1 µH, 800 mA — DC bias headroom for power rail filtering
The LQH32DN1R0M23L is a 1 µH unshielded wirewound inductor from Murata's LQH32 series, rated 800 mA with a maximum DC resistance of 117 mOhm. The DCR and current rating together define the DC bias headroom: at 800 mA the resistive loss is roughly 75 mW, which is well within the part's self-heating budget for a 105°C ambient ceiling. The self-resonant frequency is 96 MHz, meaning the inductor behaves inductively up to that point; above it the parasitic capacitance dominates and the impedance drops. For switching regulators or filter networks operating below 10 MHz, the SRF provides ample margin.
Package and footprint — 1210 (3225 metric)
Surface-mount in a nonstandard 1210 case (3.20 x 2.50 mm footprint, 2.20 mm seated height). The ferrite core is unshielded, so adjacent traces or components in a dense layout may pick up stray flux — keep sensitive signal lines at least one part width away. Not AEC-Q200 qualified, so not recommended for under-hood or transmission-mounted automotive applications without derating analysis.
