What the 68 µH rating means for your rail
The LQH32PN680MN0L is a shielded wirewound inductor in Murata's LQH32 series, built on a ferrite core with a drum-core construction. The 68 µH inductance is tested at 1 MHz and holds within ±20% across the rated current range. Rated for 275 mA continuous current with a saturation current floor of 280 mA — the inductor stays within its linear region right up to the rated load, so a DC-DC converter drawing 250 mA won't see a collapse in inductance at peak demand.
DC resistance and self-resonant frequency — the trade-offs
The self-resonant frequency sits at 11 MHz, so the inductor behaves as an inductor up to that point; above 11 MHz parasitic capacitance dominates and the impedance rolls off. The ferrite core and shielded construction keep the magnetic field contained — useful when the inductor sits close to sensitive analog traces or RF stages on the same board.
The footprint matches the standard 1210 land pattern; the 2.20 mm height is low enough for most card-edge clearance envelopes. Supplied on tape and reel — cut-tape quantities are available for prototyping, while full reels suit production runs. The part is RoHS-compliant by Murata's standard material declaration.
