Rated at 350 mA continuous with a DCR of 600 mOhm max, the copper loss at full current is about 74 mW — negligible in most designs, but the DCR matters more if you're running close to the current limit in a tight thermal budget. The ferrite core and shield keep the magnetic field contained, so you can place this inductor next to sensitive analog traces or a nearby IC without coupling noise into the signal path. ## Saturation headroom and self-resonant ceiling Saturation current (Isat) is 520 mA, meaning the inductance holds its value up to about 50% above the rated DC current — a solid margin for transient spikes on a 350 mA rail. Self-resonant frequency is 20 MHz; above that the component stops behaving as an inductor and starts looking capacitive. For a 1–2 MHz switching regulator this is well clear, but if you're using it in a higher-frequency filter or a resonant tank, check that the operating band stays below 20 MHz.","metaTitle":"Murata LQH3NPN220MJRL 22µH Shielded Wirewound Inductor","metaDescription":"Murata LQH3NPN220MJRL 22µH shielded wirewound inductor, 350mA, 600mOhm DCR, 1212 package.
