Shielded 100 µH inductor for DC-DC and power-line filtering
The LQH32PB101MN0L is a shielded drum-core wirewound inductor from Murata's LQH32 series, rated at 100 µH with ±20% tolerance and a DC resistance of 3.24 Ohm max. The 250 mA current rating and 180 mA saturation current define the usable load range — stay below the saturation point to keep inductance stable. The self-resonant frequency of 8 MHz means this inductor behaves as an inductor well below that frequency; above it, parasitic capacitance dominates. For typical DC-DC converters switching at a few hundred kHz to 2 MHz, the 100 µH value provides ripple attenuation without hitting the SRF ceiling. The nonstandard package designation means the pad layout follows the 1210 chip footprint — confirm the land pattern against the datasheet drawing before layout.
