1210 footprint, 270 nH, 1.25 A — power rail filter fit
The LQH32CHR27M33L: The unshielded construction and ferrite core mean the magnetic field extends beyond the package — adjacent traces or low-impedance components should be kept at least one package width away to avoid coupling. The 250 MHz self-resonant frequency gives clean inductive behavior up into the VHF band, making it suitable for DC-DC converter output filters and high-frequency decoupling where the 270 nH value lands in the passband.
Current rating and DCR — the thermal budget decision
The 1.25 A current rating is the saturation or temperature-rise limit at 25°C ambient — above this the inductance rolls off as the core approaches saturation, and the I²R loss in the 34 mOhm DCR accelerates self-heating. The ±20% tolerance on the 270 nH nominal means the actual inductance can range from 216 nH to 324 nH. In a resonant or filter circuit, this spread shifts the corner frequency — design the surrounding network with enough margin that the filter still meets rejection targets at the tolerance extremes.
Active production — supply chain posture
For BOM planning, this part is single-sourced to Murata — there is no pin-compatible second source listed. If dual-sourcing is required, a parametric search for a 270 nH, 1.25 A, 1210 unshielded inductor from another manufacturer would need to match the footprint and the 34 mOhm DCR ceiling to avoid thermal issues.
