15 µH, 700 mA — shielded ferrite for DC-DC output filtering
The LQH32PN150MNCL is a 15 µH shielded wirewound inductor from Murata's LQH32 series, rated for 700 mA continuous current with a DCR of 570 mOhm max and an 800 mA saturation current. The shielded ferrite core contains the field, so it can sit next to other magnetic components on the board without coupling noise into adjacent traces — a standard requirement for a buck converter output filter where the inductor carries the ripple current.
20 MHz SRF — the usable frequency ceiling
Self-resonant frequency is 20 MHz. Above that point the inductor's impedance becomes capacitive, so the switching frequency of the converter it feeds should stay well below 20 MHz — typically 2-4 MHz for a 15 µH value, which gives the designer margin before the SRF erodes the inductance. The 1210 (3225 metric) footprint is a standard size, so alternate-sourcing from other manufacturers is straightforward if the BOM needs a second source.
Active — no end-of-life concern for current builds
Murata lists the LQH32PN150MNCL as Active.
