Rated for 800 mA continuous current with a maximum DC resistance of 130 mOhm, the part suits low- to moderate-current filtering and DC-DC converter output stages where the 3.3 µH value provides the needed ripple attenuation. ## Self-resonant ceiling and temperature grade The self-resonant frequency of 47 MHz defines the upper limit of the inductive region — above this frequency the impedance becomes capacitive, so the inductor is usable for switching regulators switching below roughly 4.7 MHz (one-tenth of SRF as a rule of thumb) and for EMI filtering up to the VHF band.","metaTitle":"Murata LQH43CN3R3M03L 3.3 µH Unshielded Inductor, 800 mA","metaDescription":"Murata LQH43CN3R3M03L drum core wirewound inductor, 3.3 µH ±20%, 800 mA, 130 mOhm DCR, 1812 SMD.
