The 530 mA current rating is the DC bias limit where the inductance starts to roll off — for a 3.3 µH part in a buck converter drawing 400 mA, the margin is comfortable, but pushing past 530 mA means the effective inductance drops below the value the control loop was designed around. ## Unshielded construction and 50 MHz SRF — where it fits and where it doesn't Unshielded construction means the magnetic field radiates into the surrounding board area — keep sensitive analog traces or other magnetics at least one part-width away to avoid coupling. The self-resonant frequency of 50 MHz sets the practical upper limit for the inductor in a filter or DC-DC application; above that frequency the component behaves capacitively and the impedance drops. ## Active production — sourcing posture for this LQH32 variant Available in Tape & Reel (TR) or Cut Tape (CT) packaging; the base product number LQH32DN covers the full inductance range in this drum-core family.","metaTitle":"Murata LQH32DN3R3M23L Inductor, 3.3 µH, 530 mA","metaDescription":"Murata LQH32DN3R3M23L drum core wirewound inductor, 3.3 µH, 530 mA, 260 mOhm DCR, 1210 package.
