470 nH shielded power inductor for automotive DC-DC
The Murata LQH2MPZR47NGRL is a drum-core wirewound inductor in the LQH2 series, delivering 470 nH ±30% in a shielded 0806 (2016 Metric) package. Rated at 1.06 A continuous with a saturation current floor of 1.95 A, it handles the ripple current in a 12 V-to-3.3 V buck converter without saturating the ferrite core.
AEC-Q200 qualification and temperature profile
Rated AEC-Q200, this inductor is qualified for automotive stress tests including thermal shock, moisture resistance, and mechanical shock per the AEC-Q200 passive component standard.
DC resistance and self-resonant frequency
216 mOhm max DCR sets the I²R conduction loss — at 1.06 A the copper loss is 243 mW, which the 0806 body dissipates without exceeding the 105°C ambient limit when mounted on a standard PCB with 1 oz copper. Self-resonant frequency at 120 MHz means the inductor behaves inductively well into the 10-30 MHz switching range typical of automotive DC-DC converters.
