Active AEC-Q200 qualified 39 µH shielded inductor
The Murata LQH2HNH390J03L is an active-production drum-core wirewound inductor in the LQH2 series, qualified to AEC-Q200 for automotive-grade reliability. Rated 39 µH ±5% with a DC resistance of 4 Ohm and a saturation current of 80 mA — the DCR is the dominant loss term at this inductance value, so the 80 mA limit reflects the I²R thermal rise, not core saturation. Shielded ferrite core construction keeps flux leakage low, which matters when the inductor sits next to sensitive analog or RF traces on the same PCB.
Self-resonant frequency and temperature range
Self-resonant frequency is 15 MHz — above that the inductor behaves capacitively, so filter designs must keep the switching or signal frequency well below this ceiling.
Available in tape-and-reel or cut-tape quantities; the AEC-Q200 rating means the part has passed the full automotive stress-test sequence (thermal shock, humidity, vibration).
