It is rated for 1.6 A continuous current, with a saturation current floor of 1.55 A — the two figures are nearly equal, so the usable current is limited by saturation onset, not thermal rise. The 91.2 mOhm max DCR sets the I²R conduction loss — at 1.6 A the self-heating is about 233 mW, which the 1210 body dissipates into the PCB copper without exceeding the 125 °C rated ambient. ## Current rating and saturation margin The 1.6 A current rating and 1.55 A saturation current (Isat) are within 3% of each other — this means the inductance starts rolling off just above the rated current. For a buck converter output filter, the peak inductor current must stay below 1.55 A to maintain ripple attenuation; a design margin of 20% below Isat is typical. The self-resonant frequency of 70 MHz places the usable inductance band well above the switching frequencies of most DC-DC converters (typically 500 kHz to 3 MHz), so the inductor behaves as a pure inductive element in that range. ## Shielding and EMI containment The shielded construction contains the magnetic flux within the ferrite core, reducing radiated EMI into adjacent traces and components. In a dense mixed-signal layout — a sensor module or a radio front-end — this avoids coupling into the analog or RF section without requiring a separate shield can. The 1210 (3225 metric) footprint and 1.70 mm seated height fit standard pick-and-place assembly. The nonstandard package designation means the pad layout matches the 1210 chip outline — confirm the land pattern against the manufacturer's recommended footprint before committing the PCB.","metaTitle":"Murata LQH32PB2R2NN0L 2.2 µH Shielded Inductor, 1.6 A","metaDescription":"Murata LQH32PB2R2NN0L 2.2 µH shielded wirewound inductor, 1.6 A rated, 91.2 mOhm DCR, -40 to +125°C.
