Rated for 700 mA continuous current, it suits power-supply decoupling and resonant circuits in the VHF band. ## Q and self-resonance — what they mean for filter design A Q factor of 60 at 100 MHz indicates a tight, low-loss resonance — useful for narrowband impedance matching or LC tank circuits where the inductor's series resistance dominates the bandwidth. The self-resonant frequency of 500 MHz marks the upper bound for inductive behaviour; above this frequency the part behaves capacitively. For a 145 nH inductor, that leaves a wide useful band up to several hundred MHz. The ferrite core construction handles the 700 mA without saturating, and the wirewound geometry delivers the Q needed for RF-stage decoupling.","metaTitle":"Murata LQH31HNR14J03L Inductor, 145 nH, 700 mA, 1206","metaDescription":"Murata LQH31HNR14J03L drum core wirewound inductor, 145 nH ±5%, 700 mA, 61 mOhm DCR, 1206 package.
