68 µH drum core wirewound for signal filtering and DC-DC output smoothing
The Murata LQH2MCN680K02L is a drum core wirewound inductor in the LQH2 series, delivering 68 µH inductance with ±10% tolerance in an 0806 (2016 Metric) surface-mount package. Rated for 100 mA continuous current with a maximum DC resistance of 8.58 Ohm, this part is sized for low-current filtering stages where the inductance value matters more than the current handling.
What the 100 mA current rating and 8.58 Ohm DCR mean for your circuit
At 100 mA the inductor's I²R loss is 86 mW — the 8.58 Ohm DCR is the dominant source of heat in this small 0806 body, so the actual usable current in a dense board may need derating below the absolute maximum. The unshielded construction means magnetic flux radiates from the drum core — keep sensitive analog traces or RF loops at least a few millimeters away from the part's footprint to avoid coupling. Inductance is tested at 1 MHz, which is the standard reference frequency for this value range; the part's impedance rolls off above 14 MHz as the self-resonant frequency is approached.
