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.","metaTitle":"Murata LQH32CHR27M33L 270nH Unshielded Inductor, 1.25A","metaDescription":"Murata LQH32CHR27M33L drum core wirewound inductor, 270 nH ±20%, 1.25 A rated current, 34 mOhm DCR, 250 MHz SRF.
