It carries a continuous current rating of 95 mA with a maximum DC resistance of 8.2 Ohm — the DCR sets the I²R loss and voltage drop in the path, so the 95 mA figure is the thermal limit at which the temperature rise stays within the ferrite's operating envelope. ## 1812 footprint and temperature grade for industrial PCB integration The Q factor is 40 at 796 kHz, and the self-resonant frequency is 3.6 MHz. Above the SRF the inductor behaves capacitively, so the useful filtering range stops well below 3.6 MHz — for a 330 µH value, the SRF is high enough to keep the component inductive across the audio band and into the low RF range, suiting it for EMI line filtering or decoupling a low-current bias rail.","metaTitle":"Murata LQH43NN331J03L 330 µH Inductor, 95 mA, 1812","metaDescription":"Murata LQH43NN331J03L drum core wirewound inductor, 330 µH ±5%, 95 mA rated current, 8.2 Ohm DCR, 1812 SMD package.
