330 µH drum core inductor for low-current filtering
The Murata LQH32MN331K23L is a drum core, wirewound inductor in the LQH32 series, delivering 330 µH inductance with a 65 mA current rating and a maximum DC resistance of 13 Ohm. Unshielded construction means the magnetic field is not contained within a ferrite shield — the component relies on board layout and separation from nearby traces to avoid coupling into adjacent circuits.
1210 footprint and rework considerations
The self-resonant frequency is 5 MHz, so the inductance holds up to low-MHz switching regulators but rolls off above that — keep the switching frequency below 5 MHz for the full inductance value.
