The Murata LQH32DN470K23L is a 47 µH unshielded wirewound inductor in the LQH32 series, built on a ferrite core.
The self-resonant frequency is 15 MHz — above that point the inductor behaves capacitively, so it is suited for switching converters and filter stages operating well below 15 MHz, such as a 1 MHz DC-DC output filter.
Tolerance is ±10%, and the inductance is measured at 1 MHz.
