The ferrite core and drum-core construction keep the self-resonant frequency at 250 MHz, making it suited for RF decoupling and impedance matching in the VHF band. This part is in Last Buy status — the manufacturer has announced end-of-life, so remaining stock is finite. ## Parametric fit for RF and decoupling With a Q factor of 20 at 25 MHz, the inductor maintains reasonable selectivity in tuned circuits at that frequency. The 1206 (3216 Metric) footprint is a standard size for RF inductors, and the unshielded construction means the magnetic field extends beyond the package — adjacent traces or components should be spaced to avoid coupling, especially in sensitive RF front-ends. ## Sourcing and compliance The LQH31MNR15K03L is supplied through independent distribution channels; pricing and lead time are confirmed at RFQ against the BOM quantity.","metaTitle":"Murata LQH31MNR15K03L 150 nH Unshielded Inductor, 250 mA","metaDescription":"Murata LQH31MNR15K03L drum core wirewound inductor, 150 nH, 250 mA, 546 mOhm DCR, 1206 package.
