1 µH shielded power inductor for DC-DC rail filtering
The Murata LQH32PN1R0NNCL is a 1 µH shielded wirewound inductor in the LQH32 series, rated for 2.5 A continuous with a saturation current of 3 A.
Shielding and self-resonant frequency — what they mean for your rail
Shielded construction (ferrite core) contains the magnetic field, so this inductor can sit next to sensitive analog traces or RF sections without coupling noise into adjacent circuits. The self-resonant frequency of 100 MHz sets the upper bound for useful filtering — above that frequency the part behaves capacitive, so it is best suited for switching converters switching below 10 MHz.
Tape-and-reel packaging supports automated pick-and-place; the ±30% tolerance on 1 µH is typical for power-grade ferrite inductors where the inductance value is less critical than saturation margin.
