15 µH shielded power inductor for DC-DC filter stages
The Murata LQH32PB150MNCL is a 15 µH drum-core wirewound inductor in the LQH32 series, shielded for use in power-supply filter circuits where radiated noise must be contained. Rated for 330 mA continuous current with a saturation current floor of 800 mA, it suits low-to-moderate current rails in portable or embedded designs.
DC resistance and self-resonant frequency
Maximum DCR is 570 mOhm — the I²R loss at 330 mA is about 62 mW, a figure that keeps the component within its temperature rise budget in free-air on a standard PCB. Self-resonant frequency is 20 MHz, meaning the inductor behaves as an inductor well into the low-MHz switching range typical of buck converters; above SRF the impedance turns capacitive.
Package and mounting for 1210 footprint
The ferrite core and shielded construction reduce coupling to adjacent traces, simplifying layout for noise-sensitive analog or RF sections on the same board.
