22 µH wirewound inductor for automotive power filtering
The Murata LQH43NH220J03L is a drum core wirewound inductor in the LQH43 series, offering 22 µH inductance with ±5% tolerance in an 1812 (4532 Metric) surface-mount package. Rated for 300 mA continuous current with a maximum DC resistance of 564 mOhm, this part is sized for low-current power rail filtering or signal conditioning where the DC loss budget allows the DCR drop.
Unshielded ferrite core with self-resonant frequency at 15 MHz
Built on a ferrite core without magnetic shielding, the LQH43NH220J03L has a self-resonant frequency of 15 MHz and a Q factor of 35 measured at 1 MHz — the unshielded construction means adjacent traces or components on the same board layer should be spaced to avoid coupling.
