1.8 µH wirewound for automotive and industrial DC-DC
The Murata LQH32NH1R8J23L is a drum core, wirewound inductor in the LQH32 series, delivering 1.8 µH inductance with a ±5% tolerance and a rated current of 635 mA. Its 108 mOhm max DC resistance keeps I²R losses manageable in power rail filtering and DC-DC converter output stages, where every milliohm matters for efficiency.
Unshielded drum core — watch the layout
The self-resonant frequency sits at 80 MHz, so the inductor behaves as an inductor well below that — above 80 MHz the impedance turns capacitive, which matters if you're filtering a 10 MHz switcher with a fast edge rate.
