Product details

47 µH at 100 mA — what the ratings mean for the circuit

The LQH32MN470J23L: 47 µH ±5% with a self-resonant frequency of 11 MHz means this inductor is usable as a power-supply output choke or a bias-T inductor in DC-DC converters switching below ~2 MHz — well below the SRF, where the impedance stays inductive.

Unshielded drum core — layout and coupling considerations

As an unshielded drum-core design, the LQH32MN470J23L radiates a fringe field that can couple into nearby traces or adjacent inductors. In a dense layout, keep a clearance of at least one component width (3.2 mm) from sensitive analog or RF circuits, or orient the inductor so its open magnetic path points away from the noise-sensitive zone.

Frequently asked questions

What is the closest alternative to LQH32MN470J23L in the same series?

Within the LQH32 series, the base product number LQH32MN covers multiple inductance values and tolerances. No pin-compatible direct replacement is recorded for this exact 47 µH ±5% variant; the closest functional peer would be a same-inductance, same-tolerance part from the same series family, but the evidence does not name a specific order code.
