6.8 µH shielded wirewound for DC-DC filtering
The Murata LQH2HPN6R8MG0L is a 6.8 µH shielded wirewound inductor in the LQH2 series, built for surface-mount DC-DC converter output and input filtering where the 590 mA continuous current rating covers the rail budget.
Sourcing an obsolete LQH2 inductor
For an existing board in production, the part is sourced per RFQ through distribution that holds end-of-life inventory — lot traceability and date codes confirmed at quote time.
Current rating and saturation headroom
The 590 mA continuous current rating is the thermal limit; the saturation current (Isat) is 800 mA, so the core holds inductance up to roughly 35% above the rated current before the inductance roll-off begins. Self-resonant frequency at 10 MHz means the inductor behaves as an inductor well below that — for a 1-2 MHz switching regulator, the impedance is still inductive and the SRF is not a concern. Inductance is tested at 1 MHz, which is the standard test frequency for this value range and confirms the core material's permeability at the switching frequencies these parts typically see.
