1 µH shielded power inductor for DC-DC rail filtering
The Murata LQH32PB1R0NNCL is a 1 µH shielded drum-core wirewound inductor in the LQH32 series, rated for 1.38 A continuous with a DCR of 43.2 mΩ max. The ferrite core and shield contain the magnetic field, so it keeps EMI off adjacent traces in a tight power-stage layout — useful when the inductor sits near a sensitive ADC or RF front-end.
Saturation headroom and self-resonant ceiling
Saturation current (Isat) is 3 A, more than double the 1.38 A rated current — the inductance holds flat across the normal load range, and you get margin for transient spikes without the core dropping out. Self-resonant frequency is 100 MHz, well above the switching frequency of most buck converters (typically 500 kHz to 2 MHz), so the inductor behaves as a pure inductor in-band.
Board-fit and temperature grade
Operating range is -40°C to 105°C, covering industrial and automotive cabin environments; the ferrite core material holds permeability across that band without a steep drop-off at the hot end.
