The 710 mΩ DC resistance sets the I²R loss budget — at full rated current the self-heating is roughly 44 mW, which is manageable in most 1210 footprint layouts but should be factored into the thermal design if the inductor sits near temperature-sensitive components. The unshielded construction means the magnetic field extends beyond the component body. In a dense PCB layout, keep sensitive traces or other magnetics at least one component width away to avoid coupling. The 19 MHz self-resonant frequency (SRF) means the inductor behaves inductively up to roughly 19 MHz — above that the parasitic capacitance dominates and the impedance rolls off. For a typical buck converter switching at 500 kHz to 2 MHz, this part provides clean filtering with margin. The ferrite core and wirewound construction give it a low profile that fits under low-clearance components or shielding cans. Tape-and-reel packaging suits automated pick-and-place assembly; the ±10% tolerance is standard for power filtering where the exact inductance value is not critical for loop stability.","metaTitle":"Murata LQH32CH220K23L 22 µH Wirewound Inductor, 250 mA","metaDescription":"Murata LQH32CH220K23L drum core wirewound inductor, 22 µH ±10%, 250 mA, 710 mΩ DCR, 19 MHz SRF.
