1 µH, 2.05 A, Shielded — the DC resistance sets the loss budget
The Murata LQH32PH1R0NN0L is a 1 µH shielded wirewound inductor in the LQH32 series, rated for 2.05 A continuous with a maximum DC resistance of 54 mOhm. At full rated current, the I²R loss is 227 mW — that is the self-heating floor before core losses add in. The saturation current is 2.3 A, so the inductor holds its inductance past the continuous rating; the DCR, not the saturation knee, is the practical current limit in most power rail filters. Shielded construction keeps the magnetic field contained — important when the inductor sits near sensitive analog or RF stages on the same board. The ferrite core is the standard material for this inductance and frequency range; self-resonant frequency is 100 MHz, well above the 1 MHz test frequency and typical switching-regulator bands.
AEC-Q200 qualification and operating envelope
Rated AEC-Q200, this inductor passed the automotive-grade stress tests: thermal shock, vibration, moisture resistance, and solder heat. For an infotainment head unit, ADAS camera module, or body-control ECU that stays inside 85°C ambient, this part fits without derating margin concerns. The nonstandard package code just means it is not a standard JEDEC outline, but the land pattern matches the 1210 footprint used across the LQH32 family.
Active production — no lifecycle risk for new designs
Product status is Active — Murata continues to manufacture this order code. No last-time-buy, no phase-out notice. Tolerance is ±30% — typical for power-grade ferrite inductors where the DC bias characteristic dominates the effective inductance more than the initial tolerance. The inductance is tested at 1 MHz; the actual in-circuit value under DC bias will shift, so the tolerance band is wider than a signal-grade inductor would carry.
