It is rated for 180 mA continuous current and saturates at 160 mA, with a maximum DC resistance of 5.88 Ω. The self-resonant frequency sits at 3 MHz, which sets the upper limit for effective filtering in a buck or boost converter — above that, the inductive impedance drops and the part behaves capacitively. ## Current derating and saturation margin The rated current (180 mA) and saturation current (160 mA) are close — only 20 mA apart — so the design headroom is tight. In a power rail that sees transient peaks above 160 mA, the inductance will drop sharply, and the output ripple will increase. ## Shielding and board integration The shielded construction reduces magnetic coupling to adjacent traces and components — useful in a compact 3.00 mm × 3.00 mm footprint where the inductor sits close to a sensitive ADC or RF front-end. The 1.00 mm seated height keeps it low-profile for tight enclosures. The 1212 (3030 Metric) package is a standard footprint, and the part is offered in both Tape & Reel and Cut Tape options for prototyping or volume assembly.","metaTitle":"Murata LQH3NPN151MGRL 150 µH Shielded Inductor, 180 mA","metaDescription":"Murata LQH3NPN151MGRL shielded wirewound inductor, 150 µH ±20%, 180 mA rated, 5.88 Ω DCR, 3 MHz SRF, -40 to +85 °C.
