6.8 µH wirewound in a 1210 footprint
The LQH32CH6R8M53L is a drum-core, wirewound inductor from Murata's LQH32 series, offering 6.8 µH inductance in an unshielded 1210 (3225 metric) surface-mount package. Rated for 540 mA continuous current with a DC resistance of 250 mOhm, it suits power-supply filtering and DC-DC converter output stages where the inductance value and current rating align with the load budget.
Parametric fit for DC-DC and signal filtering
The 6.8 µH inductance is tested at 1 MHz and the self-resonant frequency sits at 32 MHz — well above typical switching frequencies for buck converters in the 500 kHz to 2 MHz range, so the inductor behaves as a pure inductance in-band without parasitic resonance. The 540 mA current rating is the saturation or thermal limit; for a 12 V to 3.3 V buck delivering 400 mA, the peak inductor current stays under this ceiling with margin. Unshielded construction means the magnetic field radiates — adjacent traces carrying sensitive analog signals should be kept at least one package width away to avoid coupling.
