470 nH shielded power inductor for DC-DC and supply filtering
The Murata LQH32PBR47NN0L is a drum-core wirewound inductor in the LQH32 series, shielded for reduced EMI coupling into nearby traces or components. Its 470 nH inductance with ±30% tolerance suits it for DC-DC converter output filtering, power supply rail smoothing, and high-frequency decoupling where the core material must not saturate under transient loads. Rated for 2.55 A continuous current with a maximum DC resistance of 36 mOhm, the part keeps conduction losses low in power paths. The saturation current floor of 3.4 A means the inductance holds up through load steps well above the rated current — a margin that matters when the downstream switcher demands peak current during startup or transient response.
Self-resonant frequency and temperature range
A self-resonant frequency of 100 MHz places the usable inductance range well into the HF band — the inductor behaves as an inductor (not a capacitor) up to that point, making it suitable for filtering in switch-mode supplies switching at hundreds of kHz to a few MHz.
