The self-resonant frequency of 130 MHz places the usable inductance band well above typical switching-regulator frequencies (100 kHz–2 MHz), so the inductor behaves as a pure inductive element in the loop without capacitive crossover. The unshielded construction means the external field couples into nearby traces — keep a ground plane under the footprint or allow 2–3 mm keep-out to adjacent sensitive nodes. ## 1812 footprint, surface-mount assembly The ferrite core and wirewound construction are reflow-solder compatible; the part handles standard lead-free profiles up to 260 °C peak.","metaTitle":"Murata LQH43CNR82M33L Drum Core Inductor, 820 nH, 2.8 A","metaDescription":"Murata LQH43CNR82M33L wirewound inductor, 820 nH ±20%, 2.8 A, 35 mOhm DCR, 1812 SMD.
