQH32DN4R7M53L wirewound drum core inductor, 4.7 µH ±20%, 650 mA, 130 mOhm DCR, 1210 SMD.
