It is rated for 650 mA continuous current with a saturation current (Isat) matching the rated current at 650 mA, meaning the inductance holds its value up to the full current rating before rolling off. ## Self-resonant frequency and switching noise The self-resonant frequency (SRF) is 40 MHz. Above this frequency the inductor behaves capacitively, so it is effective as a power-supply filter or DC-DC converter output choke for switching frequencies up to a few MHz — well within the SRF margin for typical buck converters operating at 1-2 MHz. Shielding contains the magnetic field within the component body, which reduces radiated EMI coupling to nearby traces or sensitive analog circuits on the same board layer. ## Sourcing and lifecycle posture For a single-source BOM line, qualifying an alternate from the same LQH2 series with matching inductance and current rating at RFQ time is a hedge worth considering.","metaTitle":"Murata LQH2HPN4R7MDRL 4.7 µH Shielded Inductor, 650 mA","metaDescription":"Murata LQH2HPN4R7MDRL 4.7 µH shielded wirewound inductor, 650 mA, 672 mOhm DCR, 1008 package.
