470 nH at 1.1 A — the BOM-fit parameters
The LQH32CNR47M33L is a drum-core wirewound inductor from Murata's LQH32 series, specified at 470 nH ±20% with a 1.1 A continuous current rating and a maximum DCR of 54.6 mOhm. The 470 nH value and the 1.1 A rating together define the usable DC bias range — at the rated current the inductance typically drops due to core saturation, so the 1.1 A figure is the thermal limit, not the saturation knee. The ±20% tolerance on the nominal inductance means the filter corner frequency in a buck converter or PI filter can shift by that spread across reels; a tighter-tolerance part may be needed for frequency-sensitive designs.
Package and self-resonant ceiling
The self-resonant frequency is 150 MHz; above that the part behaves capacitively, so the useful frequency band for filtering or DC-DC switching is well below 150 MHz. The inductance is tested at 1 MHz, the standard test frequency for this value.
Temperature grade and sourcing posture
Lifecycle status is Active, meaning Murata continues to manufacture the LQH32CNR47M33L without a last-time-buy notice. Sourced through independent distribution; current pricing and reel quantities confirmed at RFQ against the BOM line.
