470 nH shielded power inductor for automotive DC-DC converters
The Murata LQH32PHR47NN0L is a drum-core wirewound inductor in the LQH32 series, shielded construction, rated 470 nH ±30% with a 2.55 A continuous current rating and a 3.4 A saturation current floor. Self-resonant frequency is 100 MHz, well above typical 1–4 MHz switching frequencies for automotive buck converters, so the inductor behaves as a pure inductive element in-band without parasitic capacitance effects.
AEC-Q200 qualification and shielded construction for harsh environments
The ferrite core and magnetic shielding contain the flux within the component body, reducing radiated EMI into nearby traces and sensitive analog circuits on the same board — a practical advantage for tightly packed power stages in ECU and ADAS power supplies.
