2.2 µH shielded wirewound for DC-DC filtering
The Murata LQH3NPN2R2MGRL is a 2.2 µH shielded drum-core wirewound inductor in a 1212 (3030 Metric) surface-mount package. It is part of the LQH3 series and is rated for 1.03 A continuous current with a saturation current of 1.18 A.
Last Buy — sourcing window is closing
Murata has flagged the LQH3NPN2R2MGRL as Last Buy. This means the manufacturer has stopped accepting new orders, and the remaining inventory in the distribution channel is the final available stock. For a BOM line that depends on this exact inductance, current rating, and 1212 footprint, the procurement decision is time-sensitive.
Ferrite core, shielded construction, 50 MHz SRF
The ferrite core material and shielded construction keep the magnetic field contained — adjacent traces on a dense PCB see less eddy-current coupling than an unshielded drum core would allow. The self-resonant frequency of 50 MHz sits well above the switching fundamental of a 2–3 MHz buck converter, so the inductor behaves as a pure inductance in the passband. The inductance is tested at 1 MHz, which is the standard test frequency for this value range.
