22 µH shielded power inductor for DC-DC filtering
The Murata LQH3NPN220MGRL is a 22 µH shielded wirewound inductor in the LQH3 series, built for power rail filtering in space-constrained surface-mount designs. 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.
