Parametric fit for automotive and industrial DC-DC
The LQH2HNH3R3J03L is a 3.3 µH shielded wirewound inductor in the Murata LQH2 series, rated for 260 mA continuous current with a maximum DC resistance of 400 mΩ. The ±5% tolerance holds the inductance tight enough for a buck converter's output filter without needing a wider-margin derating. The self-resonant frequency of 80 MHz is well above the switching frequency of most DC-DC converters (typically 500 kHz to 2 MHz), so the inductor behaves as a pure inductive element in the passband without parasitic capacitive coupling stealing efficiency.
The shielded ferrite core contains the magnetic field, so adjacent traces on a 0.8 mm board pitch see minimal coupling — no keep-out zone beyond the standard 0.5 mm pad extension. Available on tape-and-reel (cut tape also offered) for pick-and-place assembly. The 1 MHz test frequency is the standard condition for inductance measurement; the part's performance at the converter's operating frequency will be within the datasheet's tolerance band.
