150 µH wirewound in a 1210 footprint
The LQH32DN151K23L is a Murata drum-core wirewound inductor rated 150 µH ±10% at 1 MHz test frequency, with an 80 mA current rating and 6.63 Ohm max DCR. The 80 mA current rating is the DC bias current at which inductance typically drops by 10% — derate for ambient temperature above 85 °C and for AC ripple content that adds core loss heating.
Unshielded construction and layout considerations
Unshielded means the magnetic field radiates from the core — keep a clearance of at least one part width (3.2 mm) from adjacent inductors and from sensitive analog or RF traces to avoid crosstalk. The ferrite core material gives a self-resonant frequency of 8 MHz; above that the impedance turns capacitive, so this part suits DC-DC converter output filtering and bias-T applications up to a few MHz. Surface-mount 1210 (3225 metric) footprint, 3.20 x 2.50 mm body, 2.20 mm seated height — fits standard pick-and-place with reflow soldering; the nonstandard case code means verify the land pattern against the manufacturer's recommended pad layout.
