AEC-Q200 qualified for under-hood and chassis-mount ECU filtering
The Murata LQH32NH150J23L is a drum core wirewound inductor from the LQH32 series, rated at 15 µH with ±5% tolerance and a 270 mA current rating.
DC resistance and self-resonant frequency set the usable bandwidth
The 600 mOhm maximum DCR at 270 mA produces a self-heating I²R loss of roughly 44 mW — negligible in a 1210 footprint but worth checking against the board's local thermal budget if the inductor sits near a hot regulator or in a high-density layout. The self-resonant frequency of 25 MHz defines the upper limit for effective filtering; above that the impedance becomes capacitive, so this part suits DC-DC converter output ripple suppression and power-line noise filtering up to the low-MHz range. The Q factor of 35 at 1 MHz indicates moderate energy storage efficiency at the test frequency — adequate for general-purpose filtering and decoupling in automotive power rails, though not optimised for high-Q tank circuits or RF front-ends where a higher Q at the operating frequency would be specified.
