330 µH wirewound for low-current filtering
The Murata LQH32CN331K23L is a drum-core wirewound inductor in the LQH32 series, delivering 330 µH ±10% in an unshielded 1210 (3225 Metric) SMD package. Rated for 60 mA DC with a maximum DCR of 13 Ohm, it is sized for signal-line filtering, bias-tee networks, or low-power DC-DC output ripple attenuation where the current draw stays well under 60 mA.
What the ratings mean for your circuit
The 330 µH value at 1 MHz test frequency and a self-resonant frequency of 5.6 MHz mean the inductor behaves inductively up to about 5.6 MHz; above that, parasitic capacitance dominates and the impedance drops — keep the switching or signal frequency below that ceiling. An unshielded drum-core construction means the magnetic field extends beyond the component body — adjacent traces or other inductors on a tight layout may couple noise, so maintain spacing or orient the part to minimize cross-talk.
Supplied on tape and reel (cut tape available) — the 330 µH value is marked on the body, but the unshielded construction means orientation in the reel pocket is not polarity-sensitive.
