Product details

22 µH wirewound inductor for DC-DC filtering and signal conditioning

The Murata LQH32DN220K23L is a drum core wirewound inductor in the LQH32 series, offering 22 µH inductance with ±10% tolerance in an unshielded 1210 (3225 Metric) footprint. Rated for 250 mA continuous current with a maximum DC resistance of 923 mOhm, this part suits power rail filtering or signal conditioning where the 19 MHz self-resonant frequency keeps the inductor inductive well above the switching noise band of a typical 1–2 MHz DC-DC converter.

Parametric fit for power and signal paths

Unshielded construction means the inductor's magnetic field couples into nearby traces — keep a 2–3 mm keep-out zone around the body on the PCB layout, or switch to a shielded variant if the board has sensitive analog or RF circuitry within that radius.

Frequently asked questions

What is the self-resonant frequency of LQH32DN220K23L and why does it matter?

The self-resonant frequency is 19 MHz. Above this frequency the inductor behaves capacitively, so the 22 µH value is only valid below 19 MHz — important for filtering in DC-DC converters switching at 1–2 MHz or for signal paths below 10 MHz.
