Rated at 450 mA continuous current with a saturation current floor of 500 mA, this part handles the ripple current of a moderate-load buck or boost stage without saturating the ferrite core. ## What the ratings mean for the BOM The 972 mOhm max DCR sets the copper loss: at 450 mA, I²R dissipation is roughly 0.2 W, which the 1210 body must sink into the board copper — a factor when the inductor sits near a hot regulator or in a confined ambient. Self-resonant frequency is 20 MHz, so the inductor behaves inductively well below that — usable for switching converters switching at 1–2 MHz or lower, where the SRF is at least a decade above the fundamental. Shielded construction with ferrite core contains the magnetic field, reducing EMI coupling to adjacent traces and components — a practical advantage when routing a noisy power rail near a sensitive analog section on the same board.","metaTitle":"LQH32PN220MN0L Murata 22 µH Shielded Inductor, 450 mA","metaDescription":"Murata LQH32PN220MN0L 22 µH ±20% shielded wirewound inductor, 450 mA, 972 mOhm DCR, 1210 package.
