100 µH, 320 mA — shielded drum-core inductor for power and filtering
The Murata LQH43PN101M26L is a shielded drum-core wirewound inductor in the LQH43 series, rated 100 µH ±20% with a DC current rating of 320 mA and a matching saturation current of 320 mA. The ferrite core and full magnetic shield keep flux leakage low, making this a good fit for DC-DC converter input/output filters or power-supply rail smoothing where adjacent traces need EMI containment.
Self-resonant frequency and usable band
Self-resonant frequency is 4 MHz — above this point the inductor's impedance becomes capacitive, so the part is best used in switching converters or filter stages operating below 2–3 MHz where the inductive impedance dominates. Inductance is tested at 1 MHz, confirming the part is characterised in the lower-frequency power range rather than RF decoupling.
Active lifecycle — no near-term obsolescence risk
The base product number LQH43PN covers multiple inductance values in the same footprint, making it easy to adjust the BOM without a board spin if the circuit needs a different µH.
