1 µH shielded power inductor for DC-DC rail filtering
The Murata LQH32PN1R0NN0L is a 1 µH shielded wirewound inductor from the LQH32 series, built on a ferrite drum core. It carries a continuous current rating of 2.05 A and a saturation current of 2.3 A, making it a fit for point-of-load filtering in buck converters where the inductor sees the full switch current without saturating.
Shielding and self-resonant behaviour
The self-resonant frequency is 100 MHz — well above the 1 MHz test frequency and typical switching frequencies for 1 µH rails in 2-3 MHz converters, so the inductive impedance dominates across the operating band. Tolerance is ±30% at 1 MHz, which is standard for power-grade ferrite-core inductors; the inductance drop under DC bias is captured by the 2.3 A saturation current spec.
Surface-mount termination with Tape & Reel packaging supports automated pick-and-place; the part is RoHS-compliant per Murata's standard lead-free finish.
