It is rated for 250 mA continuous current with a maximum DC resistance of 923 mOhm, making it a fit for low-power DC-DC converter output filters, bias-T networks, and signal-line decoupling where the self-resonant frequency of 19 MHz sets the usable band ceiling. ## Parametric fit for the BOM line Inductance is 22 µH at 1 MHz test frequency, ±10% tolerance. DC resistance at 923 mOhm max produces a 230 mW I²R loss at full rated current — acceptable for a 1210 footprint but worth derating if the ambient is above 70 °C. The ferrite core and unshielded construction mean the flux couples into nearby traces; keep sensitive analog routing 2–3 mm clear. Self-resonant frequency at 19 MHz limits effective filtering to below roughly 5 MHz — above that the parasitic capacitance dominates and the inductor behaves capacitively.","metaTitle":"Murata LQH32CN220K53L 22µH Inductor, 250mA, 923mOhm","metaDescription":"Murata LQH32CN220K53L 22µH unshielded wirewound inductor, 250mA, 923mOhm DCR, 19MHz SRF, -40~85°C.
