Active production, 470 nH shielded inductor for power rail filtering
The Murata LQH32PNR47NN0L is an active-production shielded wirewound inductor in the LQH32 series, specified for 470 nH ±30% with a 2.55 A continuous current rating and a 3.4 A saturation current floor.
Self-resonant frequency and saturation margin
A 100 MHz self-resonant frequency means the inductance stays flat well above the switching frequencies of common buck converters (300 kHz to 2 MHz), so the effective inductance at the switching harmonic is still close to 470 nH. The 3.4 A saturation current provides 33% headroom above the 2.55 A rated current — the inductance does not roll off sharply until the load transient exceeds the continuous rating, which is useful for applications with short-duration current spikes.
Supplied on tape and reel (cut tape option available), the part is ready for high-volume assembly lines without a package change.
