Rated for 450 mA continuous current with a saturation current floor of 390 mA, it suits low-to-moderate current DC-DC converter output stages and input filter chokes. ## Shielded construction and package fit Magnetic shielding contains the flux within the 3.00 mm x 3.00 mm footprint, reducing radiated coupling into adjacent traces — a useful property when the inductor sits near a sensitive ADC or RF section on the same layer. The 1212 (3030 Metric) case with a 1.00 mm seated height fits under low-profile components or on the backside of a densely populated board. Self-resonant frequency is 10 MHz, so the inductor behaves inductively well below that point — suitable for switching regulators switching in the 500 kHz to 2 MHz range where the SRF margin is comfortable.","metaTitle":"Murata LQH3NPN220MGRL Shielded Power Inductor, 22 µH","metaDescription":"Murata LQH3NPN220MGRL shielded wirewound inductor, 22 µH ±20%, 450 mA, 636 mOhm DCR.
