15 µH drum core for power rail filtering
The Murata LQH32CH150K53L is a 15 µH wirewound drum core inductor in the LQH32 series, built for surface-mount power rail and signal filtering where the DC resistance and current rating define the fit. Unshielded construction means the external field couples into nearby traces or components — keep sensitive analog or RF routing at least one package width away from this footprint.
Self-resonant frequency and impedance profile
The self-resonant frequency is 26 MHz — above this point the inductor behaves capacitively, so the effective filtering band for this 15 µH part tops out well before that, typically around one decade below SRF for a clean roll-off. Inductance is tested at 1 MHz, which is the standard test frequency for this value range — the actual inductance at DC or at the switching frequency of a converter will differ slightly due to the core material's permeability curve, but the ±10% tolerance covers the spread. The ferrite core material gives a stable inductance over temperature up to 85°C, though the DCR will rise with temperature — budget a 20-30% increase in copper loss at the upper end of the range.
1210 footprint and board integration
Tape-and-reel packaging supports automated pick-and-place; the reel quantity is not listed here, but the LQH32 family typically ships in 2000-piece reels — confirm the reel count at quote time for your batch size.
