Rated for 250 mA DC current with a maximum DC resistance of 840 mOhm, it is designed for power supply filtering and DC-DC converter applications where the unshielded construction is acceptable. ## Fit and performance boundaries The 33 µH inductance is measured at 1 MHz; the self-resonant frequency is 12 MHz, so the effective inductive region extends to roughly that frequency before parasitic capacitance dominates. The Q factor of 35 at 1 MHz gives a reasonable efficiency for resonant circuits at that frequency, but for power filtering the DCR of 840 mOhm is the main loss contributor — at 250 mA the I²R loss is about 52 mW, which combined with core loss at switching frequencies should be checked against the ambient temperature derating.","metaTitle":"Murata LQH43NH330J03L 33 µH Unshielded Inductor, 250 mA","metaDescription":"Murata LQH43NH330J03L drum core wirewound inductor, 33 µH ±5%, 250 mA, 840 mOhm DCR, AEC-Q200, 1812 SMD.
