The self-resonant frequency of 33 MHz defines the upper bound for effective filtering — above this the inductor behaves capacitively. The Q factor of 30 at 1 MHz gives a reasonable AC loss figure for a ferrite-core part at that frequency, useful for resonant circuits or band-pass filtering in the low-MHz range. ## 1812 footprint and unshielded construction The unshielded construction means magnetic flux couples to nearby traces and components — maintain clearance from sensitive signal paths or use a shielded alternative if crosstalk is a concern in dense layouts. The ferrite core material provides stable inductance over temperature and current, though the unshielded design saturates gradually rather than sharply. Tape-and-reel packaging supports automated pick-and-place for volume assembly.","metaTitle":"Murata LQH43NN5R6K03L 5.6 µH Wirewound Inductor, 500 mA","metaDescription":"Murata LQH43NN5R6K03L drum core wirewound inductor, 5.6 µH ±10%, 500 mA, 470 mOhm DCR, 1812 SMD, active production.
